任务书基于android studio的图书管理系统的APP开发

毕业设计论文任务书一、题目及专题:2、专题无二、课题来源及选题依据图书作为一种信息资源,用户阅读的资料繁多,包含很多的信息数据的管理。
以前,有很多的图书管理都是手工的,尚未使用计算机进行管理。
根据调查得知,人们对图书管理的方式主要是计算机管理,及少量的基于文本、表格等纸质媒介的手工处理。
手工处理对于大量的图书信息管理很不方便,耗时耗力,而且容易出错。
对于大中型的图书馆来说,计算机管理已经成为家常便饭,好的计算机图书管理系统可以相当容易的实现对图书、用户的管理,安全性和稳定性较高,已经成为这些图书管理主流管理方式[3]。
但是,这只是对于图书管理人员来说的。
对那些我那个图书馆来回跑的用户来说,这样的情况还是很不方便的。
在移动互联发展极速的今天,作为主流管理的计算机已经不能满足一些人们的要求,所以,作为移动互联时代标志性的客户端工具——智能手机的出现就显得有些理所当然了[4]。
而基于android 平台的智能手机就是其中的代表。
智能手机就像一台微型电脑,具有强大的计算和存储能力,可以通过通信网络来实现网络的介入,可以随时随地的使用。
这样的功能弥补了计算机携带不方便的不足。
所以,基于android 平台的图书管理系统客户端,也就满足了用户与图书馆交互的不足[5]。
通过android 平台的图书管理系统客户端,用户可以很好地为用户提供方便,随时随地了解图书信息及图书借阅。
而智能手机的普及可以使得这个图书管理系统得到广泛的使用[6]。
三、本设计(论文或其他)应达到的要求:语言的特点及使用范围,并且掌握面向对象的程序设计方法。
2、了解数据库原理,并且能够独立运用SQL语言,以及JAVA知识。
3、了解数据库数据类型:包括整数类型、浮点数类型、字符串类型、日期类型、以及其他类型。
4、掌握每个模块的实现功能并且将它通过视图画出。
5、掌握整个系统的代码设计思路,并且了解其中架构过程。
6、独立完成代码对各个模块的功能实现。

容和可以进行的操作和从热搜图书进入的图书详情页是一样的。
1.3 架构设计
项目整体的架构以后端为主,前端的设计比较简单,所以这里只列出并且介绍后端的部分,整体架构如图2所示。
1.3.1 Android客户端
这一层表示用户直接操作的部分,是服务器和用户沟通的窗口。
1.3.2 反向代理层
这一层使用Nginx服务器来进行反向代理,Nginx接收客户端发来的请求,并进行请求的分发,将静态资源的请求分发给CDN,将其他请求分发给uWSGI服务器实例。
1.3.3 服务器实例层
uWSGI是真正进行数据处理和响应的服务器实例,由若干实例组成,分别完成不同模块的请求任务,以此来动态调配资源和提高响应速度,增强容灾能力。
1.3.4 核心服务层
底层的是P y t h o n运行支持环境,为所有的后端模块提供环境支持。
在Python运行支持环境之上是Django框架层,在这一层中,使用Django框架实现了用户管理模块、企业管理模块、身份验证模块、扩展模块以及日志模块。
这几个模块分别运行在不同的u W S G I服务器实例中,以实现功能和维护的解耦。
这些不同的后端模块进行通信使用的是RPC(远程过程调用)/MessageQueue(消息队列)/ RESTful API的方法。

(完整版)基于Android开发的外文文献

(完整版)基于Android开发的外文文献AndroidAndroid, as a system, is a Java-based operating system that runs on the Linux 2.6 kernel. The system is very lightweight and full featured. Android applications are developed using Java and can be ported rather easily to the new platform. If you have not yet downloaded Java or are unsure about which version you need, I detail the installation of the development environment in Chapter 2. Other features of Android include an accelerated 3-D graphics engine (based on hardware support), database support powered by SQLite, and an integrated web browser.If you are familiar with Java programming or are an OOP developer of any sort, you are likely used to programmatic user interface (UI) development—that is, UI placement which is handled directly within the program code. Android, while recognizing and allowing for programmatic UI development, also supports the newer, XML-based UI layout. XML UI layout is a fairly new concept to the average desktop developer. I will cover both the XML UI layout and the programmatic UI development in the supporting chapters of this book.One of the more exciting and compelling features of Android is that, because of its architecture, third-party applications—including those that are “home grown”—are executed with the same system priority as those that are bundled with the core system. This is a major departure from most systems, which give embedded system apps a greater execution priority than the thread priority available to apps created by third-party developers. Also, each application is executed within its own thread using a very lightweight virtual machine.Aside from the very generous SDK and the well-formed libraries that are available to us to develop with, the most exciting feature for Android developers is that we now have access to anything the operating system has access to. In other words, if you want to create an application that dials the phone, you have access to the phone’s dialer; if you want to create an application that utilizes the phone’s internal GPS (if equipped), you have access to it. The potential for developers to create dynamic and intriguing applications is now wide open.On top of all the features that are available from the Android side of the equation, Google has thrown in some very tantalizing features of its own. Developers of Android applications will be able to tie their applications into existing Google offerings such as Google Maps and the omnipresent Google Search. Suppose you want to write an application that pulls up a Google map of where an incoming call is emanating from, or you want to be able to store common search results with your contacts; the doors of possibility have been flung wide open with Android.Chapter 2 begins your journey to Android development. You will learn the how’s and why’s of using specific development environments or integrated development environments (IDE), and you will download and install the Java IDE Eclipse.Application ComponentsA central feature of Android is that one application can make use of elements of other applications (provided those applications permit it). For example, if your application needs to display a scrolling list of images and another application has developed a suitable scroller and made it available to others, you can call upon that scroller to do the work, rather than develop your own. Your application doesn't incorporate the code of