Computer Program1IntroductionComputer Program, set of instructions that directs a computer to perform some processing function or combination of functions. For the instructions to be carried out, a computer must execute a program, that is, the computer reads the program, and then follow the steps encoded in the program in a precise order until completion. A program can be executed many different times, with each execution yielding a potentially different result depending upon the options and data that the user gives the computer.Programs fall into two major classes: application programs and operating systems. An application program is one that carries out some function directly for a user, such as word processing or game-playing. An operating system is a program that manages the computer and the various resources and devices connected to it, such as RAM, hard drives, monitors, keyboards, printers, and modems, so that they may be used by other programs. Examples of operating systems are DOS, Windows 95, OS\2, and UNIX.2Program DevelopmentSoftware designers create new programs by using special applications programs, often called utility programs ordevelopment programs. A programmer uses another type of program called a text editor to write the new program in a special notation called a programming language. With the text editor, the programmer creates a text file, which is an ordered list of instructions, also called the program source file. The individual instructions that make up the program source file are called source code. At this point, a special applications program translates the source code into machine language, or object code—a format that the operating system will recognize as a proper program and be able to execute.Three types of applications programs translate from source code to object code: compilers, interpreters, and assemblers. The three operate differently and on different types of programming languages, but they serve the same purpose of translating from a programming language into machine language.A compiler translates text files written in a high-level programming language--such as FORTRAN, C, or Pascal—from the source code to the object code all at once. This differs from the approach taken by interpreted languages such as BASIC, APL and LISP, in which a program is translated into object code statement by statement as each instruction is executed. The advantage to interpreted languages is that they can beginexecuting the program immediately instead of having to wait for all of the source code to be compiled. Changes can also be made to the program fairly quickly without having to wait for it to be compiled again. The disadvantage of interpreted languages is that they are slow to execute, since the entire program must be translated one instruction at a time, each time the program is run. On the other hand, compiled languages are compiled only once and thus can be executed by the computer much more quickly than interpreted languages. For this reason, compiled languages are more common and are almost always used in professional and scientific applications.Another type of translator is the assembler, which is used for programs or parts of programs written in assembly language. Assembly language is another programming language, but it is much more similar to machine language than other types of high-level languages. In assembly language, a single statement can usually be translated into a single instruction of machine language. Today, assembly language is rarely used to write an entire program, but is instead most often used when the programmer needs to directly control some aspect of the computer’s function.Programs are often written as a set of smaller pieces, with eachpiece representing some aspect of the overall application program. After each piece has been compiled separately, a program called a linker combines all of the translated pieces into a single executable program.Programs seldom work correctly the first time, so a program called a debugger is often used to help find problems called bugs. Debugging programs usually detect an event in the executing program and point the programmer back to the origin of the event in the program code.Recent programming systems, such as Java, use a combination of approaches to create and execute programs. A compiler takes a Java source program and translates it into an intermediate form. Such intermediate programs are then transferred over the Internet into computers where an interpreter program then executes the intermediate form as an application program.3Program ElementsMost programs are built from just a few kinds of steps that are repeated many times in different contexts and in different combinations throughout the program. The most common step performs some computation, and then proceeds to the next step in the program, in the order specified by the programmer. Programs often need to repeat a short series of steps many times,for instance in looking through a list of game scores and finding the highest score. Such repetitive sequences of code are called loops.One of the capabilities that makes computer so useful is their ability to make conditional decisions and perform different instructions based on the values of data being processed. If-then-else statements implement this function by testing some piece of data and then selecting one of two sequences of instructions on the basis of the result. One of the instructions in these alternatives may be a goto statement that directs the computer to select its next instruction from a different part of the program. For example, a program might compare two numbers and branch to a different part of the program depending on the result of the comparison:If x is greater than yThenGoto instruction # 10Else continueProgram often use a specific sequence of steps more than once. Such a sequence of steps can be grouped together into a subroutine, which can then be called, or accessed, as needed in different parts of the main program. Each time a subroutineis called, the computer remembers where it was in the program when the call was made, so that it can return there upon completion of the subroutine, allowing a very general piece of code to be written once and used in multiple ways.Most programs use several varieties of subroutines. The most common of these are functions, procedures, library routines, system routines, and device drivers. Functions are short subroutines that compute some value, such as computations of angles, which the computer cannot compute with a single basic instruction. Procedures perform a more complex function, such as sorting a set of names. Library routines are subroutines that are written for use by many different programs. System routines are similar to library routines but are actually found in the operating system. They provide some service for the application programs, such as printing a line of text. Device drivers are system routines that are added to an operating system to allow the computer to communicate with a new device, such as a scanner, modem, or printer. Device drivers often have features that can be executed directly as applications programs. This allows the user to directly control the device, which is useful if, for instance, a color printer needs to be realigned