The system includes multiple query generation processes, a search process, and a presentation of search results that is sorted by category or type and that may be customized based on the professional discipline(or analogous personal characteristic of the user), thereby reducing the amount of time and cost required to retrieve relevant results.Keyword:Information management Retrieval system Object-Oriented1.INTRUDUCTIONThis invention relates to an information storage, searching and retrieval system that incorporates a novel organization for presentation of search results from large (gigabytes) domains of archived textual data.2.BACKGROUDN OF THE INVENTIONOn-line information retrieval systems are utilized for searching and retrieving many kinds of information. Most systems used today work in essentially the same manner; that is, users log on (through a computer terminal or personal microcomputer, and typically from a remote location), select a source of information (i.e., a particular database) which is usually something less than the complete domain, formulate a query, launch the search, and then review the search results displayed on the terminal or microcomputer, typically with documents (or summaries of documents) displayed in reverse chronological order. This process must be repeated each time another source (database) or group of sources is selected (which is frequently necessary in order to insure all relevant documents have been found).Additionally, this process places on the user the burden of organizing and assimilating the multiple results generated from the launch of the same query in each of the multiple sources (databases) that the user needs(or wants) to search. Present systems that allow searching of large domains require persons seeking information in these domains to attempt to modify their queries to reduce the search results to a size that the user can assimilate by browsing through them (thus, potentially eliminating relevant results).In many cases end users have been forced to use an intermediary (i.e., a professional searcher) because the current collections of sources are both complex and extensive, and effective search strategies often vary significantly from one source to another. Even with such guidance, potential relevant answers are missed because all potentially relevant databases or information sources are not searched on every query. Much effort has been expended on refining and improving source selection by grouping sources or database files together. Significant effort has also been expended on query formulation through the use of knowledge bases and natural language processing. However, as the groupings of sources become larger, and the responses to more comprehensive search queries become more complete, the person seeking information is often faced with the daunting task of sifting through large unorganized answer sets in an attempt to find the most relevant documents or information.3.SUMMARY OF THE INVENTIONThe invention provides an information storage, searching and retrieval system for a large domain of archived data of various types, in which the results of a search are organized into discrete types of documents and groups of document types so that users may easily identify relevant information more efficiently and more conveniently than systems currently in use. The system of the invention includes means for storing a large domain of data contained in multiple source records, at least some of the source records being comprised of individual documents of multiple document types; means for searching substantially all of the domain with a single search query to identify documents responsive to the query; and means for categorizing documents responsive to the query based on document type, including means for generating a summary of the number of documents responsive to the query which fall within various predetermined categories of document types.The query generation process may contain a knowledge base including a thesaurus that has predetermined and embedded complex search queries, or use natural language processing, or fuzzy logic, or tree structures, or hierarchical relationship or a set of commands that allow persons seeking information to formulate their queries.The search process can utilize any index and search engine techniques including Boolean, vector, and probabilistic as long as a substantial portion of the entire domain of archived textual data is searched for each query and all documents found are returned to the organizing process.The sorting/categorization process prepares the search results for presentation by assembling the various document types retrieved by the search engine and then arranging these basic document types into sometimes broader categories that are readily understood by and relevant to the user.The search results are then presented to the user and arranged by category along with an indication as to the number of relevant documents found in each category. The user may then examine search results in multiple formats, allowing the user to view as much of the document as the user deems necessary.4.BRIEF DESCRIPTION OF THE DRAWINGSFIG. 1 is a block diagram illustrating an information retrieval system of the invention;FIG. 2 is a diagram illustrating a query formulation and search process utilizedin the invention;FIG. 3 is a diagram illustrating a sorting process for organizing and presentingsearch results.5.BEST MODE FOR CARRYING OUT THE INVENTIONAs is illustrated in the block diagram of FIG. 1 , the information retrieval system of the invention includes an input/output process ,a query generation process, a search process that involves a large domain of textual data (typically in the multiple gigabyte range), an organizing process, presentation of the information to the user, and a process to identify and characterize the types of documents contained in the large domain of data.Turning now to FIG. 2, the query generation process preferably includes a knowledge base containing a thesaurus and a note pad, and preferably utilizes embedded predefined complex Boolean strategies. Such a system allows the user to enter their description of the information needed using simple words/phrases made up of "natural" language and to rely on the system to assist in generating the full search query, which would include, e.g., synonyms and alternate phraseology. The user can then request, by a command such as "VI CO 1", to view the completedocument selected from the list, giving, in this case, complete information about the identity and credentials of the expert.FIG. 3 illustrates how five typical sources of information (i.e., source records) can be sorted into many document types and then subsequently into categories. For example, a typical trade magazine may contain several types of information such as editorials, regular columns, feature articles, news, product announcements, and a calendar of events. Thus, the trade magazine (i.e., the source record) may be sorted into these various document types, and these document types in turn may be categorized or grouped into categories contained in one or more sets of categories; each document type typically will be sorted into one category within a set of categories, but the individual categories within each set will vary from one set to another. For example, one set of categories may be established for a first characteristic type of user, and a different set of categories may be established for a second characteristic type of user. When a user corresponding to type #1 executes a search, the system automatically utilizes the categories of set #1, corresponding to that particular type of user, in organizing the results of the search for review by the user. When a user from type #2 executes a search, however, the system automatically utilizes the categories of set #2 in presenting the search results to the user.The information storage, searching and retrieval system of the invention resolves the common difficulties in typical on-line information retrieval systems that operate on large (e.g., 2 gigabytes or more) domains of textual data, query generation, source selection, and organizing search results. The information base with the thesaurus and embedded search strategies allows users to generate expert search queries in their own "natural" language. Source (i.e., database) selection is not an issue because the search engines are capable of searching substantially the entire domain on every query. Moreover, the unique presentation of search results by category set substantially reduces the time and cost of performing repetitive searches in multiple databases and therefore of efficiently retrieving relevant search results.While a preferred embodiment of the present invention has been described, it should be understood that various changes, adaptations and modifications may be made therein without departing from the spirit of the invention and the scope of the appended claims.中文译文：信息管理系统Wiliam K.Thomson U.S.A摘要：一个信息存储，查询和检索系统主要应用于大(千兆字节)的需要存档的文字领域。

管理信息系统外文翻译
英文文献翻译二〇年月日科技文章摘译Definition of a Management Information SystemThere is no consensus of the definition of the term "management information system". Some writers prefer alternative terminology such as "information processing system", "information and decision system", "organizational information system", or simply "information system" to refer to the computer-based information processing system which supports the operations, management, and decision-making functions of an organization. This text uses “MIS” because it is descriptive and generally understood; it also frequently uses “information system” instead of “MIS” to refer to an organizational information system.A definition of a management information system, as the term is generally understood, is an integrated, user-machine system for providing information to support operations, management, and decision-making functions in an organization. The system utilizes computer hardware and software; manual procedures; models for analysis planning, control and decision making; and a database. The fact that it is an integrated system does not mean that it is a single, monolithic structure; rather, it means that the parts fit into an overall design. The elements of the definition are highlighted below.1 Computer-based user-machine systemConceptually, management information can exist without computer, but it is the power of the computer which makes MIS feasible. The question is not whether computers should be used in management information system, but the extent to which information use should be computerized. The concept of a user-machine system implies that some tasks are best performed by humans, while others are best done by machine. The user of an MIS is any person responsible for entering input data, instructing the system, or utilizing the information output of the system. For many problems, the user and the computer form a combined system with results obtained through a set of interactions between the computer and the user.User-machine interaction is facilitated by operation in which the user’s input-output device (usually a visual display terminal) is connected to the computer. The computer can be a personal computer serving only one user or a large computer that serves a number of users through terminals connected by communication lines. The user input-output device permits direct input of data and immediate output of results. For instance, a person using the computer interactively in financial planning poses “what if” questions by entering input at the terminal keyboard; the results are displayed on the screen in a few second.The computer-based user-machine characteristics of an MIS affect the knowledge requirements of both system developer and system user. “computer-based” means that the designer of a management information system must have knowledge of computers and of their use in processing. The “user-machine” concept means the system designer should also understand the capabilities of humans as system components (as information processors) and the behavior of humans as users of information.Information system applications should not require users to be computer experts. However, users need to be able to specify their information requirements; some understanding of computers, the nature of information, and its use in various management function aids users in this task.2 Integrated systemManagement information system typically provides the basis for integration of organizational information processing. Individual applications within information systems are developed for and by diverse sets of users. If there are no integrating processes and mechanisms, the individual applications may be inconsistent and incompatible. Data item may be specified differently and may not be compatible across applications that use the same data. There may be redundant development of separate applications when actually a single application could serve more than one need. A user wanting to perform analysis using data from two different applications may find the task very difficult and sometimes impossible.The first step in integration of information system applications is an overall information system plan. Even though application systems areimplemented one at a time, their design can be guided by the overall plan, which determines how they fit in with other functions. In essence, the information system is designed as a planed federation of small systems.Information system integration is also achieved through standards, guidelines, and procedures set by the MIS function. The enforcement of such standards and procedures permit diverse applications to share data, meet audit and control requirements, and be shares by multiple users. For instance, an