theother application or link to it. Rather, it simply starts up that piece of the other application when the need arises.For this to work, the system must be able to start an application process when any part of it is needed, and instantiate the Java objects for that part. Therefore, unlike applications on most other systems, Android applications don't have a single entry point for everything in the application (no main() function, for example). Rather, they have essential components that the system can instantiate and run as needed. There are four types of components:ActivitiesAn activity presents a visual user interface for one focused endeavor the user can undertake. For example, an activity might present a list of menu items users can choose from or it might display photographs along with their captions. A text messaging application might have one activity that shows a list of contacts to send messages to, a second activity to write the message to the chosen contact, and otheractivities to review old messages or change settings. Though they work together to form a cohesive user interface, each activity is independent of the others. Each one is implemented as a subclass of the Activity base class.An application might consist of just one activity or, like the text messaging application just mentioned, it may contain several. What the activities are, and how many there are depends, of course, on the application and its design. Typically, one of the activities is marked as the first one that should be presented to the user when the application is launched. Moving from one activity to another is accomplished by having the current activity start the next one.Each activity is given a default window to draw in. Typically, the window fills the screen, but it might be smaller than the screen and float on top of other windows. An activity can also make use of additional windows — for example, a pop-up dialog that calls for a user response in the midst of the activity, or a window that presents users with vital information when they select a particular item on-screen.The visual content of the window is provided by a hierarchy of views — objects derived from the base View class. Each view controls a particular rectangular space within the window. Parent views contain and organize the layout of their children. Leaf views (those at the bottom of the hierarchy) draw in the rectangles they control and respond to user actions directed at that space. Thus, views are where the activity's interaction with the user takes place.For example, a view might display a small image and initiate an action when the user taps that image. Android has a number of ready-made views that you can use — including buttons, text fields, scroll bars, menu items, check boxes, and more.A view hierarchy is placed within an activity's window by the Activity.setContentView() method. The content view is the View object at the root of the hierarchy. (See the separate User Interface document for more information on views and the hierarchy.)ServicesA service doesn't have a visual user interface, but rather runs in the background for an indefinite period of time. For example, a service might play background musicas the user attends to other matters, or it might fetch data over the network or calculate something and provide the result to activities that need it. Each service extends the Service baseclass.A prime example is a media player playing songs from a play list. The player application would probably have one or more activities that allow the user to choose songs and start playing them. However, the music playback itself would not be handled by an activity because users will expect the music to keep playing even after they leave the player and begin something different. To keep the music going, the media player activity could start a service to run in the background. The system would then keep the music playback service running even after the activity that started it leaves the screen.It's possible to connect to (bind to) an ongoing service (and start the service if it's not already running). While connected, you can communicate with the service through an interface that the service exposes. For the music service, this interface might allow users to pause, rewind, stop, and restart the playback.Like activities and the other components, services run in the main thread of the application process. So that they won't block other components or the user interface, they often spawn another thread for time-consuming tasks (like music playback). See Processes and Threads, later.Broadcast receiversA broadcast receiver is a component that does nothing but receive and react to broadcast announcements. Many broadcasts originate in system code — for example, announcements that the timezone has changed, that the battery is low, that a picture