to attain the best printing quality after changing an ink cartridge.4Program FunctionModern computers usually store programs on some form of magnetic storage media that can be accessed randomly by the computer, such as the hard drive disk permanently located in the computer, or a portable floppy disk. Additional information on such disks, called directories, indicate the names of the various program begins on the disk media. When a user directs the computer to execute a particular application program, the operating system looks through these directories, locates the program, and reads a copy into RAM. The operating system then directs the CPU to start executing the instructions at the beginning of the program. Instructions at the beginning of the program prepare the computer to process information by locating free memory locations in RAM to hold working data, retrieving copies of the standard options and defaults the user has indicated from a disk, and drawing initial displays on the monitor.The application program requests copy of any information the user enters by making a call to a system routine. The operating system converts any data so entered into a standard internal form. The application then uses this information to decide what to do next---for example, perform some desired processingfunction such as reformatting a page of text, or obtain some additional information from another file on a disk. In either case, calls to other system routines are used to actually carry out the display of the results or the accessing of the file from the disk.When the application reaches completion or is prompted to quit, it makes further system calls to make sure that all data that needs to be saved has been written back to disk. It then makes a final system call to the operating system indicating that it is finished. The operating system then frees up the RAM and any device that the application was using and awaits a command from the user to start another program.5 HistoryPeople have been storing sequences of instructions in the form of a program for several centuries. Music boxes of the 18th century and player pianos of the late 19th and early 20th centuries played musical programs stored as series if metal pins, or holes in paper, with each line representing when a note was to be played, and the pin or hole indicating what note was to be played at that time. More elaborate control of physical devices became common in the early 1800s with French inventor Joseph Marie Jacquard’s invention of the punch-cardcontrolled weaving loom. In the process of weaving a particular pattern, various parts of the loom had to be mechanically positioned. To automate this process, Jacquard used a single paper card to represent each positioning of the loom, with hole in the card to indicate which loom actions should be done. An entire tapestry could be encoded onto a deck of such cards, with the same deck yielding the same tapestry design each time it was used. Programs of over 24,000 card were developed and used. The world’s first programmable machine was designed---although never fully built---by the English mathematician and inventor, Charles Babbage. This machine, called the Analytical Engine, used punch cards similar to those used in the Jacquard loom to select the specific arithmetic operation to apply at each step. Inserting a different set of cards changed the computations the machine performed. This machine had counterparts for almost everything found in modern computers, although it was mechanical rather than electrical. Construction of the Analytical Engine was never completed because the technology required to build it did not exist at the time.The first card deck programs for the Analytical Engine were developed by British mathematician Countess Augusta AdaLovelace, daughter of the poet Lord Byron. For this reason she is recognized as the world’s first programmer.The modern concept of an internally stored computer program was first proposed by Hungarian-American mathematician John von Neumann in 1945. Von Neumann’s idea was to use the computer’s memory to store the program as well as the data. In this way, programs can be viewed as data and can be processed like data by other programs. This idea greatly simplifies the role of program storage and execution in computers.6 The FutureThe field of computer science has grown rapidly since the 1950s due to the increase in their use. Computer programs have undergone many changes during this time in response to user need and advances in technology. Newer ideas in computing such as parallel computing, distributed computing, and artificial intelligence, have radically altered the traditional concepts that once determined program form and function.Computer scientists working in the field of parallel computing, in which multiple CPUs cooperate on the same problem at the same time, have introduced a number of new program models. In parallel computing parts of a problem are worked on simultaneously by different processors, and this speeds up thesolution of the problem. Many challenges face scientists and engineers who design programs for parallel processing computers, because of the extreme complexity of the systems and the difficulty involved in making them operate as effectively as possible.Another type of parallel computing called distributed computing uses CPUs from many interconnected computers to solve problems. Often the computers used to process information in a distributed computing application are connected over the Internet. Internet applications are becoming a particularly useful form of distributed computing, especially with programming languages such as Java. In such applications, a user logs onto a web site and downloads a Java program onto their computer. When the Java program is run, it communicates with other programs at its home Web site, and may also communicate with other programs running on different computers or Web sites.Research into artificial intelligence has led to several other new styles of programming. Logic programs, for example, do not consist of individual instructions for the computer to follow blindly, but instead consist of sets of rules: if x happens then do y. A special program called an inference engine uses theserules to “reason”its way to a conclusion when presented with a new problem. Applications of logic programs include automatic monitoring of complex systems, and proving mathematical theorems.A radically different approach to computing in which there is no program in the conventional sense is called a neural network.A neural network is a group of highly interconnected simple processing elements, designed to mimic the brain. Instead of having a program direct the information processing in the way that a traditional computer does, a neural network processes information depending upon the way that its processing elements are connected. Programming a neural network is accomplished by presenting it with known patterns of input and output data and adjusting the relative importance of the interconnections between the processing elements until the desired pattern matching is accomplished. Neural networks are usually simulated on traditional computers, but unlike traditional computer programs, neural networks are able to learn from their experience.。