application may be developed to run on a particular small computer. Standards for integration may dictate that the equipment selected be compatible with the centralized database. The trend in information system design is toward separate application processing form the data used to support it. The separate database is the mechanism by which data items are integrated across many applications and made consistently available to a variety of users. The need for a database in MIS is discussed below.3 Need for a databaseThe term “information” and “data” are frequently used interchangeably; however, information is generally defined as data that is meaningful or useful to the recipient. Data items are therefore the raw material for producing information.The underlying concept of a database is that data needs to be managed in order to be available for processing and have appropriate quality. This data management includes both software and organization. The software to create and manage a database is a database management system.When all access to any use of database is controlled through a database management system, all applications utilizing a particular data item access the same data item which is stored in only one place. A single updating of the data item updates it for all uses. Integration through a database management system requires a central authority for the database. The data can be stored in one central computer or dispersed among several computers; the overriding requirement is that there is an organizational function to exercise control.4 Utilization of ModelsIt is usually insufficient for human recipients to receive only raw data or even summarized data. Data usually needs to be processed andpresented in such a way that the result is directed toward the decision to be made. To do this, processing of data items is based on a decision model. For example, an investment decision relative to new capital expenditures might be processed in terms of a capital expenditure decision model.Decision models can be used to support different stages in the decision-making process. “Intelligence” models can be used to search for problems and/or opportunities. Models can be used to identify and analyze possible solutions. Choice models such as optimization models maybe used to find the most desirable solutionIn other words, multiple approaches are needed to meet a variety of decision situations. The following are examples and the type of model that might be included in an MIS to aid in analysis in support of decision-making; in a comprehensive information system, the decision maker has available a set of general models that can be applied to many analysis and decision situations plus a set of very specific models for unique decisions. Similar models are available for planning and control. The set of models is the model base for the MIS.The management information system (MIS) not only supports the underlying bed administrator, moreover may support the intermediate deck personnel's control check, for high level also can provide certain information. The management information system frame by four parts: Information source, information processor, information user and information superintendent. The information source is the information production place; Information processor burden task/role and so on information transmission, processing, save; The information user is the information user, carries on the decision-making using the information; The information superintendent is responsible for the information system the design, the implementation and the safeguarding. The management information system is regarded as generally a pyramid shape the structure, divides into from the lower level handling of traffic to the operating control, the control check, the topmost story strategic planning. The most basic unit greatly processes the numerous and diverse transaction information and the state information framing by the task/role.In a word, the management information system (Management InformationSystem, MIS), is by the artificial leadership, using the computer hardware, the software, the network communicates these devices and other office equipments carries on the information the collection, the transmission, the processing, the storage, the update and the safeguarding by achieved the enterprise strategy competes superior, enhances the benefit and the efficiency target, supports the enterprise the high level decision-making, the intermediate deck check and the basic unit operation integration man-machine system. MIS is the superintendent provides the report, provides the enterprise the recent situation as well as the historic record. This system main localization is aims at in the enterprise, for control function and so on level plan, check and decision-making serves, provides the data generally by the lower level handling of traffic system. MIS will be able the actual enterprise's each kind of run situation, and using the past historical data forecast future, embarks the assistance enterprise from the enterprise overall situation angle to carry on the decision-making, used the message control enterprise the behavior, helped the enterprise to achieve its plan管理信息系统的定义对于“管理信息系统”并没有一致的定义。

外文文献资料Buses and InterfacesThe buses and interfaces are the fabric that connects the CPU to the peripherals that are part of the system. Each bus and interface has its own intricacies, and the level of support provided by Linux to the different buses and interfaces varies accordingly. The following is a rundown of the buses and interfaces found in embedded systems and a discussion of their support by Linux. Linux supports many other buses, such as SBus, NuBus, TurboChannel, and MCA, but these are workstation or server-centric.1. ISAThe Industry Standard Architecture (ISA) bus was designed for and occupied the core of PC-AT architecture. It was odd even for its time, as it did not provide many of the facilities other buses offered, including ease of mapping into normal processor physical address space. Its simplicity, however, favored the proliferation of many devices for the PC, which, in turn, favored the use of PCs in embedded applications.ISA devices are mostly accessed through the I/O port programming already available in the x86's instruction set. Therefore, the kernel does not need to do any work to enable device drivers to use the bus. Instead, the various device drivers access the appropriate I/O ports directly using the in/out assembly functions. Although the kernel provides support for Plug and Play (PNP) devices, this capability is of little use for embedded applications. Instead, embedded systems that do need to support hardware variations will be based on buses that support runtime hardware addition and removal, such as CompactPCI, PCMCIA, and USB. The kernel also supports Extended ISA (EISA) devices, but this bus has not been very popular and has been superseded by the PCI bus.2. PCIThe Peripheral Component Interconnect (PCI) bus, managed by the PCI Special Interest Group (PCI-SIG), is arguably the most popular bus currently available. Designed as a replacement for ISA, it is used in combination with many different architectures, including the PPC and the MIPS, to build different types of systems,including embedded devices.Unlike ISA, PCI requires software support to enable it to be used by device drivers. The first part of this support is required to initialize and configure the PCI devices upon bootup. On PC systems, this is traditionally done by the BIOS. However, the kernel is capable of carrying out this task itself. If the BIOS has carried out the initialization, the kernel will browse the BIOS's table to retrieve the PCI information. In both cases, the kernel provides device drivers with an API to access information regarding the devices on the PCI bus and act on these devices. There are also a number of user tools for manipulating PCI devices. In short, the level of support for PCI in Linux is fairly complete and mature.3.PCMCIAPersonal Computer Memory Card International Association (PCMCIA) is both the common name of a bus and the name of the organization that promotes and maintains related standards. Since the publication of the initial standard, which supported only 16-bit cards, other standards have been published, including the 32-bit CardBus and the USB CardBay specifications. When part of an embedded system, PCMCIA renders it flexible and easy to extend. On the iPAQ, for instance, it enables users to connect to a LAN using a wireless networking card. In other systems, it makes large permanent storage space available through the use of CompactFlash cards.The extent of Linux support for PCMCIA can be confusing. First and foremost, there is the main Linux PCMCIA project, which is hosted on SourceForge at :/// and is maintained by David Hinds. The package made available by this project supports a large number of cards, Linux support for PCMCIA is quite mature for the i386 architecture and available in part for the PPC, but unfortunately, it's still in its infancy for other chips at the time of this writing. Apart from the package maintained by Hinds, the official kernel contains support for a portion of the PCMCIA cards supported by the Hinds' package. The developers' intent is to have the official kernel become the main source for PCMCIA support. Until then, the best choice is to use Hinds' distribution for production systems. It includes the necessary system tools to configure the automatic loading and unloading of the appropriate PCMCIA device drivers when a card is inserted or removed from a PCMCIA slot.4. PC/104Although simple, the ISA bus is not well adapted to the rugged environments where embedded systems are deployed. The PC/104 form factor was introduced toaddress the shortcomings of ISA's mechanical specification. PC/104 provides a bus whose electrical signals are identical to those of the ISA bus, but with a different mechanical specification that is more adapted to embedded system development by providing ease of extensibility and ruggedness. Instead of using slots where cards are inserted, as in a regular ISA setup, PC/104 specifies the use of pin connectors. When PCI became popular, the PC/104+ specification was introduced to provide a PCI-signal-compatible bus as an addition to the PC/104 specification. Both PC/104 and PC/104+ are managed by the PC/104 Consortium, which includes more than a 100 member companies.The PC/104 is identical to ISA and the PC/104+ is identical to both ISA and PCI from the signal perspective and, therefore, from the software's perspective. Therefore, Linux requires no special functionality to support these buses. However, this does not mean that Linux supports all PC/104 and PC/104+ devices. As with any other ISA or PCI device, you should seek exact information about Linux compatibility with the PC/104 device you are evaluating.5. VMEThe VME bus is largely based on Motorola's VERSA backplane bus, which was developed specifically for the 68000 in 1979. At the time, VERSA was competing with buses such as Multibus, STD, S-100, and Q-bus, although it is rarely used today. Striving to provide a new bus that would be microprocessor independent, Motorola, Mostek, and Signetics agreed that the three companies would support a new bus. This came to be the VME bus based on the VERSA's electrical signals and the Eurocard mechanical form factor. In the Eurocard form factor, VME boards are loaded vertically into a VME chassis and connected to its backplane using pin connectors, unlike common computer boards that use edge connectors inserted into slots. Since its introduction, the VME bus has become widely adopted as the preferred bus for building powerful and rugged computers. One factor that has helped the VME bus' popularity is that it is an open standard that isn't controlled by any single organization.As the VME bus can accommodate multiple VME boards, each with its own CPU and OS, no central OS controls the bus. Instead, arbitration is used to permit a board to become bus master momentarily to conduct its operations. The job of Linux on a VME board is therefore to interact properly with its VME hardware interface to obtain the appropriate functionality.pactPCIThe CompactPCI specification was initiated by Ziatech and was developed by members of the PCI Industrial Computer Manufacturer's Group (PICMG), which oversees the specification and promotes the use of CompactPCI. The CompactPCI specification provides an open and versatile platform for high-performance, high-availability applications. Its success is largely based on the technical choices made by its designers. First, they chose to reuse the Eurocard form-factor popularized by VME. Second, they chose to make the bus PCI-compatible, hence enabling CompactPCI board manufacturers to reuse low-cost PCI chips already available in the mainstream market.Technically, the CompactPCI bus is electrically identical to the PCI bus. Instead of using slot connections, as found in most workstations and servers, pin connectors are used to connect the vertically loaded CompactPCI boards to the CompactPCI backplane, much like VME. As with PCI, CompactPCI requires a single bus master, in contrast with VME, which could tolerate multiple bus masters, as explained earlier. Consequently, CompactPCI requires the permanent presence of a board in the system slot. It is this board that arbitrates the CompactPCI backplane, just as a PCI chipset would arbitrate a PCI bus in a workstation or a server.In addition, the CompactPCI specification allows for the implementation of the Hot Swap specification, which describes methods and procedures for runtime insertion and removal of CompactPCI boards. This specification defines three levels of hot swapping. Each level implies a set of hardware