has been taken, or that the user changed a language preference. Applications can also initiate broadcasts —for example, to let other applications know that some data has been downloaded to the device and is available for them to use.An application can have any number of broadcast receivers to respond to any announcements it considers important. All receivers extend the BroadcastReceiver base class.Broadcast receivers do not display a user interface. However, they may start anactivity in response to the information they receive, or they may use the NotificationManager to alert the user. Notifications can get the user's attention in various ways —flashing the backlight, vibrating the device, playing a sound, and so on. They typically place a persistent icon in the status bar, which users can open to get the message.Content providersA content provider makes a specific set of the application's data available to other applications. The data can be stored in the file system, in an SQLite database, or in any other manner that makes sense. The content provider extends the ContentProvider base class to implement a standard set of methods that enable other applications to retrieve and store data of the type it controls. However, applications do not call these methods directly. Rather they use a ContentResolver object and call its methods instead. A ContentResolver can talk to any content provider; it cooperates with the provider to manage any interprocess communication that's involved.See the separate Content Providers document for more information on using content providers.Whenever there's a request that should be handled by a particular component, Android makes sure that the application process of the component is running, starting it if necessary, and that an appropriate instance of the component is available, creating the instance if necessary.Key Skills & Concepts●Creating new Android projects●Working with Views●Using a TextView●Modifying the main.xml fileCreating Your First Android Project in EclipseTo start your first Android project, open Eclipse. When you open Eclipse for the first time, it opens to an empty development environment (see Figure 5-1), which is where you want to begin. Your first task is to set up and name the workspace for your application. Choose File | New | Android Project, which will launch the New AndroidProject wizard.CAUTION Do not select Java Project from the New menu. While Android applications are written in Java, and you are doing all of your development in Java projects, this option will create a standard Java application. Selecting Android Project enables you to create Android-specific applications.If you do not see the option for Android Project, this indicates that the Android plugin for Eclipse was not fully or correctly installed. Review the procedure in Chapter 3 for installing the Android plugin for Eclipse to correct this.The New Android Project wizard creates two things for youA shell application that ties into the Android SDK, using the android.jar file, and ties the project into the Android Emulator. This allows you to code using all of the Android libraries and packages, and also lets you debug your applications in the proper environment.Your first shell files for the new project. These shell files contain some of the vital application blocks upon which you willbe building your programs. In much the same way as creating a Microsoft .NET application in Visual Studio generates some Windows-created program code in your files, using the Android Project wizard in Eclipse generates your initial program files and some Android-created code. In addition, the New Android Project wizard contains a few options, shown next, that you must set to initiate your Android project. For the Project Name field, for purposes of this example, use the title HelloWorldT ext. This name sufficiently distinguishes this Hello World! project from the others that you will be creating in this chapter.In the Contents area, keep the default selections: the Create New Project in Workspace radio button should be selected and the Use Default Location check box should be checked. This will allow Eclipse to create your project in your default workspace directory. The advantage of keeping the default options is that your projects are kept in a central location, which makes ordering, managing, and finding these projects quite easy. For example, if you are working in a Unix-based environment, this path points to your $HOME directory.If you are working in a Microsoft Windows environment, the workspace pathwill be C:/Users//workspace, as shown in the previous illustration. However, for any number of reasons, you may want to uncheck the Use Default Location check box and select a different location for your project. One reason you may want to specify a different location here is simply if you want to choose a location for this specific project that is separate from other Android projects. For example, you may want to keep the projects that you create in this book in a different location from projects that you create in the future on your own. If so, simply overridethe Location option to specify your own custom location directory for this project.。