Computer Program1IntroductionComputer Program, set of instructions that directs a computer to perform some processing function or combination of functions. For the instructions to be carried out, a computer must execute a program, that is, the computer reads the program, and then follow the steps encoded in the program in a precise order until completion. A program can be executed many different times, with each execution yielding a potentially different result depending upon the options and data that the user gives the computer.Programs fall into two major classes: application programs and operating systems. An application program is one that carries out some function directly for a user, such as word processing or game-playing. An operating system is a program that manages the computer and the various resources and devices connected to it, such as RAM, hard drives, monitors, keyboards, printers, and modems, so that they may be used by other programs. Examples of operating systems are DOS, Windows 95, OS\2, and UNIX.2Program DevelopmentSoftware designers create new programs by using special applications programs, often called utility programs ordevelopment programs. A programmer uses another type of program called a text editor to write the new program in a special notation called a programming language. With the text editor, the programmer creates a text file, which is an ordered list of instructions, also called the program source file. The individual instructions that make up the program source file are called source code. At this point, a special applications program translates the source code into machine language, or object code—a format that the operating system will recognize as a proper program and be able to execute.Three types of applications programs translate from source code to object code: compilers, interpreters, and assemblers. The three operate differently and on different types of programming languages, but they serve the same purpose of translating from a programming language into machine language.A compiler translates text files written in a high-level programming language--such as FORTRAN, C, or Pascal—from the source code to the object code all at once. This differs from the approach taken by interpreted languages such as BASIC, APL and LISP, in which a program is translated into object code statement by statement as each instruction is executed. The advantage to interpreted languages is that they can beginexecuting the program immediately instead of having to wait for all of the source code to be compiled. Changes can also be made to the program fairly quickly without having to wait for it to be compiled again. The disadvantage of interpreted languages is that they are slow to execute, since the entire program must be translated one instruction at a time, each time the program is run. On the other hand, compiled languages are compiled only once and thus can be executed by the computer much more quickly than interpreted languages. For this reason, compiled languages are more common and are almost always used in professional and scientific applications.Another type of translator is the assembler, which is used for programs or parts of programs written in assembly language. Assembly language is another programming language, but it is much more similar to machine language than other types of high-level languages. In assembly language, a single statement can usually be translated into a single instruction of machine language. Today, assembly language is rarely used to write an entire program, but is instead most often used when the programmer needs to directly control some aspect of the computer’s function.Programs are often written as a set of smaller pieces, with eachpiece representing some aspect of the overall application program. After each piece has been compiled separately, a program called a linker combines all of the translated pieces into a single executable program.Programs seldom work correctly the first time, so a program called a debugger is often used to help find problems called bugs. Debugging programs usually detect an event in the executing program and point the programmer back to the origin of the event in the program code.Recent programming systems, such as Java, use a combination of approaches to create and execute programs. A compiler takes a Java source program and translates it into an intermediate form. Such intermediate programs are then transferred over the Internet into computers where an interpreter program then executes the intermediate form as an application program.3Program ElementsMost programs are built from just a few kinds of steps that are repeated many times in different contexts and in different combinations throughout the program. The most common step performs some computation, and then proceeds to the next step in the program, in the order specified by the programmer. Programs often need to repeat a short series of steps many times,for instance in looking through a list of game scores and finding the highest score. Such repetitive sequences of code are called loops.One of the capabilities that makes computer so useful is their ability to make conditional decisions and perform different instructions based on the values of data being processed. If-then-else statements implement this function by testing some piece of data and then selecting one of two sequences of instructions on the basis of the result. One of the instructions in these alternatives may be a goto statement that directs the computer to select its next instruction from a different part of the program. For example, a program might compare two numbers and branch to a different part of the program depending on the result of the comparison:If x is greater than yThenGoto instruction # 10Else continueProgram often use a specific sequence of steps more than once. Such a sequence of steps can be grouped together into a subroutine, which can then be called, or accessed, as needed in different parts of the main program. Each time a subroutineis called, the computer remembers where it was in the program when the call was made, so that it can return there upon completion of the subroutine, allowing a very general piece of code to be written once and used in multiple ways.Most programs use several varieties of subroutines. The most common of these are functions, procedures, library routines, system routines, and device drivers. Functions are short subroutines that compute some value, such as computations of angles, which the computer cannot compute with a single basic instruction. Procedures perform a more complex function, such as sorting a set of names. Library routines are subroutines that are written for use by many different programs. System routines are similar to library routines but are actually found in the operating system. They provide some service for the application programs, such as printing a line of text. Device drivers are system routines that are added to an operating system to allow the computer to communicate with a new device, such as a scanner, modem, or printer. Device drivers often have features that can be executed directly as applications programs. This allows the user to directly control the device, which is useful if, for instance, a color printer needs to be realigned