2 系统需求分析
2.1 目标
该软件需求说明书的编制是为了使用户和软件开发者双方对该软件的初始功能有一个共同的理解，使之成为整个开发工作的基础。在使用者和制作者之间达成需求共识，为下面的软件制作留下足够的功能依据，需求分析的内容包括功能、数据、性能、界面等要求。此阶段非常重要，如果在此阶段产生较大偏差，在以后的软件设计过程中则会导致崩溃性的破坏，严重的话则会导致软件工程失败，使软件重做，开发时间和费用都会以指数的形式增长。
2.2 用户的特点
用户多为一般上网用户，只需了解上网的一些基本操作。
2.3 功能需求
a）用户注册账号：用户可以在网站上填写相关资料来注册账号。
b）管理员管理：管理员输入账号密码登录后，进入相关页面对注册用户进行修改、删除等操作。
c）用户修改资料：用户输入账号密码登录后，进入相关页面对自己的资料进行修改。
d）套餐选择：用户在相关页面回答一些问题，系统根据用户的回答经过计算显示符合用户的最低套餐和其他套餐以供用户参考。
e）用户话费统计：用户进入用户话费统计页面后可以查看各话费段用户的人数或查看某年月间各话费段用户的人数。
f）套餐选择统计：用户进入套餐选择统计页面后可以查看各个套餐已选的用户人数或查看某年月间各套餐用户的人数。
2.4 性能需求
a）界面需求：本系统需具有友好的操作界面，便于用户操作。
b）稳定性：当一定范围内的用户同时访问网站时，服务端与客户端的连接速度应保持稳定，服务端性能保持稳定。
c）正确性：根据程序运作流程设计软件，每个步骤在程序中都有所体现，保证程序运行的正确性。
2.5 运行环境
系统的运行环境为：
a）硬件环境：1）CPU：Intel® Celeron® M processor-1.4GHz；2）内存：256M；3）硬盘：40GB。
b）操作系统环境：Microsoft Windows Server XP professional（简体中文版）。
c）软件工具：Microsoft Visual Studio 2005，Microsoft SQL Server 2005。
3 系统概要设计
结 论
手机套餐选用系统实现是应用Visual Studio 2005及SQL 2005作为开发平台，Windows操作系统作为运行环境的基于web浏览器的系统，通过本系统可以起到指导手机套餐选择的作用。系统建立在移动和联通现有套餐的基础上，经过分析取舍，总结了套餐共25条，尽量涵盖大部分现有套餐，满足用户需求。整个系统开发从需求分析、概要设计、详细设计、和测试都努力按照软件工程的一套来执行。需求分析阶段研究用户的具体需求。概要设计和详细设计两个阶段将需求阶段的要求，考虑总体和具体的设计办法，在编码阶段将其实现，最后通过测试来寻找程序中的错误。课题的核心集中在系统的架构和套餐选择的算法上，系统采用的是petshop4.0的设计思想，采用N层结构设计。N层结构实现了表示、数据、逻辑的分开，减少了耦合度，更加灵活，适于维护，便于系统的扩展，利于开发任务同步进行。在算法上，系统根据每个套餐设计算法，把各个套餐的花费进行了排列。用户根据结果进行选择。
本软件中仍存在不足之处，如界面不够美观，实现的功能也相对简单，安全性方面不够等等，这些缺点还有待于在以后的维护中不断地改善。

2 System Requirements Analysis
2.1 Goals
The establishment of software requirements specification is to enable users and software developers of the software, the initial function of the two sides have a common understanding, making it the basis for the entire development. In the users and producers of the consensus reached between the demand for the following functions of the software produced leave enough basis for requirements analysis includes features, data, performance, interface, and so require. At this stage is very important, if at this stage have a greater deviation in the future of software design process will result in the collapse of destruction, the worst case, would result in failure of software engineering to make the software redo, development time and cost would be exponential in the form of growth.
2.2 User Characteristics
Multi-user Internet users in general, just to understand some of the basic operation of the Internet.
2.3 Functional Requirements
a) Registered Account User: Users can fill out relevant information on the site to register the account.
b) the administrator management: an administrator enter the account password, go to the relevant pages of the registered users to modify, or delete operation.
c) users to modify the information: the user account password, go to the relevant pages for their own data to be modified.
d) package options: the user to answer some questions related to the page, the system according to the user''s answer in line with the user through the calculations show that the minimum package and other packages for the user''s reference.
e) User Huafei Statistics: User access to the user statistics page and Hua Fei Hua Fei can see the various paragraphs or view a certain number of users from various Hua Fei Duan Clear number of users.
f) Package Select Statistics: The user statistics page and enter the package option you can view the various packages have been selected the number of users or to view a Clear number of users from various packages.
2.4 Performance Requirements
a) Interface Requirements: The system must have a friendly user interface, user-friendly.
b) Stability: When at the same time within a certain range of users visit the Web site, the service client and the client connection speed should be maintained, the service-side performance remained stable.
c) correctness: In accordance with the procedure for process design software, each step in the program are reflected to ensure the correctness of program runs.
2.5 Runtime Environment
Operation of the system environment as follows:
a) Hardware Environment: 1) CPU: Intel ® Celeron ® M processor-1.4GHz; 2) Memory: 256M; 3) hard disk: 40GB.
b) operating system environment: Microsoft Windows Server XP professional (Simplified Chinese version).
c) software tools: Microsoft Visual Studio 2005, Microsoft SQL Server 2005.
3 System Design Overview
Conclusion
Cell phone use system implementation is the application package Visual Studio 2005 and SQL 2005 as a development platform, Windows operating system runtime environment as a web browser-based system, through this system can play a guiding role of mobile phone package options. System based on Mobile and Unicom''s existing packages based on the analysis of choice through, summed up the package a total of 25 as far as possible covers most of the existing packages to meet customer needs. Throughout the system development from requirements analysis, outline design, detailed design, and testing are making efforts in accordance with a set of software engineering to implement. Requirements analysis stage of the study the user''s specific needs. Summary of design and detailed design phase of the two phases will be the demand requirements, consider the general and specific design approach, in the coding phase of its implementation, the final test to find program errors. The core subjects focused on the system architecture and package selection algorithms, the system uses a petshop4.0 design ideas, using N-layer structure design. N-layer structure realized that the data and logic separation, reducing the coupling, more flexible, suitable for maintenance, easy expansion of the system, which will help development tasks simultaneously. In the algorithm, the system design algorithms based on each package, the cost of the various packages have been arranged. The user to choose based on the results.
The software, shortcomings still exist, such as the interface, not beautiful, functions are relatively simple in terms of security is not enough and so on, these shortcomings have yet to be in the future to maintain and continually improve.