毕业设计说明书英文文献及中文翻译班姓 名:学 院:专指导教师:2014 年 6 月软件学院 软件工程An Introduction to JavaThe first release of Java in 1996 generated an incredible amount of excitement, not just in the computer press, but in mainstream media such as The New York Times, The Washington Post, and Business Week. Java has the distinction of being the first and only programming language that had a ten-minute story on National Public Radio. A $100,000,000 venture capital fund was set up solely for products produced by use of a specific computer language. It is rather amusing to revisit those heady times, and we give you a brief history of Java in this chapter.In the first edition of this book, we had this to write about Java: “As a computer language, Java’s hype is overdone: Java is certainly a good program-ming language. There is no doubt that it is one of the better languages available to serious programmers. We think it could potentially have been a great programming language, but it is probably too late for that. Once a language is out in the field, the ugly reality of compatibility with existing code sets in.”Our editor got a lot of flack for this paragraph from someone very high up at Sun Micro- systems who shall remain unnamed. But, in hindsight, our prognosis seems accurate. Java has a lot of nice language features—we examine them in detail later in this chapter. It has its share of warts, and newer additions to the language are not as elegant as the original ones because of the ugly reality of compatibility.But, as we already said in the first edition, Java was never just a language. There are lots of programming languages out there, and few of them make much of a splash. Java is a whole platform, with a huge library, containing lots of reusable code, and an execution environment that provides services such as security, portability across operating sys-tems, and automatic garbage collection.As a programmer, you will want a language with a pleasant syntax and comprehensible semantics (i.e., not C++). Java fits the bill, as do dozens of other fine languages. Some languages give you portability, garbage collection, and the like, but they don’t have much of a library, forcing you to roll your own if you want fancy graphics or network- ing or database access. Well, Java has everything—a good language, a high-quality exe- cution environment, and a vast library. That combination is what makes Java an irresistible proposition to so many programmers.SimpleWe wanted to build a system that could be programmed easily without a lot of eso- teric training and which leveraged t oday’s standard practice. So even though wefound that C++ was unsuitable, we designed Java as closely to C++ as possible in order to make the system more comprehensible. Java omits many rarely used, poorly understood, confusing features of C++ that, in our experience, bring more grief than benefit.The syntax for Java is, indeed, a cleaned-up version of the syntax for C++. There is no need for header files, pointer arithmetic (or even a pointer syntax), structures, unions, operator overloading, virtual base classes, and so on. (See the C++ notes interspersed throughout the text for more on the differences between Java and C++.) The designers did not, however, attempt to fix all of the clumsy features of C++. For example, the syn- tax of the switch statement is unchanged in Java. If you know C++, you will find the tran- sition to the Java syntax easy. If you are used to a visual programming environment (such as Visual Basic), you will not find Java simple. There is much strange syntax (though it does not take long to get the hang of it). More important, you must do a lot more programming in Java. The beauty of Visual Basic is that its visual design environment almost automatically pro- vides a lot of the infrastructure for an application. The equivalent functionality must be programmed manually, usually with a fair bit of code, in Java. There are, however, third-party development environments that provide “drag-and-drop”-style program development.Another aspect of being simple is being small. One of the goals of Java is to enable the construction of software that can run stand-alone in small machines. The size of the basic interpreter and class support is about 40K bytes; adding the basic stan- dard libraries and thread support (essentially a self-contained microkernel) adds an additional 175K.This was a great achievement at the time. Of course, the library has since grown to huge proportions. There is now