to attain the best printing quality after changing an ink cartridge.4Program FunctionModern computers usually store programs on some form of magnetic storage media that can be accessed randomly by the computer, such as the hard drive disk permanently located in the computer, or a portable floppy disk. Additional information on such disks, called directories, indicate the names of the various program begins on the disk media. When a user directs the computer to execute a particular application program, the operating system looks through these directories, locates the program, and reads a copy into RAM. The operating system then directs the CPU to start executing the instructions at the beginning of the program. Instructions at the beginning of the program prepare the computer to process information by locating free memory locations in RAM to hold working data, retrieving copies of the standard options and defaults the user has indicated from a disk, and drawing initial displays on the monitor.The application program requests copy of any information the user enters by making a call to a system routine. The operating system converts any data so entered into a standard internal form. The application then uses this information to decide what to do next---for example, perform some desired processingfunction such as reformatting a page of text, or obtain some additional information from another file on a disk. In either case, calls to other system routines are used to actually carry out the display of the results or the accessing of the file from the disk.When the application reaches completion or is prompted to quit, it makes further system calls to make sure that all data that needs to be saved has been written back to disk. It then makes a final system call to the operating system indicating that it is finished. The operating system then frees up the RAM and any device that the application was using and awaits a command from the user to start another program.5 HistoryPeople have been storing sequences of instructions in the form of a program for several centuries. Music boxes of the 18th century and player pianos of the late 19th and early 20th centuries played musical programs stored as series if metal pins, or holes in paper, with each line representing when a note was to be played, and the pin or hole indicating what note was to be played at that time. More elaborate control of physical devices became common in the early 1800s with French inventor Joseph Marie Jacquard’s invention of the punch-cardcontrolled weaving loom. In the process of weaving a particular pattern, various parts of the loom had to be mechanically positioned. To automate this process, Jacquard used a single paper card to represent each positioning of the loom, with hole in the card to indicate which loom actions should be done. An entire tapestry could be encoded onto a deck of such cards, with the same deck yielding the same tapestry design each time it was used. Programs of over 24,000 card were developed and used. The world’s first programmable machine was designed---although never fully built---by the English mathematician and inventor, Charles Babbage. This machine, called the Analytical Engine, used punch cards similar to those used in the Jacquard loom to select the specific arithmetic operation to apply at each step. Inserting a different set of cards changed the computations the machine performed. This machine had counterparts for almost everything found in modern computers, although it was mechanical rather than electrical. Construction of the Analytical Engine was never completed because the technology required to build it did not exist at the time.The first card deck programs for the Analytical Engine were developed by British mathematician Countess Augusta AdaLovelace, daughter of the poet Lord Byron. For this reason she is recognized as the world’s first programmer.The modern concept of an internally stored computer program was first proposed by Hungarian-American mathematician John von Neumann in 1945. Von Neumann’s idea was to use the computer’s memory to store the program as well as the data. In this way, programs can be viewed as data and can be processed like data by other programs. This idea greatly simplifies the role of program storage and execution in computers.6 The FutureThe field of computer science has grown rapidly since the 1950s due to the increase in their use. Computer programs have undergone many changes during this time in response to user need and advances in technology. Newer ideas in computing such as parallel computing, distributed computing, and artificial intelligence, have radically altered the traditional concepts that once determined program form and function.Computer scientists working in the field of parallel computing, in which multiple CPUs cooperate on the same problem at the same time, have introduced a number of new program models. In parallel computing parts of a problem are worked on simultaneously by different processors, and this speeds up thesolution of the problem. Many challenges face scientists and engineers who design programs for parallel processing computers, because of the extreme complexity of the systems and the difficulty involved in making them operate as effectively as possible.Another type of parallel computing called distributed computing uses CPUs from many interconnected computers to solve problems. Often the computers used to process information in a distributed computing application are connected over the Internet. Internet applications are becoming a particularly useful form of distributed computing, especially with programming languages such as Java. In such applications, a user logs onto a web site and downloads a Java program onto their computer. When the Java program is run, it communicates with other programs at its home Web site, and may also communicate with other programs running on different computers or Web sites.Research into artificial intelligence has led to several other new styles of programming. Logic programs, for example, do not consist of individual instructions for the computer to follow blindly, but instead consist of sets of rules: if x happens then do y. A special program called an inference engine uses theserules to “reason”its way to a conclusion when presented with a new problem. Applications of logic programs include automatic monitoring of complex systems, and proving mathematical theorems.A radically different approach to computing in which there is no program in the conventional sense is called a neural network.A neural network is a group of highly interconnected simple processing elements, designed to mimic the brain. Instead of having a program direct the information processing in the way that a traditional computer does, a neural network processes information depending upon the way that its processing elements are connected. Programming a neural network is accomplished by presenting it with known patterns of input and output data and adjusting the relative importance of the interconnections between the processing elements until the desired pattern matching is accomplished. Neural networks are usually simulated on traditional computers, but unlike traditional computer programs, neural networks are able to learn from their experience.。