and software capabilities. Here are the available levels and their requirements: Basic hot swapThis hot swap level involves console intervention by the system operator. When a new card is inserted, she must manually inform the OS to power it up and then configure and inform the software of its presence. To remove a card, she must tell the OS that the board is about to be removed. The OS must then stop the tasks that are interacting with the board and inform the board to shut down.Full hot swapIn contrast to basic hot swap, full hot swap does not require console intervention by the operator. Instead, the operator flips a microswitch attached to the card injector/ejector to notify the OS of the impending removal. The OS then performs the necessary operations to isolate the board and tell it to shut down. Finally, the OS lights an LED to notify the operator that the board can now be removed. On insertion, the OS carries out the inverse operations when it receives the appropriate insertion signal.High AvailabilityIn this level, CompactPCI boards are under complete software control. A hot swap controller software manages the state of all the boards in the system and can selectively reverse these individual boards according to the system's state. If a board fails, for example, the controller can shut it down and power up a duplicate board that is present within the same chassis for this very purpose. This hot swap level is called "High Availability," because it is mostly useful in what are known as high-availability applications，such as telecommunications, where downtime must be minimal.Linux accommodates the basic CompactPCI specification, through the PCI support it already provides. Support for dynamic insertion and removal of devices in Linux also exists in different forms. Primarily, Version 2.4 of the kernel includes the required kernel functionality.That said, this level of support is insufficient to accommodate all the complexities of CompactPCI systems. In addition, there are few drivers within the main kernel tree for mainstream CompactPCI boards, although CompactPCI board manufacturers may provide Linux drivers. This caveat has led to the emergence of a number of commercial solutions that provide high-availability Linux solutions on CompactPCI, including Availix's HA Cluster and MontaVista's High Availability Framework. The ongoing High-Availability Linux Project, found at :///, aims at providing the open source components needed to build high-availability solutions using Linux. The project isn't restricted to a specific hardware configuration and is, therefore, not centered around CompactPCI.In the future, we may see more open source software accommodating the various complexities of CompactPCI-based systems, both in terms of hot swap capabilities and in terms of software support for communication, resource monitoring, cluster management, and other software components found in high-availability systems. For now, however, if you want to use Linux for a CompactPCI-based high-availability application, you may need to work with one of the existing commercial solutions to obtain all the features described by the CompactPCI specification.7. Parallel PortAlthough not a bus in the traditional sense, the parallel port found in many computers can be used to connect a wide range of peripherals, including hard drives, scanners, and even network adapters. Linux support for parallel port devices is extensive, both in terms of the drivers found in the kernel and the ones providedby supporting projects. There is no central authority or project, however, that directs Linux's support for parallel port devices, since the parallel port is a ubiquitous component of computer systems. Instead, there are good resources that describe which devices are supported. These include the Hardware Compatibility HOWTO found at the LDP and the Linux Parallel Port Home Page found at :// /linux-pp.html. It is worth noting that Linux supports the IEEE1284 standard that defines how parallel port communication with external devices is carried out.As the parallel port can be used for many purposes besides attaching external devices, I will discuss parallel port programming when explaining the use of the parallel port as in an I/O interface in Section 3.3.8. SCSIThe Small Computer Systems Interface (SCSI) was introduced by Shugart Associates and eventually evolved into a series of standards developed and maintained by a series of standard bodies, including ANSI, ITIC, NCITS, and T10. Although mainly thought of as a high-throughput interface for hard drives for high-end workstations and servers, SCSI is a general interface that can be usedto connect various hardware peripherals. Only a small segment of embedded systems ever use SCSI devices, though. These systems are typically high-end embedded systems such as the CompactPCI-based high-availability systems discussed earlier.In those cases, a CompactPCI SCSI controller inserted in the CompactPCI backplane provides an interface to the SCSI devices.If you consider using SCSI in an embedded system, note that although Linux supports a wide range of SCSI controllers and devices, many prominent kernel developers believe that the kernel's SCSI code requires major work or even a complete rewrite. This doesn't mean that you shouldn't use SCSI devices with Linux.It is only a warning so that you plan your project's future updates in light of such possible modifications to the kernel's SCSI layer. At the time of this writing, work on the SCSI code has not yet started. It is expected that such work wouldbe undertaken during the 2.5 development series of the kernel. For now, the SCSI hardware supported by Linux can be found in the Hardware Compatibility HOWTO from the LDP. As with the parallel port, there is no single reference point containingall information regarding Linux's support for SCSI, since the SCSI interface isan established technology with a very large user base.Discussion of the kernel's SCSI device drivers architecture can be foundat :// /sg/, at :// /scsi.html, and in theLinux 2.4 SCSI subsystem HOWTO from the LDP. This should be the starting point for the development of any SCSI driver for Linux, along with the Linux Device Drivers book by O'Reilly. For a broad discussion about SCSI, The Book of SCSI: I/O For The Millennium by Gary Field and Peter Ridge (No Starch Press) is a good start. As with other standards, there are always official standards documents provided by the standard bodies, but again, such documentation often makes for dry reading material.9. USBThe Universal Serial Bus (USB) was developed and is maintained by a group of companies forming the USB Implementers Forum (USB-IF). Initially developed to replace such fragmented and slow connection interfaces as the parallel and serial ports traditionally used to connect peripherals to PCs, USB has rapidly established itself as the interface of choice for peripherals by providing inexpensive ease of use and high-speed throughput. Although mainly a mainstream device-oriented bus, USB is increasingly appearing in hardware used in embedded systems, such as SBCs and SoCs from several manufacturers.USB devices are connected in a tree-like fashion. The root is called the root hub and is usually the main board to which all USB devices and nonroot hubs are connected. The root hub is in charge of all the devices connected to it, directly or through secondary hubs. A limitation of this is that computers cannot be linked in any form of networking using direct USB cabling.There are also USB network adapters, including Ethernet adapters, that can be used to connect the computers to a common network.Support within Linux for behaving as a USB root hubis quite mature and extensive, comparing positively to the commercial OSes that support USB. Although most hardware vendors don't ship Linux drivers with their USB peripherals, many have helped Linux developers create USB drivers by providing hardware specifications. Also, as with other hardware components, many Linux drivers have been developed in spite of their manufacturers' unwillingness to provide the relevant specifications. The main component of Linux's support for USB is provided by the USB stack in the kernel. The kernel also includes drivers for the USB devices supported by Linux. User tools are also available to manage USB devices. The user tools and the complete list of supported devices is available through the Linux USB project web site at :// /.Support within Linux for behaving as a USB device is limited in comparison to its support for behaving as a USB root hub. While some systems running Linux,such as the iPAQ, can already behave as devices, there is no general agreed-upon framework yet for adding USB device capabilities to the Linux kernel.Development of USB drivers is covered by the Programming Guide for Linux USB Device Drivers by Detlef Fliegl, available through the Linux USB project web site. The Linux Device Drivers book also provides guidelines on how to write Linux USB drivers. There are a number of books that discuss USB, which you can find by looking at the various online bookstores. However, the consensus among developers and online book critics seems to indicate that the best place to start, as well as the best reference, is the original USB specification available online from the USB-IF.10. IEEE1394 (FireWire)FireWire is a trademark owned by Apple for a technology they designed in the late 80s/early 90s. They later submitted their work to the IEEE and it formed the basis of what eventually became IEEE standard 1394. Much like USB, IEEE1394 enables devices to be connected using simple and inexpensive hardware interfaces. Because of their similarities, IEEE1394 and USB are often considered together. In terms of speed, however, it is clear that IEEE1394's architecture is much more capable than USB of accommodating throughput-demanding devices, such as digital cameras and external hard drives. Recent updates to the USB standard have reduced the gap, but IEEE1394 still has a clear advantage in regards to currently existing high-throughput devices and future capabilities. Although only a small number of embedded systems actually use IEEE1394, it is likely that the need for such a technology will increase with the demand in throughput.In contrast to USB, IEEE1394 connections do not require a root node. Rather, connections can be made either in a daisy-chain fashion or using an IEEE1394 hub. Also, unlike SCSI, connections do not need any termination. It is also possible to connect two or more computers directly using an IEEE1394, which isn't possible with USB. To take advantage of this capability, there is even an RFC specifying how to implement IP over IEEE1394. This provides an inexpensive and high-speed network connection for IEEE1394-enabled computers.Linux's support for IEEE1394 isn't as extensive as that provided by some commercial OSes, but it is mature enough to enable the practical, every day use of quite a number of IEEE1394 hardware devices. The kernel sources contain the code required to support IEEE1394, but the most up-to-date code for the IEEE1394 subsystem and the relevant user utilities can be found at the IEEE1394 for Linux project web site at :// /. The list of supported devices canbe found in the compatibility section of the web site. The number and types of devices supported by Linux's IEEE1394 can only increase in the future.Support for running an IP network over IEEE1394 in Linux is currently in its infancy. In due time, this may become a very efficient way of debugging embedded Linux systems because of the quantity of data that can be exchanged between the host and the target.Documentation on how to use the IEEE1394 subsystem under Linux with supported hardware can be found on the IEEE1394 for Linux project web site. The web site also includes links to documentation regarding the various specifications surrounding IEEE1394. The main standard itself is available from the IEEE and is therefore expensive for a single individual to purchase. Although the standard will be a must for any extensive work on IEEE1394, the FireWire System Architecture book by Don Anderson (Addison Wesley) is a good place to start.11.GPIBThe General-Purpose Interface Bus (GPIB) takes its roots in HP's HP-IB bus, which was born at the end of the 1960s and is still being used in engineering and scientific applications. In the process of maturing, GPIB became the IEEE488 standard and was revised as late as 1992. Many devices that are used for data acquisition and analysis are, in fact, equipped with a GPIB interface. With the advent of mainstream hardware in this field of application, many GPIB hardware adapters have been made available for such mainstream hardware and for PCs in particular.GPIB devices are connected together using a shielded cable that may have stackable connectors at both ends. Connectors are "stackable" in the sense that a connector on one end of a cable has the appropriate hardware interface to allow for another connector to be attached to it, which itself allows another connector to be attached. If, for instance, a cable is used to connect a computer to device A, the connector attached to A can be used to attach the connector of another cable going from A to device B.12. I2CInitially introduced by Philips to enable communication between components inside TV sets, the Inter-Integrated Circuit (I2C) bus can be found in many embedded devices of all sizes and purposes. As with other similar small-scale buses such as SPI and MicroWire, I2C is a simple serial bus that enables the exchange of limited amounts of data among the IC components of an embedded system. There is a broad range of I2C -capable devices on the market, including LCD drivers, EEPROMs, DSPs, and so on. Because of its simplicity and its hardware requirements, I2C can beimplemented either in software or in hardware.Connecting devices using I2C requires only two wires, one with a clock signal, serial clock (SCL), and the other with the actual data, serial data (SDA). All devices on an I2C bus are connected using the same wire pair. The device initiating a transaction on the bus becomes the bus master and communicates with slaves using an addressing scheme. Although I2C supports multiple masters, most implementations have only one master.The main kernel tree includes support for I2C, a number of devices that use I2C, and the related System Management Bus (SMBus). Due to the heavy use of I2C by hardware monitoring sensor devices, the I2C support pages are hosted on the Linux hardware monitoring project web site at ://www2.lm-sensors.nu/~lm78/. The site includes a number of links, documentation, and the most recent I2C development code. Most importantly, it contains a list of the I2C devices supported along with the appropriate driver to use for each device.中文翻译稿应用技术学院06计算机（0616403062）管玲玲2010年2月总线和接口总线和接口是连接CPU到系统的部分外设的组织。

