【摘要】 本论文就基于网络环境下的信息系统的实现进行了研究。讨论了基于网络环境下的信息系统总体设计，数据库的优化设计，数据库的完整性设计，系统安全策略设计，后期打印报表设计，有效的软件测试方法以及对历史数据的处理等方面的问题。在此基础上完成了新疆师范大学校园网应用软件系统中学生管理子系统和科研管理子系统的设计和实现工作。目前，此系统正在运行中，该系统的应用，大大提高了该校的管理水平和工作效率。 本课题采用了新型的系统结构，使得系统资源利用率高，响应速度快，充分体现了服务器的大容量存储能力及强大的计算能力和容错能力，减少了网络中的数据流量，提高了程序执行效率。整个数据库系统采用主动性的触发机制，以保证数据库的完整性及安全性约束机制。采用多级保密体系，可靠保证数据的安全。并针对学生这样一个人员流动量较大的系统，提出了合理的历史数据处理的方法和一套用于系统测试的自动生成数据的方法。并针对系统中报表繁多，格式各异的特点，建立了一种报表生成和打印的新思路。 本系统的设计和实现是面向对象技术和网络数据库开发相结合的一次新的探索，其方法对于其它企事业单位网络信息系统的开发具有较好的研究和参考价值。更多还原

【Abstract】 As a mature technology, database is applied in all ways. Internet changed our life greatly, Intranet in internal network of enterprises is popularizing.I have assumed the task to build a database system for managing the information of Students Management Project and Scientific Research Project for Xin Jiang University base on network. After the stage of requirement analysis, we studied the method of system designing and the model of the system. We also studied the designing and realizing of the database, and how to guarantee the data integrality, how to guarantee the system security. I take part in the requirement analysis, preliminary design detailed design, coding and testing.We use the SQL Server relational database management system based on Client/Server computer model as the server database and Visual Basic as the client-developing tool. During the process of designing, object-oriented programming is used. As we use many tools such as Visio, ER-win, Excel, Source-safe to designing this fine expandability and small redundancy database, so the reliability and efficiency are increased. We have changed the fix data report model and designed a flexible data report. Considering that the student system has large amount of history data, I provide a method to deal with the history data, this make it easy to maintain the database system and shorten the time for querying and statistics.The method of this system designing and realizing can be applied in other managing system.更多还原