a separate Java Micro Edition with a smaller library, suitable for embedded devices.Object OrientedSimply stated, object-oriented design is a technique for programming that focuses on the data (= objects) and on the interfaces to that object. To make an analogy with carpentry, an “object-oriented” carpenter would be mostly concerned with the chair he was building, and secondari ly with the tools used to make it; a “non-object- oriented” carpenter would think primarily of his tools. The object-oriented facilities of Java are essentially those of C++.Object orientation has proven its worth in the last 30 years, and it is inconceivable that a modern programming language would not use it. Indeed, the object-oriented features of Java are comparable to those of C++. The major difference between Java and C++ lies in multiple inheritance, which Java has replaced with the simpler concept of interfaces, and in the Java metaclass model (which we discuss in Chapter 5). NOTE: If you have no experience with object-oriented programming languages, you will want to carefully read Chapters 4 through 6. These chapters explain what object-oriented programming is and why it is more useful for programming sophisticated projects than are traditional, procedure-oriented languages like C or Basic.Network-SavvyJava has an extensive library of routines for coping with TCP/IP protocols like HTTP and FTP. Java applications can open and access objects across the Net via URLs with the same ease as when accessing a local file system.We have found the networking capabilities of Java to be both strong and easy to use. Anyone who has tried to do Internet programming using another language will revel in how simple Java makes onerous tasks like opening a socket connection. (We cover net- working in V olume II of this book.) The remote method invocation mechanism enables communication between distributed objects (also covered in V olume II).RobustJava is intended for writing programs that must be reliable in a variety of ways.Java puts a lot of emphasis on early checking for possible problems, later dynamic (runtime) checking, and eliminating situations that are error-prone. The single biggest difference between Java and C/C++ is that Java has a pointer model that eliminates the possibility of overwriting memory and corrupting data.This feature is also very useful. The Java compiler detects many problems that, in other languages, would show up only at runtime. As for the second point, anyone who has spent hours chasing memory corruption caused by a pointer bug will be very happy with this feature of Java.If you are coming from a language like Visual Basic that doesn’t explicitly use pointers, you are probably wondering why this is so important. C programmers are not so lucky. They need pointers to access strings, arrays, objects, and even files. In Visual Basic, you do not use pointers for any of these entities, nor do you need to worry about memory allocation for them. On the other hand, many data structures are difficult to implementin a pointerless language. Java gives you the best of both worlds. You do not need point- ers for everyday constructs like strings and arrays. You have the power of pointers if you need it, for example, for linked lists. And you always have complete safety, because you can never access a bad pointer, make memory allocation errors, or have to protect against memory leaking away.Architecture NeutralThe compiler generates an architecture-neutral object file format—the compiled code is executable on many processors, given the presence of the Java runtime sys- tem. The Java compiler does this by generating bytecode instructions which have nothing to do with a particular computer architecture. Rather, they are designed to be both easy to interpret on any machine and easily translated into native machine code on the fly.This is not a new idea. More than 30 years ago, both Niklaus Wirth’s original implemen- tation of Pascal and the UCSD Pascal system used the same technique.Of course, interpreting bytecodes is necessarily slower than running machine instruc- tions at full speed, so it isn’t clear that this is even a good idea. However, virtual machines have the option of translating the most frequently executed bytecode sequences into machine code, a process called just-in-time compilation. This strategy has proven so effective that even Microsoft’s .NET platform relies on a virt ual machine.The virtual machine has other advantages. It increases security because the virtual machine can check the behavior of instruction sequences. Some programs even produce bytecodes on the fly, dynamically enhancing the capabilities of a running program.PortableUnlike C and C++, there are no “implementation-dependent” aspects of the specifi- cation. The sizes of the primitive data types are specified, as is the behavior