管理信息系统的外文原文
附件： 2.外文原文Our Work In Management Information SystemsINTRODUCTION TO MISWhat is "Management Information Systems (MIS)"?Field Began in Early 80s MIS bridges the gap between end-users and technical staffs (e.g. programmers) Consider the three key words (management, information, & systems) that have significant implications:Management:Managing resources that include people, machinery (technology and computers),money, and time, etc. You have to consider three managerial factors together in MIS: effectiveness, efficiency and profitability.Effectiveness – how well a firm is pursuing a goal or objective of its business; for instance, providing quality product/service can be a business goal that is usually stated in a firm's mission statement; Management by objective (MBO), etc.Efficiency – best use of resources, a synonym is productivity = output divided by input. Productivity is measured in general by a ratio of OUTPUT to INPUT. Here, output indicates revenue, market share, etc., while input indicates labor, raw materials, administrative costs, operations costs, and IT related costs.Profitability - The empirical studies in the IS literature have reported that on the contrary to the management's belief, there exists no significant difference in the profitability between before and after the new IS implementation. In other words, the new IS does not make significant profitability increase whatsoever. In general, the bottom line in any business is the profitability. If it does not enhance the profitability, then what is a point to go through all the trouble to develop/implement a new IS? Using IT is not the perfect solution for every business situation. Whenever a new IT or information systems (IS) are implemented, additional costs incur. They can be costs related to hardware, software, training, maintenance, etc. Therefore, the cost-benefit analysis should be conducted prior to a new systems implementation.InformationRelates to the computer; refers to knowledge. Data are a source for the information. If the data are processed in a meaningful way, they become "information." Here, IT can contribute. Information can be extracted easily through IT (e.g. computer) if data are properly processed. Therefore, the second word in M.I.S. indicates IT or computer. Of course, information can be obtained by a primitive way such as manual sorting, etc. by a clerk. Using IT definitely outperform any other means in history, in terms of processing data.SystemsIf a nice system is made, it is self-running which leads to reducing the people necessary to the business process. Systems Theory, Systems approach Systematically doing business Systems comes from systems theory that stresses the importance of systems approach to problem solving and a structured way to control and adjust automatically. Computer programmers and software engineers/developers realized it was only way to reduce a possibility of encountering errors later in the systems development process. When you construct a new/better system for the current business operations/decision-making process, you don't want to make a computer program based on the current business way. Instead, you develop a new model after serious analysis of the current system, so later can save resource in terms of time and money by avoiding a possible mistake/error. Therefore, business process reengineering (BPR) is unthinkable without a sound understanding of systems theory/concepts.MIS is a field of science that studies on (1) how better we can manage technologies (2) how better we can design information systems, in order to enhance a firm's effectiveness, efficiency and profitability.MIS is a new subject in the last ten to fifteen years. The idea is still being researched since the concept is being evolved. A teacher's bias has a large impact on this type of subject. Classification of Specialties in MIS∙Systems Planning∙Systems Development∙Systems Review and Enhancement∙Special Computer ApplicationsSystems Planning - facilities planning, distributed processing systems, systems organization, management and staff development and training, and application of new technologies.Systems Development - feasibility study and cost benefit analysis, development of detailed system specifications, equipment selection and configuration, software procurement / technical supervision of programming, implementation assistance, documentation and user training.Systems Review and Enhancement - re-evaluation of information processing requirements, complete information system productivity audits, hard-ware/software performance evaluation and fine tuning, assessment and improvement of application program efficiency, staff productivity, data processing operations, studies of system development and testing procedures, environment, security and reliability.Special Computer Applications - production planning and scheduling, inventory control,re-source allocation, transportation and distribution logistics, least-cost formulation, personnel planning and administration, project management/control, system simulation, corporate models, information retrieval and analysis, process control, scientific and engineering applications.Our Approach to MIS DesignAll modern organizations are characterized by the need for management information. However this need is met, from the simplest verbal reporting system to the most sophisticated computerized system, certain basic principles must be observed if the information provided is to contribute to effective management, at a reasonable cost. Management information must be timely, accurate and in a format that lends itself to decision making. The cost of obtaining it must not exceed its value in the decision making process.RMC believes that an information system must be designed to take account of the nature of the client's business, the structure of the organization and the managerial styles of the system users. Data to be processed should be captured once only - and preferably by those who originate it and are most familiar with it. This means that the information system must be geared for simple yet efficient use by operators with minimal system training, and must facilitate input error detection and correction. Our goals in information system design are to provide maximum flexibility and growth capacity for the system while minimizing operating costs and implementation disruptions.System Performance AuditOnce established, an information system must be audited periodically to ensure that it is performing all the tasks required of it as efficiently and effectively as possible. Growth of the organization, increased volume of business, changes in the business environment, technological changes and newly conceived information requirements all place increased demands on existing information systems and often cause them to be modified or extended on an ad hoc basis.Our staff has the specialized skills and experience to perform a thorough audit on existing information systems and to recommend changes in design, equipment, software and procedures, to bring them up-to-date and to peak performance.An information system audit should be performed every three years, or when processing capacity appears to be strained and upgrading of facilities is being considered.Typical AssignmentsAs part of the Guyana Health Sector Policy and Institutional Development Program funded by IADB, RMC designed a financial MIS/accounting system for health care delivery at the national/regional level and for the principal acute care facility in Georgetown.IS/IT Strategic Planning Review for the Trinidad & Tobago Ministry of Health. Assessment of the IS/IT requirements of the Directorate of Quality Management, and a recommended course of action with respect to the multi-year $135 million IADB funded Health Sector Reform Program leading to the establishment of a National Health Information Centre and the coordination of IS/IT upgrades for the principal medical sciences centre in the country.Secondment of a Senior Principal for a one year period to be the Director of the Project Management Office (PMO) of a Smart Systems for Health project of the Ontario Ministry of Health. The objectives for the PMO was to design infrastructure to deliver Smart System products and services; establish standards and policy for the future use of the technology; recommend governance, financing and security policies; coordinate efforts of health sector and technology partners; and raise health policy issues for determination by the Ministry of Health. About 80 professionals, including three from RMC were involved during the course of the project.In RMC's capacity as Advisors to the Estonia / World Bank Health Project, several information systems were developed and implemented for the Project Coordination Unit (PCU) at the Estonian Ministry of Social Affairs. These included:a comprehensive project accounting system to address all of the financial reporting requirements.a project management system to facilitate the planning, scheduling and progress monitoring of project tasks. This system schedules and monitors project procurement activities for performance, scheduling and cost control.Corporate Subject Database Profiles to serve as the initial guide for developing a comprehensive information system to support the broad information requirements associated with Estonia's future health financing system.Similar to the Estonia project, an assignment was conducted for the Republic of Georgia World Band Health Project; and for the Albania World Bank Health Project.As part of RMC's work advising Poland on restructuring its health services, our professional staff assisted the Ministry of Health and Social Welfare to develop an information systems strategy and determine appropriate computer hardware and software requirements. At the national and regional levels, the scope of our work included establishing MIS for planning andmonitoring the delivery of health services. At the institutional level, our work covered the development of a comprehensive program for the acquisition of computer systems.RMC designed a comprehensive portfolio of computerized health management information systems for the Ugandan Ministry of Health to support national and district health information needs. This included systems to gather and manage data resources; analyze the public's health status; plan the program, service and resource requirements; monitor the effectiveness, cost and efficiency of the health care delivery systems; and support research and development initiatives. Conceptual design of an integrated health care planning system and related planning models was also developed as a by-product of this project.RMC analyzed the existing accounting and management information system for the delivery of health care services in the Bahama s, then designed and initiated an implementation program of an improved, integrated, computerized accounting and management information system for the Ministry of Health and the two hospitals. RMC also developed productivity standards for the MIS based on the Canadian Health Association's MIS guidelines, modified to reflect the Bahamian environment.RMC worked jointly with the provinces of British Columbia, Ontario and Nova Scotia on computer assisted planning for Alberta Hospitals and Medical Care. The Phase 1 feasibility study assessed extent, costs and implications of developing a computer-based tool to facilitate all pre-design and functional planning. Phase 2 included development of software and hardware requirements.。