computer--外文翻译

Classification of computerComputer can be placed in to three general classes: mainframes, minicomputers and microcomputers. These classifications are usually based on three characteristics of computers: speed, main-storage, capacity and word size. Speed is expressed by how many millions of instructions. Can be executed per second, called MIPS. Main-storage capacity is the number of characters a computer’s memory can hold, word size is the number of bits in an Main storage location, the amount of main-stora ge that can be addressed is partly determined by a computer’s word size.Mini computerA typical minicomputer has a 16-to 64-bit word size. Its main storage capacity ranges from 8 bytes to 16 megabytes. Clearly the character is tics of minicomputer systems vary widely. Character of some computer equal thus of mainframes. A minicomputer system usually in clouds a display screen. Printer and magnetic .The development of the microcomputer begin in 1971 with the introduction of the first computer processor based on electronics. Since that time there have been a number of improvements in the computer, and the microcomputer has had a tremendous impact on the computer industry. Beside size, it is primary advantage is low cost. Most microprocessors have either a 16-bit or 32- bit word size. Typical microcomputer main storage capacities rage from 1M to 8M characters.Mainframes can be super computers, lager computers or small computers. The term main frame refers to computers systems. Provided by the major computer vendors, Such as IBM. The most powerful mainframes are called super computers. They can execute hundreds of millions of instructions pre second, have up to a 128-bit word size and may have a main-storage capacity of over 200 million characters. Super computers are used primarily in scientific applications requiring extensive calculations.Large computerLarge computer systems can execute 50 to 150 million instruction 5 per second, commonly have a 64-or 128-bitwordsize, and have a main-storage capacity of up to 128 million characters. Like other mainframes, these machines can be expanded to provide additional processing capability. A typical large computer system may include: 32 million characters of mainstorage.10 to 50 billion characters of fixed-disk second. Several high-speed line printers and a lower page printer.100 to 200 terminal .If a mainframe is not a large computer its characteristics are more differ to distinguish. We shall group all such mainframes into the class of smaller computers. These smaller computers may execute 10 to 50 million instructions per second. Some have the same word size as large computers.Microprocessor applicationsLet us begin our discussion by talking a brief look at some of the endless applications that are being implemented with MP systems. We will list major fields and then some representative applications within each field.1.Word-processing machines that allow the operator to type letters. Forms, and the like, to add,delete, or alter and selected items, and finally to print the edited version onto standard paper.2.Smart writers that have enough memory to hold a number of forms or letters. After a pertlyletter is selected, the MP prints it out on typing paper much faster and certainly with less fatigue than a typist. It can pause at certain key areas and allow the operator to enter specific information such as name and address.3.Small-business computer systems that perform all the operations normally associated withfull-size computers. They routinely handle payroll, accounts receivable, account, payable, general ledger, and inventory control.Consumer1 Automobiles ignition system controllers the can monitor several parameters and continuously adjust the ignition system to provide optimum efficiency.The same MP may also have time to perform self, monitoring and display of engine parameters, and an array of other helpful tasks.2. Electronic games are typically up based. They range in complexity from the arcade involving a real-time display of competition between several players to the less sophisticated hand-held types.4.Environmental control systems are now a feasible option for the owner. It is well within asingle MP’s capability to the temperature in various rooms and control them individually to conform to the owner’s pre ferences. The same device would have plenty of time to provide, protection for burglars, fire, and the like, and still be able to help the kids with their multiplication tables.Computer hobbyists1.The home computer is rapidly becoming standard equipment for family. The duties assignedto this newest family member vary from income tax assistance to providing challenging games that match the players’ skill against the apparent intelligence of the computer.2.Many hobbyists, particularly ham radio operate are home computers to track satellites andeven control antennas so as to maintain optimum communications at all times.3.Some computer enthusiasts are turning their in tests into a substantial second income: Some ofthese ideas include maintaining bowling for local leagues, generating monthly mailing lists for computers churches, and writing and selling programs for other people’s computers. DATABASEYou know that a database is a collection of logically related data elements that may be structured in various ways to meet the multiple processing and retrieval needs of and individuals. There’s nothing new about databases-----early ones were chiseled in stone, penned on scrolls, and written on index cards, and computer programs are required to perform the necessary storage and retrieval operations.You’ll see in the following pages that complex data relationships and linkages may be found in all but the simplest database. The system software package that handles the different tasks associated with creating, access, and maintaining database records in called a database management system (DBMS). The programs in a DBMS package establish an in face between the database itself and the users of the database. (These users may be applications programmers, managers and others with information needs, and various OS programs)A DBMS can organize, process, and present selected data elements from the. This capability enables decision makers to search, probe, and query database contents in order to extract answers to nonrecurring and unplanned questions that aren’t available in regular reports. These questions might initially be vague and/or poorly defined, but people can“browse” the database until they have the needed information. In short, the DBMS will “manage” the