数据库的建立和系统模块功能的实现

【摘 要】随着现代计算机科学的发展，计算机信息系统越来越受到重视，网络已经成为人们交流信息的重要方式，所以基于网络平台的各种系统不断出现，网上论坛已经成为人们交流的一种重要工具。本文首先介绍开发工具JSP，接着介绍了JSP的数据访问技术，最后详细讲解了用JSP开发的论坛，这一部分主要包括数据库的建立和系统模块功能的实现，最后说明了系统存在问题和前景展望。

开发本软件的基本步骤：系统需求分析、系统设计和数据库设计、详细设计、系统实现和维护。在系统需求分析中先后使用了系统的功能结构图、ER图分析了系统所需的各种数据。在系统的设计过程中，采用了模块独立法，比较详细的展现了各个模块的功能。在数据库和关系表的设计当中，力求层次清晰与明确，设计合理并简单实用。在系统具体实行阶段中，精心细致的画出了各个窗体并给出了相应的事件和代码，以实现各个窗体的作用。

最后，文章首先对网上论坛进行了概述，并对网上论坛原理做了综合介绍。应用JSP语言和Microsoft Access数据库实现了网上论坛系统。经过本机进行的模拟测试，该系统在一定程度上增加了网上论坛的功能性和实用性。

ABSTRACT

【Abstract】’s developing, computer has became a kind of important tools which one for peoples exchanging each other’s information The network also has taken an impotent role in our daily life. The first part in the comprehension it will introducing the tool of JSP, and then introducing the JSP data access technologies, finally will explaining the development about the online shop system’s using of JSP. In this part it will include database creation and the system function’s realization. Finally to tell the matter and shortage of the system, in order to get well use in the future.

The basic steps of software developing as these: requirements analysis, concept design, system logic and physical design, system implementation and maintenance. The system used the data dictionary, data flow, system function block diagram. ER diagram of the system analysis the variety of data. In the system design process by using a module independent method, showing in more detail the function of each module. Table in the library and designs, and strive to level of clarity, the design is simple and practical. Specific implementation phase carefully detailed drawing of each form and the corresponding event and code to achieve the role of each form in the system. Although the system design is simple, but there are certain practical.

Finally, the filtration system was fulfilled with JSP language and Microsoft Access database. After simulation tests on our computer was made, we had a re