The Design and Development of the Students' Information Management SystemAs information technology advances, various management systems have emerged to change the daily lives of the more coherent, to the extent possible, the use of network resources can be significantly reasonable reduction of manual management inconvenience and waste of time.Accelerating the modernization of the 21st century, the continuous improvement of the scientific and cultural levels, the rapid growth of the number of students will inevitably increase the pressure information management students, the inefficient manual retrieval completely incompatible with the community\'s needs. The Student Information Management Systemis an information management one kind within system, currently information technique continuously of development, the network technique has already been applied in us extensively nearby of every trade, there is the network technical development, each high schools all make use of a calculator to manage to do to learn, the school is operated by handicraft before of the whole tedious affairs all got fast and solve high-efficiencily, especially student result management the system had in the school very big function, all can be more convenient, fast for the student and the teacher coming saying and understand accurately with management everyone noodles information. AbstractIt is a very heavy and baldness job of managing a bulky database by manpower. The disadvantage, such as great capacity of work, low efficiency and long period, exist in data inputting, demanding and modification. So the computer management system will bring us a quite change.Because there are so many students in the school, the data of students' information is huge, it makes the management of the information become a complicated and tedious work. This system aims at the school, passing by practically of demand analysis, adopt mighty VB6.0 to develop the student information managementsystem. The whole system design process follow the principle of simple operation, beautiful and vivid interface and practical request. The student information management system including the function of system management, basic information management, study management, prize and punishment management , print statement and so on. Through the proof of using, the student information management system which this text designed can satisfy the school to manage the demand of the aspect to students' information. The thesis introduced the background of development, the functions demanded and the process of design. The thesis mainly explained the point of the system design, the thought of design, the difficult technique and the solutions. The student managed the creation of the system to reduce the inconvenience on the manpower consumedly, let the whole student the data management is more science reasonable.The place that this system has most the special features is the backstage database to unify the management to student's information.That system mainly is divided into the system management, student profession management, student file management, school fees management, course management, result management and print the statement.The interface of the system is to make use of the vb software creation of, above few molds pieces are all make use of the vb to control a the piece binds to settle of method to carry out the conjunction toward the backstage database, the backstage database probably is divided into following few formses:Professional information form, the charges category form, student the job form, student the information form, political feature form of student, the customer logs on the form The system used Client/Server structure design, the system is in the data from one server and a number of Taiwan formed LAN workstations. Users can check the competence of different systems in different users submit personal data, background database you can quickly given the mandate to see to the content.Marks management is a important work of school,the original manual management havemany insufficiencies,the reasons that,students' population are multitudinous in school,and each student's information are too complex,thus the work load are extremely big,the statistics and the inquiry have been inconvenient.Therefore,how to solve these insufficiencies,let the marks management to be more convenient and quickly,have a higher efficiency,and become a key question.More and more are also urgent along with school automationthe marks management when science and technology rapid development,therefore is essential to develop the software system of marks register to assist the school teaching management.So that can improve the marks management,enhance the efficiency of management.Systems Analysis and Design SystemsWorking under control of a stored program, a computer processes data into information. Think about that definition for a minute. Any given computer application involves at least three components: hardware, software, and data. Merely writing a program isn’t enough, because the program is but one component is in a system.A system is a group of components that work together to accomplish an objective. For example, consider a payroll system. Its objective is paying employees. What components are involved? Each day, employees record their hours worked on time cards. At the end of each week, the time cards are collected and delivered to the computer center, where they are read into a payroll program. As it runs, the program accesses data files. Finally, the paychecks are printed and distributed. For the system to work, people, procedures, input and output media, files, hardware, and software must be carefully coordinated. Note that the program is but one component in a system.Systems AnalysisComputer-based systems are developed because people need information. Those people,called users, generally know what is required, but may lack the expertise to obtain it. Technical professionals, such as programmers, have the expertise, but may lack training in the user’s field. To complicate matters, users an d programmers often seem to speak different languages, leading to communication problems. A systems analyst is a professional who translates user needs into technical terms, thus serving as a bridge between users and technical professionals.Like an engineer or an architect, a systems analyst solves problems by combining solid technical skills with insight, imagination, and a touch of art. Generally, the analyst follows a well-defined, methodical process that includes at least the following steps: Problem definitionAnalysisDesignImplementationMaintenanceAt the end of each step, results are documented and shared with both the user and the programmers. The idea is to catch and correct errors and misunderstandings as early as possible. Perhaps the best way to illustrate the process is through example.Picture a small clothing store that purchases merchandise at wholesale, displays this stock, and sells it to customers at retail. On the one hand, too much: stock represents an unnecessary expense. On the other hand, a poor selection discourages shoppers. Ideally, a balance can be achieved: enough, but not too much.Complicating matters is the fact that inventory is constantly changing, with customer purchases depleting stock, and returns and reorders adding to it. The owner would like to track inventory levels and reorder any given item just before the store runs out. For a single item, the task is easy-just count the stock-on-hand. Unfortunately, the store has hundreds of different items, and keeping track of each one is impractical. Perhaps a computer might help.Problem DefinitionThe first step in the systems analysis and design process is problem definition. Theanalyst’s objective is determining what the user needs. Note that, as the process begins, the user possesses the critical information, and the analyst must listen and learn. Few users are technical experts. Most see the computer as a “magic box,” and are not concerned with how it works. At this stage, the analyst has no business even thinking about programs, files, and computer hardware, but must communicate with the user on his or her own terms.The idea is to ensure that both the user and the analyst are thinking about the same thing. Thus, a clear, written statement expressing the analyst’s underst anding of the problem is essential. The user should review and correct this written statement. The time to catch misunderstandings and oversights is now, before time, money, and effort are wasted. Often, following a preliminary problem definition, the analyst performs a feasibility study. The study, a brief capsule version of the entire systems analysis and design process, attempts to answer three questions:1.Can the problem be solved?2.Can it be solved in the user’s environment?3.Can it be solved at a reasonable cost?If the answer to any one of these questions is no, the system should not be developed. Given a good problem definition and a positive feasibility study, the analyst can turn to planning and developing a problem solution.AnalysisAs analysis begins, the analyst understands the problem. The next step is determining what must be done to solve it. The user knows what must be done; during analysis, this knowledge is extracted and formally documented. Most users think in terms of the functions to be performed and the data elements to be manipulated. The objective is to identify and link these key functions and data elements, yielding a logical system design. Start with the system’s basic functions. The key is keeping track of the stock-on-hand for each product in inventory. Inventory changes because customers purchase, exchange, and return products, so the system will have to process customer transactions. The store’s owner wants to selectively look at the inventory level for any product in short supply and,if appropriate, order replacement stock, so the system must be able to communicate with management. Finally, following management authorization, the system should generate a reorder ready to send to a supplier.Given the system’s basic functions, the analyst’s next task is gaining a sense of their logical relation. A good way to start is by describing how data flow between the functions. As the name implies, data flow diagrams are particularly useful for graphically describing these data flows. Four symbols are used. Data sources and destinations are represented by squares; input data enter the system form a source, and output data flow to a destination. Once in the system, the data are manipulated or changed by processes, represented by round-corner rectangles. A process might be a program, a procedure, or anything else that changes or moves data. Data can be held for later processing in data stores, symbolized by open-ended rectangles. A data store might be a disk file, a tape file, a database, written notes, or even a person’s memory. Finally, data flow between sources, destinations, processes, and data stores over data flows, which are represented by arrows. Preliminary data flow diagram for the inventory system. Start a CUSTOMER. Transactions flow from a customer into the system, where they are handled by Process transaction. A data store, the STOCK, holds data on each item in inventory. Process transaction changes the data to reflect the new transaction. Meanwhile, MANAGEMENT accesses the system through Communicate, evaluating the data in STOCK and, if necessary, requesting a recorder. Once a reorder is authorized, Generate reorder sends necessary data to the SUPPLIER, who ships the items to the store. Note that, because the reorder represents a change in the inventory level of a particular product or products, it is handled as a transaction.The data flow diagram describes the logical system. The next step is tracing the data flow. Start with the destination SUPPLIER. Reorders flow to suppliers; for example, the store might want 25 pairs of jeans. To fill the order, the supplier needs the product description and the reorder quantity. Where do these data elements come from? Since they are output by Generate reorder, they must either be input to or generated by this process. Data flow into Generate reorder for STOCK; thus, product and reorder quantities must be stored inSTOCK.Other data elements, such as purchased and the purchase quantity, are generated by CUSTOMER. Still others, for example selling price and reorder point, are generated by or needed by MANAGEMENT. The current stock –on-hand for a given item is an example of a data element generated by an algorithm in one of the procedures. Step by step, methodically, the analyst identifies the data elements to be input to, stored by, manipulated by, generated by, or output by the system.To keep track of the data elements, the analyst might list each one in a data dictionary. A simple data dictionary can be set up on index cards, but computerized data dictionaries have become increasingly popular. The data dictionary, a collection of data describing and defining the data, is useful throughout the systems analysis and design process, and is often used to build a database during the implementation stage.The idea of analysis is to define the system’s major functions and data elements methodically. Remember that the objective is translating user needs into technical terms. Since the system starts with the user, the first step is defi ning the user’s needs. Users think in terms of functions and data. They do not visualize programs, or files, or hardware, and during this initial, crucial analysis stage, it is essential that the analyst think like a user, not like a programmer.Data flow diagrams and data dictionaries are useful tools. They provide a format for recording key information about the proposed system. Also, they jog the analyst’s memory; for example, if the analyst doesn’t have sufficient information to complete a data dictionary entry, he or she has probably missed something. Perhaps most importantly, the data flow diagram and the data dictionary document the analyst’s understanding of the system requirements. By reviewing these documents, the user can correct misunderstanding or oversights. Finally, they represent an excellent starting point for the next step, design.DesignAs we enter the design stage, we know what the system must do, and thus can begin thinking about how to do it. The objective is to develop a strategy for solving the problem.At this stage, we are not interested in writing code or in defining precise data structures; instead, we want to identify, at a black box level, necessary programs, files, procedures, and other components.The data flow diagram defines the system’s necessary functions; how might they be implemented? One possibility is writing one program for each process. Another is combining two or more processes in a single program; there are dozens of alternative solutions. Let’s focus on one option a nd document it.A