stored data items and assemble the needed items from the common database in response to the queries of those who aren’t programmers. In a file-oriented system, users needing special information may communicate their needs to a programmer, who, when time permits, will write one or moreprograms to extract the data and prepare the information. The availability of a DBMS, however, offers users a much faster alternative communications path.The management information system (MIS) concept has been defined in dozens of ways. Since one organization’s model of an MIS is likely to differ from that of another, it’s not that their MIS can be defined as a net of computer-based data processing procedures developed in an organization and integrated as with manual and decision making and other necessary management functions.Although MIS models differ, most of them recognize the concepts the horizontal management structure, an organization is also divided vertically into different and functions require separate information flows. Combining the horizontal managerial levels with the vertical produces the complex, this structure is a database consisting, ideally, and externally produced data relating to past, present, and predicted future events.The task of the MIS designer is to develop the information flow needed to support making. Generally speaking, much of the information needed by managers who occupy different levels and who have different responsibilities if obtained from a collection of existing information systems (of subsystems). These systems may be tied together very closely in an MIS. More often, however, they are more loosely coupled.SQL AND SQL SERVERIBM invented a computer language back in the 1970s designed specifically for database queries called SEQUEL; those letters stand for Structured English Query language. Over time, the language has been added to so that it is not just a language for queries, but can also build databases and manage the database engine’s security. IBM released SEQUEL into the public domain, where it became known as SQL. Because of this heritage you can pronounce it“sequel”or spell it out“S-Q-L”are various versions of SQL used in today database engines. Microsoft SQL Server uses a version called Transact-SQL, or T SQL, which stands for Transaction SQL. 1.What Is SQL Server?SQL Server is a client/server relational database management system (RDBMS). That uses Transact-SQL to send requests between a client and SQL Server.2.Client/Server ArchitectureThe terms client, server, and client/server can be used to refer to very general concepts or to specific items of hardware of software. At the most general level, client is any component of a system that requests services or resources from other of a system. A server is any component of a system that provides services or resources to other components of a system.For example, when you print a document from your workstation on a network, the workstation is the client and the machine that does the print spooling is the server.Any client/server data based system consists of the following components:The server---A collection of data items and supporting objects organized and presented to facilitate services, such as searching, sorting, recombining, retrieving, updating, and analyzing data, The database consists of the physical storage of data and the database services. All data access occurs through the server; the physical data is never accessed directly by the client.The client---A software program that might be used interactively by a person or that could be an automated process. This includes all software that interacts with the server, either requesting data from of sending data to the database. Examples are management utilities (those that are part of the SQL Server product as well as those bought separately), ad hoc query and reporting software,custom applications, off-the-shelf applications, and Web server-based applications.The communication between the client and the server---The communication between the client and the server depends largely on how the client and server are implemented. Both physical and logical layers of communication can be identified.When you communicate with someone using the telephone, the telephone system is the physical layer and a spoken natural language is the logical layer of communication. For a data based the physical layer can be a net world if the server and the client are on different computers. It can be inter process communication if the server and the client are on the same computer. The logical communication structure of the physical layer may be low-level operating system calls, a proprietary data access language, or the open structured query language (SQL).SQL Server platformsThe SQL Server version server software runs only on the windows 32-bit API-based operating systems, but you can use all of the operating system platforms to create and execute client applications.SOFTWARE DESIGNSoftware design is a creative process .It requires a certain amount of flair on the part of the designer and the final design is normally from a number of preliminary designs. Design cannot be learned from a book---it must be practiced and learnt by experience and study of existing systems. Good design is the key to effective software engineering. A well-designed software system is straightforward to implement and maintain, easily understood and reliable. Badly designed system, although they may work, are likely to be expensive to maintain, difficult to test and unreliable. The design stage is therefore the most critical part of the software development process.Until fairly recently, software design was largely an ad hoc process. Given a set of requirements, usually in natural language, an informal design was prepared, often in the form of a flowchart. Coding then commenced and the design was modified as the system was implemented. When the implementation stage was complete, the design had usually changed so much from its initial specification that the original design document was a totally inadequate description of the system. This approach to software design was responsible for many dramatic and very expensive project failures. Now it is realized that completely informal notations such as flowcharts, which are close to the programming language, are inadequate vehicles for formulating and expressing system design. It is recognized that precise (although not necessarily formal) specification is an essential part of the design process and that software design is an iterative, multi-stage activity cannot be represented in any single notation. Accordingly a number of design notations such as data flow diagrams. HIPO charts, structure diagrams and design description languages have been developed which are superior to flowcharts for expressing software designs.Given a requirements definition, the software engineer must use this to derive the design of a programming satisfies these requirements. This derivation is accomplished in a number of stages:(1)The subsystems making up the programming system must be established.