摘要

合同管理系统是典型的信息管理系统(MIS),其开发主要包括后台数据库的建立和维护以及前端应用程序的开发两个方面。对于前者要求建立起数据一致性和完整性强、数据安全性好的库。而对于后者则要求应用程序功能完备,易使用等特点。

本系统主要完成对合同信息的管理，包括添加、修改、删除，查询，打印信息以用户管理等六个方面。系统可以完成对各类信息的浏览、查询、添加、删除、修改等功能。系统的核心是添加、修改和删除三者之间的联系，每一个表的修改都将联动的影响其它的表，当完成添加或删除操作时系统会自动地完成合同信息的修改。查询功能也是系统的核心之一。此外，系统有完整的用户添加、删除和密码修改功能，并具备报表打印功能。

本论文包括需求分析、系统功能、系统设计、程序设计、系统测试及存在问题等方面，较为系统地介绍了“合同管理系统”课题开发的整个过程。

ABSTRACT

Contract Management System is a typical application of managing information system (know as MIS), which mainly includes developing the application interface of front-end and building up and maintaining the database of back-end.

Inquiring about the function of searching also is the one of the systematic nucleus. The system contains the integrity function of users increase, delete and the cipher modification, and the report form to print.

This thesis includes requirement analysis, system function, systems design, programming and the system tests and exists the aspects such as question etc, and comparatively systematically introduced the whole course of " contract management information system " subject development.