system flowchart uses symbols to represent programs, procedures, hardware devices, and the other components of a physical system. Our flowchart shows that transaction data enter the system through a terminal, are stored on an inventory by a data collection program, and then are stored on an inventory file. Eventually, the inventory file is processed by a Report and reorder program. Through it, management manipulates the data and authorizes reorders.Look at the system flowchart. It identifies several hardware components, including a computer, a disk drive, a data entry terminal, a printer, and a display terminal. Tow programs are needed: Process transaction and Report and reorder. In addition to the hardware and the programs, we’ll need dat a structures for the inventory file and for data flows between the I/O devices and the software. Note that system flow chart illustrates one possible solution; a good analyst will develop several feasible alternatives before choosing one.The flowchart maps the system, highlighting its major physical components. Since the data link the components, the next task is defining the data structures. Consider, for example, the inventory file. It contains all the data elements from the data store STOCK. The data el ements are listed in the data dictionary. Using them, the file’s data structure can be planned.How should the file be organized? That depends on how it will be accessed. For example, in some applications, data are processed at regular, predictable intervals. Typically, the data are collected over time and processed together, as a batch. If batch processing is acceptable, a sequential file organization is probably best.It is not always possible to wait until a batch of transactions is collected, however. For example, consider an air defense early warning system. If an unidentified aircraft is spotted, it must be identified immediately; the idea of waiting until 5:00 p. m because “that’s when the air defense program is run” is absurd. Instead, because of the need for quick response, each transaction must be processed as it occurs. Generally, such transaction processing systems call for direct access file.Our inventory system has tow programs. One processes transactions. A direct access inventory file seems a reasonable choice. The other allows management to study inventory data occasionally; batch processing would certainly do. Should the inventory file be organized sequentially or directly? Faced with such a choice, a good analyst considers both options. One possible system might accept transactions and process them as they occur. As an alternative, sales slips might be collected throughout the day and programs would deal with direct access files; in the second system, they would be linked to sequential files. A program to process direct access data is different from a program to process sequential data. The data drive the system. The choice of a data structure determines the program’s structure. Note that the program is defined and planned in the context of the system.ImplementationOnce the system’s major components have been identified, we can begin to develop them. Our system includes two programs, several pieces of equipment, and a number of data structures. During implementation, each program is planned and written using the techniques described in Chapter 7. Files are created, and their contents checked. New hardware is purchased, installed, and tested. Additionally, operating procedures are written and evaluated. Once all the component parts are ready, the system is tested. Assuming the user is satisfied, the finished system is released.SummaryA system is a collection of hardware, software, data, and procedural components that work together to accomplish an objective. A program is but one component in a system. System are planned and designed by system analysts who generally follow a well-defined,methodical process. The first step in the process is problem definition, when the analystattempts to discover exactly what the user needs. Often, following a preliminary problem definition, a feasibility study is conducted to determine if the problem can be solved. Given a clear problem definition, analysis begins. During this stage, the analyst develops a logical model of the system. Key functions are linked through a data flow diagram. Using the diagram as a tool, the data flows are traced, and the system’s data elements are identified and recorded in a data dictionary. After the logical system isreviewed with the user, design begins.During design, the analyst develops a model of the physical system. A system flowchart can be used to map the system, defining each physical component as a symbol. A good systems analyst considers a number of alternative solutions to the problem before settling on one. Implementation follows design. Programs are planned and written; hardware is ordered and installed; procedures are written; files and databases are initialized; and, finally, the pieces are assembled and tested. Following release of the system, maintenancebegins.学生信息管理系统的设计与发展随着信息技术的日新月异,各种管理系统的相继出现,让日常生活变的更加具有条理化, 尽可能的合理的运用网络资源可以大大的减少人工管理上带来的不便及时间的浪费.二十一世纪现代化程度的不断加速,科学文化水平的不断提高,学生数量的急剧增长，势必增加了管理学生信息带来的压力，人工检索的低效完全不符合整个社会的需要.学生信息管理系统是信息管理系统中的一种，目前信息技术不断的发展，网络技术已经广泛的应用于我们身边的各行各业，有了网络技术的发展，各高校都利用计算机来管理办学，以前学校靠手工操作的一切繁琐事情都得到了快速且高效率的解决，特别是学生成绩管理系统在学校中起到了很大的作用，对于学生和教师来说都能够更方便、快捷、准确地了解和管理各方面信息。

外文资料：Information management systemWiliam K.Thomson U.S.AAbstract:An information storage, searching and retrieval system for large (gigabytes) domains of archived textual dam. The system includes multiple query generation processes, a search process, and a presentation of search results that is sorted by category or type and that may be customized based on the professional discipline(or analogous personal characteristic of the user), thereby reducing the amount of time and cost required to retrieve relevant results.Keyword:Information management Retrieval system Object-Oriented1.INTRUDUCTIONThis invention relates to an information storage, searching and retrieval system that incorporates a novel organization for presentation of search results from large (gigabytes) domains of archived textual data.2.BACKGROUDN OF THE INVENTIONOn-line information retrieval systems are utilized for searching and retrieving many kinds of information. Most systems used today work in essentially the same manner; that is, users log on (through a computer terminal or personal microcomputer, and typically from a remote location), select a source of information (i.e., a particular database) which is usually something less than the complete domain, formulate a query, launch the search, and then review the search results displayed on the terminal or microcomputer, typically with documents (or summaries of documents) displayed in reverse chronological order. This process must be repeated each time another source (database) or group of sources is selected (which is frequently necessary in order to insure all relevant documents have been found).Additionally, this process places on the user the burden of organizing and assimilating the multiple results generated from the launch of the same query in each of the multiple sources(databases) that the user needs (or wants) to search. Present systems that allow searching of large domains require persons seeking information in these domains to attempt to modify their queries to reduce the search results to a size that the user can assimilate by browsing through them (thus, potentially eliminating relevant results).In many cases end users have been forced to use an intermediary (i.e., a professional searcher) because the current collections of sources are both complex and extensive, and effective search strategies often vary significantly from one source to another. Even with such guidance, potential relevant answers are missed because all potentially relevant databases or information sources are not searched on every query. Much effort has been expended on refining and improving source selection by grouping sources or database files together. Significant effort has also been expended on query formulation through the use of knowledge bases and natural language processing. However, as the groupings of sources become larger, and the responses to more comprehensive search queries become more complete, the person seeking information is often faced with the daunting task of sifting through large unorganized answer sets in an attempt to find the most relevant documents or information.3.SUMMARY OF THE INVENTIONThe invention provides an information storage, searching and retrieval system for a large domain of archived data of various types, in which the results of a search are organized into discrete types of documents and groups of document types so that users may easily identify relevant information more efficiently and more conveniently than systems currently in use. The system of the invention includes means for storing a large domain of data contained in multiple source records, at least some of the source records being comprised of individual documents of multiple document types; means for searching substantially all of the domain with a single search query to identify documents responsive to the query; and means for categorizing documents responsive to the query based on document type, including means for generating a summary of the number of documents responsive to the query which fall within various predetermined categories of document types.The query generation process may contain a knowledge base including a thesaurus that has predetermined and embedded complex search queries, or use natural language processing, or fuzzy logic, or tree structures, or hierarchical relationship or a set of commands that allow persons seeking information to formulate their queries.The search process can utilize any index and search engine techniques including Boolean, vector, and probabilistic as long as a substantial portion of the entire domain of archived textual data is searched for each query and all documents found are returned to the organizing process.The sorting/categorization process prepares the search results for presentation by assembling the various document types retrieved by the search engine and then arranging these basic document types into sometimes broader categories that are readily understood by and relevant to the user.The search results are then presented to the user and arranged by category along with an indication as to the number of relevant documents found in each category. The user may then examine search results in multiple formats, allowing the user to view as much of the document as the user deems necessary.4.BRIEF DESCRIPTION OF THE DRAWINGSFIG. 1 is a block diagram illustrating an information retrieval system of the invention;FIG. 2 is a diagram illustrating a query formulation and search process utilized in theinvention;FIG. 3 is a diagram illustrating a sorting process for organizing and presenting searchresults.5.BEST MODE FOR CARRYING OUT THE INVENTIONAs is illustrated in the block diagram of FIG. 1 , the information retrieval system of the invention includes an input/output process ,a query generation process, a search process that involves a large domain of textual data (typically in the multiple gigabyte range), an organizing process, presentation of the information to the user, and a process to identify and characterize the types of documents contained in the large domain of data.Turning now to FIG. 2, the query generation process preferably includes a knowledge base containing a thesaurus and a note pad, and preferably utilizes embedded predefined complex Boolean strategies. Such a system allows the user to enter their description of the information needed using simple words/phrases made up of "natural" language and to rely on the system to assist in generating the full search query, which would include, e.g., synonyms and alternate phraseology. The user can then request, by a command such as "VI CO 1", to view the complete documentselected from the list, giving, in this case, complete information about the identity and credentials of the expert.FIG. 3 illustrates how five typical sources of information (i.e., source records) can be sorted into many document types and then subsequently into categories. For example, a typical trade magazine may contain several types of information such as editorials, regular columns, feature articles, news, product announcements, and a calendar of events. Thus, the trade magazine (i.e., the source record) may be sorted into these various document types, and these document types in turn may be categorized or grouped into categories contained in one or more sets of categories; each document type typically will be sorted into one category within a set of categories, but the individual categories within each set will vary from one set to another. For example, one set of categories may be established for a first characteristic type of user, and a different set of categories may be established for a second characteristic type of user. When a user corresponding to type #1 executes a search, the system automatically utilizes the categories of set #1, corresponding to that particular type of user, in organizing the results of the search for review by the user. When a user from type #2 executes a search, however, the system automatically utilizes the categories of set #2 in presenting the search results to the user.The information storage, searching and retrieval system of the invention resolves the common difficulties in typical on-line information retrieval systems that operate on large (e.g., 2 gigabytes or more) domains of textual data, query generation, source selection, and organizing search results. The information base with the thesaurus and embedded search strategies allows users to generate expert search queries in their own "natural" language. Source (i.e., database) selection is not an issue because the search engines are capable of searching substantially the entire domain on every query. Moreover, the unique presentation of search results by category set substantially reduces the time and cost of performing repetitive searches in multiple databases and therefore of efficiently retrieving relevant search results.While a preferred embodiment of the present invention has been described, it should be understood that various changes, adaptations and modifications may bemade therein without departing from the spirit of the invention and the scope of the appended claims.中文译文：信息管理系统Wiliam K.Thomson U.S.A摘要：一个信息存储，查询和检索系统主要应用于大(千兆字节)的需要存档的文字领域。