of arith- metic on them.For example, an int in Java is always a 32-bit integer. In C/C++, int can mean a 16-bit integer, a 32-bit integer, or any other size that the compiler vendor likes. The only restriction is that the int type must have at least as many bytes as a short int and cannot have more bytes than a long int. Having a fixed size for number types eliminates a major porting headache. Binary data is stored and transmitted in a fixed format, eliminating confusion about byte ordering. Strings are saved in a standard Unicode format. The libraries that are a part of the system define portable interfaces. For example,there is an abstract Window class and implementations of it for UNIX, Windows, and the Macintosh.As anyone who has ever tried knows, it is an effort of heroic proportions to write a pro- gram that looks good on Windows, the Macintosh, and ten flavors of UNIX. Java 1.0 made the heroic effort, delivering a simple toolkit that mapped common user interface elements to a number of platforms. Unfortunately, the result was a library that, with a lot of work, could give barely acceptable results on different systems. (And there were often different bugs on the different platform graphics implementations.) But it was a start. There are many applications in which portability is more important than user interface slickness, and these applications did benefit from early versions of Java. By now, the user interface toolkit has been completely rewritten so that it no longer relies on the host user interface. The result is far more consistent and, we think, more attrac- tive than in earlier versions of Java.InterpretedThe Java interpreter can execute Java bytecodes directly on any machine to which the interpreter has been ported. Since linking is a more incremental and lightweight process, the development process can be much more rapid and exploratory.Incremental linking has advantages, but its benefit for the development process is clearly overstated. Early Java development tools were, in fact, quite slow. Today, the bytecodes are translated into machine code by the just-in-time compiler.MultithreadedThe benefits of multithreading are better interactive responsiveness and real-time behavior.If you have ever tried to do multithreading in another language, you will be pleasantly surprised at how easy it is in Java. Threads in Java also can take advantage of multi- processor systems if the base operating system does so. On the downside, thread imple- mentations on the major platforms differ widely, and Java makes no effort to be platform independent in this regard. Only the code for calling multithreading remains the same across machines; Java offloads the implementation of multithreading to the underlying operating system or a thread library. Nonetheless, the ease of multithread- ing is one of the main reasons why Java is such an appealing language for server-side development.Java程序设计概述1996年Java第一次发布就引起了人们的极大兴趣。

所谓移动互联网是将移动通信和互联网整合在一起,移动设备(包括手机和上网本)可以随时随地地访问互联网资源和应用。
智能手机是移动互联网时代一个标志性的客户端工具,它和传统的手机是有区别的,它就像一台“小电脑”,具有独立的操作系统,可以自由安装、卸载软件,具有强大的计算和存储能力,可以通过移动通信网络来实现无线网络接入。
对于移动终端设备飞速发展的今天,传统WEB上的应用出现在手机终端是一个大的趋势。
而基于Android开发的图书馆管理系统手机客户端,正是对这一趋势的良好体现,Android 平台下的图书馆管理系统的开发,能很好的为用户提供方便,用户能通过它能随时随地的了解系统的实时信息,做到信息的实时化。
通过Android平台下的图书馆管理系统客户端的开发,与传统WEB应用进行良好的互补。
同时,对于校内的图书馆管理系统来说,手机对于学生是必不可少的一个物品,手机客户端这种形式的图书馆管理系统,能更加贴近学生的生活习惯,并且适合学生年龄段的习性,这对学生更多的接触到图书馆的信息有一定得促进作用。
1.2课题的现状目前国内的基于Android平台的图书馆管理系统客户端还不成熟,大多数的图书馆管理系统都出现在传统的WEB应用上,在这个环境下,基于Android平台的图书馆管理系统客户端属于一个崭新的应用。
作为一个不太成熟的应用,大多数图书馆管理系统都是出现在学习android开发的一个项目中,作为学习中的一个练习项目。
目前,绝大部分的网络应用都还是传统的WEB应用,但面对Android手机如此迅速发展的今天,传统WEB的应用不能满足人们随时随地体验网络应用的想法,所以,出现在手机终端的应用将会越来越多,同时其发展的速度也会越来越快。
校内图书馆管理系统作为传统WEB应用,也必将在手机客户端上得到应用。
1.3课题的内容由此出现大量的应用出现在手机上,基于Android平台的图书馆管理系统手机客户端是依据现在的形式所开发的,它是一套基于开放性的图书馆管理系统,它有传统WEB上图书馆管理系统的大部分功能。
整个系统分为前台界面管理和后台服务器管理两部分,划分为用户管理、图书管理、信息管理等三个部分。
在前台管理中,用户进行注册、登录、查询特定图书等功能;后台管理模块,负责控制前台界面管理的所有功能;本系统设置了学生用户和管理员两类,两类用户都是使用同一个平台,只是权限不同。
学生用户只能注册、查询图书等功能;管理员拥有最高权限,可以对已经毕业的学生用户账号进行删除,查询学生用户信息,实时更新图书馆的新书,发布图书馆最新信息等权限。
本图书馆管理系统,能够适用于各类图书馆,具有良好的可操作性,可以随时的查询你所需要的图书信息,只要你的智能手机安装了本系统客户端,系统大大的方便了学生的图书查询的。
本系统采用C/S结构,后台服务器使用Servlet编写服务器,同时用Tomcat发布服务,前台客户端环境使用的是ANDROID控件。
通过JDBC来调用Oracle数据库,来实现手机客户端与服务器之间数据传输。
第2章软件设计及开发工具介绍为了使软件开发能够顺利进行,使开发人员对系统各个模块的性能、系统接口、系统开发及运行环境和计算机内部处理的逻辑及物理流程有更清晰的认识,更利于源程序的开发,现对系统的总体设计和系统结构设计及开发工具和关键技术做详细说明。
2.1总体设计基于ANDROID平台开发的图书馆管理系统客户端从设计者的角度来看,用户角色分为学生用户和管理员两类;功能包括注册、登录、密码找回、书籍查询、图书实时更新、普通用户管理共六大部分。
其中系统管理中的学生用户权限包括注册、登录、密码找回、书籍查询等四个模块;管理员的权限则是除了学生用户具有的权限外还有实时更新图书信息、学生用户管理等模块。
从使用者的角度来看分为前台和后台管理两大部分。
后台管理模块是本系统的关键部分之一,它是系统维护和信息管理平台。
根据现实需要,本系统后台管理用户有两类:管理员和学生用户。
这两类用户使用的系统管理平台都是同一个平台上,只不过他们执行的权限不同。
2.2系统结构本系统总体逻辑结构为C/S结构,结构图如图2-1所示:图2.1C/S结构图2.3开发工具介绍和关键技术2.3.1Eclipse的介绍Eclipse 是一个开放源代码的、基于Java 的可扩展开发平台。
就其本身而言,它只是一个框架和一组服务,用于通过插件组件构建开发环境。
幸运的是,Eclipse 附带了一个标准的插件集,包括Java 开发工具(Java Development Kit,JDK)。