(2)Each subsystem must be decomposed into separate components and the subsystemspecification established by defining the operation of these components.(3)Each program may then be designed in terms of interacting subcomponents.(4)Each component must then be refined. This normally entails specifying each componentas hierarchy of subcomponents.(5)At some stage of this refinement process, the algorithms used in each component must bespecified in detail.As well as these various stages of programming system design, the software engineer may also be required to design communication mechanisms allowing processes in the system to communicate. He or she may have to design file structures, and will almost certainly have to design the data structures used in his programs. He or she will have to design test cases to validate his programs.There is no definitive way of establishing what is meant by a “good”design. Depending on the application and the particular project requirements, a good design might be a design allows very efficient code to be produced, it might be a minimal design where the implementation is as compact as possible, or it might be the most maintainable design. This latter criterion is the criterion of “goodness”adopted here. A maintainable design implies that the cost of system changes is minimized and this means that the design should be understandable and that changes should be local in effect. Both of these are achieved if the software design is highly cohesive and loosely coupled.Effective software design is best accomplished by using a consistent design methodology. There have been a vast number of design methodologies developed and used in different applications. Some of these are described by Peters (1980) and by Blank and (1983). In essence, most of these methodologies can be classified into one of three areas:(1)Top-down functional design. The system is designed from a functional viewpoint,starting with a high-level view and progressively refining this into a more detailed design.(2)Object-oriented design. The system is viewed as a collection of objects rather than asfunctions with messages passed from object to object. Each object has its own set of associated operations. Object-oriented design is based on the idea of information hiding which was first put forward by (1972) and has been described more recently by Robson (1981).(3)Data-driven design. This methodology, suggested by Jackson (1975), suggested that thestructure of a software system should reflect the structure of the data processed by that system. Therefore, the software design is derived from an analysis of the input and output system data.SOFTWARE TESTING1.Purpose of TestingNo matter how capably we write programs, it is clear from the variety of possible errors that we should check to insure that our modules are coded correctly. Many programmers view testing as a demonstration programs perform properly. However, the idea of demonstrating correctness is really the reverse of what testing is all about. We test a program in order to demonstrate the existence of an error. Because our goal is to discover errors, we can consider a test successful only when an error is discovered. Once an error is found, “debugging”or error correction is the process of determining what causes the error and of making changes to the system so that the error no longer exists.2.Stages of TestingIn the development of a large system, testing involves several stages. First, each program module is tested as a single program, usually isolated from the other programs in the system. Such testing, known as module testing or unit testing, verifies that themodule functions properly with the types of input expected from studying the module design. Unit testing is done in a controlled environment whenever possible so that the test team can feed a predetermined set of data to the module being tested and observe what output data are produced. In addition, the test team checks the internal data structures, the logic, and the boundary conditions for the input and output data.When collections of modules have been unit-tested, the next step is to insure that the interfaces among the modules are defined and handled properly. Integration testing is the process of verifying that the components of a system work together as described in the program design and system design specifications.Once we are sure that information is passed among modules according to the design prescriptions, we test the system to assure that it has the desired functionality. A function test evaluates the system to determine if the functions described by the requirements specification are actually performed by the integrated system. The result, then, is a functioning system.Recall that the requirements were specified in two ways: first in the customer’s terminology and again as a set of software and hardware requirements. The function test compares the system being built with the functions described in the software and hardware requirements. Then, a performance test compares the system with the remainder of the software and hardware requirements. If the test is performed in the customer’s actual working environment, a successful test yields a validated system. However, if the test must be performed in a simulated environment, the resulting system is a verified system.When the performance test is complete as developers are certain that the system functions according to our understanding of the system description. The next step is to confer with the customer to make certain that the system works according to the customer’s expectations. We join with the customer to perform an acceptance test in which the system is checked against the customer’s requirements description. When the acceptance test is complete he accepted system is installed in the environment in which it will be used; a final installation test is performed to make sure that the system function as it should.Although systems may differ in size, the type of testing described in each stage is necessary for assuring the proper performance of any system being developed.。