英语专业资料Management Information System is that we often say that the MIS (Management Information System), emphasizing the management, stressed that the information in modern society it has become increasingly popular. MIS is a new subject, it across a number of areas, such as scientific management and system science, operations research, statistics and computer science. In these subjects on the basis of formation of information-gathering and processing methods, thereby forming a vertical and horizontal cutting system.Management information system of modern information management is an indispensable part of the work, is to meet modern standards of high-tech information management requirements, to promote scientific management, standardization of the necessary conditions. Only information practices, in order to offer better living environment and convenient living space.Information management is an extremely important resource, management depends on the success or failure of an effective decision-making, and the correct degree of decision-making depends largely on the quality of information.In the 21st century, mankind will enter the knowledge economy era, the era of knowledge economy is the rapid development of technology and knowledge, information was explosive expansion of the times. The threat of the so-called information that this is the human face to deal with the large amount of information it difficult to deal with the state, and cause confusion results.The emergence of a computer to solve this problem, because the computer quickly and accurately as information collection, processing, use,may be provided for.With computer technology, communications technology, network technology as the representative of modern information technology leap in development, human being from the industrial age into the information age, there is growing importance of information resources development and use of "information" has become a country Economic and social development of the key links, the level of information has become the level of a country's level of modernization and an important indicator of overall national strength.Management Information System is a computer and composed, to manage information collection, transmission, processing, preservation, maintenance and use of the system, it measured the national economy and enterprises, to help achieve its planned objectives.The development of computer-aided management has experienced four stages: transaction processing, handling systems to support decision-making, integrated services.In modern society, social trends and the expansion of social demand for our products so that enterprises in production and business activities relating to the expansion of the accumulation of internal and external information, with the rapid progress of science and technology and rapid development of production, so that human knowledge of the accelerating growth rate, the increase in the amount of information , Changes in the external environment becomes faster, artificial have not qualified. How to collect sufficient information resources, strong message and take advantage of the positive and timely development of effective use of information explosion of information resources has become a modern social problems. The emergence of a computer to solve this problem, because the computer quickly and accurately as information collection, processing, use, may be provided for. Computer technology and communications technologies with great modern information technology to promote the development of national information to speed up the process, the international community to build the information highway and an upsurge of Chinese workers, "the" famous works as the representative of national projects undertaken, so that China's Enterprise Information facing the new situation.Electronic computers adapt to modern society rapidly growing amount of information management, information life short, require timely conversion problem. Information systems from electronic data processing, information reporting system, decision support system to the further development of expert systems and support the leadership of the implementation of the decision-making process information in support of strategic decision-making competition in the strategic information systems. Today's society of modern information technology extensively to the rapid penetration of social life in various fields but in the management information system applications are still very imperfect, is the initial stage. Computer support for the work of the management, not only data processing, but also to support decision-making tools, from the mass of information collection, collation, analysis provided to managers, policy-related information, relevantpolicy analysis, and even managers Interactive dialogue to generate decision-making. At present the various sectors of the computer processing of information management, in large part are still individual business rationale, in the electronic data-processing stage, and units from transaction processing system to support system to deal with the real has also established a predictive control and support functions of management decision-making Information systems. Although the information system has a certain development, business process automation control office has made great progress, but far from perfect. Should make full use of the computer processing of information, we must start from the current situation, look to the future, the development of suitable units, a small industry management system, or even one-step, such as salary management system, and then gradually improve, and constantly expanded. Management Information System is one of the characteristics of centralized data, using the database. Use database technology to address data sharing issues. Database with a certain data model organization of data, data-oriented systems, procedures independent of the data, and data independence, to reduce data redundancy and inconsistency, and easy programming, expansion, removal. In particular, the 20th century the late 1970s distributed, in the face of object database, so that data and data from the operation as an object database management system to better use and reduce the possibility of problems. Attribute their inheritance in object share data And operation of great convenience to the users. All in all management information system is set scientific。

The Design and Development of the Students' Information Management SystemAs information technology advances, various management systems have emerged to change the daily lives of the more coherent, to the extent possible, the use of network resources can be significantly reasonable reduction of manual management inconvenience and waste of time.Accelerating the modernization of the 21st century, the continuous improvement of the scientific and cultural levels, the rapid growth of the number of students will inevitably increase the pressure information management students, the inefficient manual retrieval completely incompatible with the community\'s needs. The Student Information Management Systemis an information management one kind within system, currently information technique continuously of development, the network technique has already been applied in us extensively nearby of every trade, there is the network technical development, each high schools all make use of a calculator to manage to do to learn, the school is operated by handicraft before of the whole tedious affairs all got fast and solve high-efficiencily, especially student result management the system had in the school very big function, all can be more convenient, fast for the student and the teacher coming saying and understand accurately with management everyone noodles information. AbstractIt is a very heavy and baldness job of managing a bulky database by manpower. The disadvantage, such as great capacity of work, low efficiency and long period, exist in data inputting, demanding and modification. So the computer management system will bring us a quite change.Because there are so many students in the school, the data of students' information is huge, it makes the management of the information become a complicated and tedious work. This system aims at the school, passing by practically of demand analysis, adopt mighty VB6.0 to develop the student information managementsystem. The whole system design process follow the principle of simple operation, beautiful and vivid interface and practical request. The student information management system including the function of system management, basic information management, study management, prize and punishment management , print statement and so on. Through the proof of using, the student information management system which this text designed can satisfy the school to manage the demand of the aspect to students' information. The thesis introduced the background of development, the functions demanded and the process of design. The thesis mainly explained the point of the system design, the thought of design, the difficult technique and the solutions. The student managed the creation of the system to reduce the inconvenience on the manpower consumedly, let the whole student the data management is more science reasonable.The place that this system has most the special features is the backstage database to unify the management to student's information.That system mainly is divided into the system management, student profession management, student file management, school fees management, course management, result management and print the statement.The interface of the system is to make use of the vb software creation of, above few molds pieces are all make use of the vb to control a the piece binds to settle of method to carry out the conjunction toward the backstage database, the backstage database probably is divided into following few formses:Professional information form, the charges category form, student the job form, student the information form, political feature form of student, the customer logs on the form The system used Client/Server structure design, the system is in the data from one server and a number of Taiwan formed LAN workstations. Users can check the competence of different systems in different users submit personal data, background database you can quickly given the mandate to see to the content.Marks management is a important work of school,the original manual management havemany insufficiencies,the reasons that,students' population are multitudinous in school,and each student's information are too complex,thus the work load are extremely big,the statistics and the inquiry have been inconvenient.Therefore,how to solve these insufficiencies,let the marks management to be more convenient and quickly,have a higher efficiency,and become a key question.More and more are also urgent along with school automationthe marks management when science and technology rapid development,therefore is essential to develop the software system of marks register to assist the school teaching management.So that can improve the marks management,enhance the efficiency of management.Systems Analysis and Design SystemsWorking under control of a stored program, a computer processes data into information. Think about that definition for a minute. Any given computer application involves at least three components: hardware, software, and data. Merely writing a program isn’t enough, because the program is but one component is in a system.A system is a group of components that work together to accomplish an objective. For example, consider a payroll system. Its objective is paying employees. What components are involved? Each day, employees record their hours worked on time cards. At the end of each week, the time cards are collected and delivered to the computer center, where they are read into a payroll program. As it runs, the program accesses data files. Finally, the paychecks are printed and distributed. For the system to work, people, procedures, input and output media, files, hardware, and software must be carefully coordinated. Note that the program is but one component in a system.Systems AnalysisComputer-based systems are developed because people need information. Those people,called users, generally know what is required, but may lack the expertise to obtain it. Technical professionals, such as programmers, have the expertise, but may lack training in the user’s field. To complicate matters, users an d programmers often seem to speak different languages, leading to communication problems. A systems analyst is a professional who translates user needs into technical terms, thus serving as a bridge between users and technical professionals.Like an engineer or an architect, a systems analyst solves problems by combining solid technical skills with insight, imagination, and a touch of art. Generally, the analyst follows a well-defined, methodical process