毕业设计(论文)外文资料翻译附件1：外文资料翻译译文Internet的历史起源——ARPAnetInternet是被美国政府作为一项工程进行开发的。

这项工程的目的，是为了建立远距离之间点与点的通信，以便处理国家军事范围内的紧急事件，例如核战争。

这项工程被命名为ARPAnet，它就是Internet的前身。

建立此工程的主要应用对象就是军事通讯，那些负责ARPAnet的工程师们当时也没有想到它将成为“Internet”。

根据定义，一个“Internet”应该由四或者更多的计算机连接起来的网络。

ARPAnet是通过一种叫TCP/IP的协议实现连网工作的。

此协议最基础的工作原理是：如果信息在网络中的一条路径发送失败，那么它将找到其他路径进行发送，就好象建立一种语言以便一台计算机与其他计算机“交谈”一样，但不注意它是PC，或是Macintosh。

到了20世纪80年代，ARPAnet已经开始变成目前更为有名的Internet了，它拥有200台在线主机。

国防部很满意ARPAnets的成果，于是决定全力将它培养为能够联系很多军事主机，资源共享的服务网络。

到了1984年，它就已经超过1000台主机在线了。

在1986年ARPAnet关闭了，但仅仅是建立它的机构关闭了，而网络继续存在与超过1000台的主机之间。

由于使用NSF连接失败，ARPAnet才被关闭。

NSF是将5个国家范围内的超级计算机连入ARPAnet。

随着NSF的建立，新的高速的传输介质被成功的使用，在1988年，用户能通过56k的电话线上网。

在那个时候有28，174台主机连入Internet。

到了1989年有80，000台主机连入Internet。

到1989年末，就有290，000台主机连入了。

另外还有其他网络被建立，并支持用户以惊人的数量接入。

于1992年正式建立。

现状——Internet如今，Internet已经成为人类历史上最先进技术的一种。

每个人都想“上网”去体验一下Internet中的信息财富。