that includes at least the following steps: Problem definitionAnalysisDesignImplementationMaintenanceAt the end of each step, results are documented and shared with both the user and the programmers. The idea is to catch and correct errors and misunderstandings as early as possible. Perhaps the best way to illustrate the process is through example.Picture a small clothing store that purchases merchandise at wholesale, displays this stock, and sells it to customers at retail. On the one hand, too much: stock represents an unnecessary expense. On the other hand, a poor selection discourages shoppers. Ideally, a balance can be achieved: enough, but not too much.Complicating matters is the fact that inventory is constantly changing, with customer purchases depleting stock, and returns and reorders adding to it. The owner would like to track inventory levels and reorder any given item just before the store runs out. For a single item, the task is easy-just count the stock-on-hand. Unfortunately, the store has hundreds of different items, and keeping track of each one is impractical. Perhaps a computer might help.Problem DefinitionThe first step in the systems analysis and design process is problem definition. Theanalyst’s objective is determining what the user needs. Note that, as the process begins, the user possesses the critical information, and the analyst must listen and learn. Few users are technical experts. Most see the computer as a “magic box,” and are not concerned with how it works. At this stage, the analyst has no business even thinking about programs, files, and computer hardware, but must communicate with the user on his or her own terms.The idea is to ensure that both the user and the analyst are thinking about the same thing. Thus, a clear, written statement expressing the analyst’s underst anding of the problem is essential. The user should review and correct this written statement. The time to catch misunderstandings and oversights is now, before time, money, and effort are wasted. Often, following a preliminary problem definition, the analyst performs a feasibility study. The study, a brief capsule version of the entire systems analysis and design process, attempts to answer three questions:1.Can the problem be solved?2.Can it be solved in the user’s environment?3.Can it be solved at a reasonable cost?If the answer to any one of these questions is no, the system should not be developed. Given a good problem definition and a positive feasibility study, the analyst can turn to planning and developing a problem solution.AnalysisAs analysis begins, the analyst understands the problem. The next step is determining what must be done to solve it. The user knows what must be done; during analysis, this knowledge is extracted and formally documented. Most users think in terms of the functions to be performed and the data elements to be manipulated. The objective is to identify and link these key functions and data elements, yielding a logical system design. Start with the system’s basic functions. The key is keeping track of the stock-on-hand for each product in inventory. Inventory changes because customers purchase, exchange, and return products, so the system will have to process customer transactions. The store’s owner wants to selectively look at the inventory level for any product in short supply and,if appropriate, order replacement stock, so the system must be able to communicate with management. Finally, following management authorization, the system should generate a reorder ready to send to a supplier.Given the system’s basic functions, the analyst’s next task is gaining a sense of their logical relation. A good way to start is by describing how data flow between the functions. As the name implies, data flow diagrams are particularly useful for graphically describing these data flows. Four symbols are used. Data sources and destinations are represented by squares; input data enter the system form a source, and output data flow to a destination. Once in the system, the data are manipulated or changed by processes, represented by round-corner rectangles. A process might be a program, a procedure, or anything else that changes or moves data. Data can be held for later processing in data stores, symbolized by open-ended rectangles. A data store might be a disk file, a tape file, a database, written notes, or even a person’s memory. Finally, data flow between sources, destinations, processes, and data stores over data flows, which are represented by arrows. Preliminary data flow diagram for the inventory system. Start a CUSTOMER. Transactions flow from a customer into the system, where they are handled by Process transaction. A data store, the STOCK, holds data on each item in inventory. Process transaction changes the data to reflect the new transaction. Meanwhile, MANAGEMENT accesses the system through Communicate, evaluating the data in STOCK and, if necessary, requesting a recorder. Once a reorder is authorized, Generate reorder sends necessary data to the SUPPLIER, who ships the items to the store. Note that, because the reorder represents a change in the inventory level of a particular product or products, it is handled as a transaction.The data flow diagram describes the logical system. The next step is tracing the data flow. Start with the destination SUPPLIER. Reorders flow to suppliers; for example, the store might want 25 pairs of jeans. To fill the order, the supplier needs the product description and the reorder quantity. Where do these data elements come from? Since they are output by Generate reorder, they must either be input to or generated by this process. Data flow into Generate reorder for STOCK; thus, product and reorder quantities must be stored inSTOCK.Other data elements, such as purchased and the purchase quantity, are generated by CUSTOMER. Still others, for example selling price and reorder point, are generated by or needed by MANAGEMENT. The current stock –on-hand for a given item is an example of a data element generated by an algorithm in one of the procedures. Step by step, methodically, the analyst identifies the data elements to be input to, stored by, manipulated by, generated by, or output by the system.To keep track of the data elements, the analyst might list each one in a data dictionary. A simple data dictionary can be set up on index cards, but computerized data dictionaries have become increasingly popular. The data dictionary, a collection of data describing and defining the data, is useful throughout the systems analysis and design process, and is often used to build a database during the implementation stage.The idea of analysis is to define the system’s major functions and data elements methodically. Remember that the objective is translating user needs into technical terms. Since the system starts with the user, the first step is defi ning the user’s needs. Users think in terms of functions and data. They do not visualize programs, or files, or hardware, and during this initial, crucial analysis stage, it is essential that the analyst think like a user, not like a programmer.Data flow diagrams and data dictionaries are useful tools. They provide a format for recording key information about the proposed system. Also, they jog the analyst’s memory; for example, if the analyst doesn’t have sufficient information to complete a data dictionary entry, he or she has probably missed something. Perhaps most importantly, the data flow diagram and the data dictionary document the analyst’s understanding of the system requirements. By reviewing these documents, the user can correct misunderstanding or oversights. Finally, they represent an excellent starting point for the next step, design.DesignAs we enter the design stage, we know what the system must do, and thus can begin thinking about how to do it. The objective is to develop a strategy for solving the problem.At this stage, we are not interested in writing code or in defining precise data structures; instead, we want to identify, at a black box level, necessary programs, files, procedures, and other components.The data flow diagram defines the system’s necessary functions; how might they be implemented? One possibility is writing one program for each process. Another is combining two or more processes in a single program; there are dozens of alternative solutions. Let’s focus on one option a nd document it.A system flowchart uses symbols to represent programs, procedures, hardware devices, and the other components of a physical system. Our flowchart shows that transaction data enter the system through a terminal, are stored on an inventory by a data collection program, and then are stored on an inventory file. Eventually, the inventory file is processed by a Report and reorder program. Through it, management manipulates the data and authorizes reorders.Look at the system flowchart. It identifies several hardware components, including a computer, a disk drive, a data entry terminal, a printer, and a display terminal. Tow programs are needed: Process transaction and Report and reorder. In addition to the hardware and the programs, we’ll need dat a structures for the inventory file and for data flows between the I/O devices and the software. Note that system flow chart illustrates one possible solution; a good analyst will develop several feasible alternatives before choosing one.The flowchart maps the system, highlighting its major physical components. Since the data link the components, the next task is defining the data structures. Consider, for example, the inventory file. It contains all the data elements from the data store STOCK. The data el ements are listed in the data dictionary. Using them, the file’s data structure can be planned.How should the file be organized? That depends on how it will be accessed. For example, in some applications, data are processed at regular, predictable intervals. Typically, the data are collected over time and processed together, as a batch. If batch processing is acceptable, a sequential file organization is probably best.It is not always possible to wait until a batch of transactions is collected, however. For example, consider an air defense early warning system. If an unidentified aircraft is spotted, it must be identified immediately; the idea of waiting until 5:00 p. m because “that’s when the air defense program is run” is absurd. Instead, because of the need for quick response, each transaction must be processed as it occurs. Generally, such transaction processing systems call for direct access file.Our inventory system has tow programs. One processes transactions. A direct access inventory file seems a reasonable choice. The other allows management to study inventory data occasionally; batch processing would certainly do. Should the inventory file be organized sequentially or directly? Faced with such a choice, a good analyst considers both options. One possible system might accept transactions and process them as they occur. As an alternative, sales slips might be collected throughout the day and programs would deal with direct access files; in the second system, they would be linked to sequential files. A program to process direct access data is different from a program to process sequential data. The data drive the system. The choice of a data structure determines the program’s structure. Note that the program is defined and planned in the context of the system.ImplementationOnce the system’s major components have been identified, we can begin to develop them. Our system includes two programs, several pieces of equipment, and a number of data structures. During implementation, each program is planned and written using the techniques described in Chapter 7. Files are created, and their contents checked. New hardware is purchased, installed, and tested. Additionally, operating procedures are written and evaluated. Once all the component parts are ready, the system is tested. Assuming the user is satisfied, the finished system is released.SummaryA system is a collection of hardware, software, data, and procedural components that work together to accomplish an objective. A program is but one component in a system. System are planned and designed by system analysts who generally follow a well-defined,methodical process. The first step in the process is problem definition, when the analystattempts to discover exactly what the user needs. Often, following a preliminary problem definition, a feasibility study is conducted to determine if the problem can be solved. Given a clear problem definition, analysis begins. During this stage, the analyst develops a logical model of the system. Key functions are linked through a data flow diagram. Using the diagram as a tool, the data flows are traced, and the system’s data elements are identified and recorded in a data dictionary. After the logical system isreviewed with the user, design begins.During design, the analyst develops a model of the physical system. A system flowchart can be used to map the system, defining each physical component as a symbol. A good systems analyst considers a number of alternative solutions to the problem before settling on one. Implementation follows design. Programs are planned and written; hardware is ordered and installed; procedures are written; files and databases are initialized; and, finally, the pieces are assembled and tested. Following release of the system, maintenancebegins.学生信息管理系统的设计与发展随着信息技术的日新月异,各种管理系统的相继出现,让日常生活变的更加具有条理化, 尽可能的合理的运用网络资源可以大大的减少人工管理上带来的不便及时间的浪费.二十一世纪现代化程度的不断加速,科学文化水平的不断提高,学生数量的急剧增长，势必增加了管理学生信息带来的压力，人工检索的低效完全不符合整个社会的需要.学生信息管理系统是信息管理系统中的一种，目前信息技术不断的发展，网络技术已经广泛的应用于我们身边的各行各业，有了网络技术的发展，各高校都利用计算机来管理办学，以前学校靠手工操作的一切繁琐事情都得到了快速且高效率的解决，特别是学生成绩管理系统在学校中起到了很大的作用，对于学生和教师来说都能够更方便、快捷、准确地了解和管理各方面信息。
