摘要

伴随着现代化高节奏管理体系的发展，人与人，企业与企业，甚至国家与国家之间的往来越来越紧密，信誉成为其中至关重要的因素（有关资料显示：67%的刑事案件是直接或间接由于合同的管理不当引起的）。企业现有管理手段和管理模式存在着许多弊端和不足，合同管理是企业管理中的一个不可缺少的重要组成部分。由于合同形式的多样性和履行过程的多变性，许多企业对此很少有一个较好的办法来及时有效地实施合同的起草，修改，统计，监控等一系列管理工作。这就直接限制了企业之间的交流合作。随着问题的进一步激化,寻求一种高效的合同管理方式已迫在眉睫。因此，开发一套功能完善的合同管理系统，成为解决这一问题的最有效途径之一。

本文系统阐述了合同管理系统设计与实现的基本思路，并对各功能模块做了详细的分析与设计。

本系统采用了结构化分析与设计方法，应用Microsoft Visual C编写，后台使用SQL Server 2000数据库，系统可靠性较高，且易于维护。在实际使用过程中能够很好的完成预期的功能，体现出管理信息系统的实际作用，为实现商务系统中涉及的合同管理信息化打下了坚实的基础。

Abstract

The modern high rhythm that accompany with the development manages the system, the person has something to do with person, business enterprise and business enterprise, even nationally and the come-and-go of the national more and more closely, prestige becoming among them to important factor in pass( data manifestation:47% criminal case is direct or indirectly because the management of the contract is not appropriate cause of).Current management in business enterprise means with manage the mode exist many irregularities with shortage, the contract management is an indispensable importance within business enterprise management to constitute the part .Because variety of the contract form with implement the process changes sex more, many business enterprises few to this a good way to on time puts availably into practice the contract drafts, modifying, supervising and control etc. a series management work .This limited the exchanges cooperation of the business enterprise

directly .Further arouse to turn along with the problem, look for a kind of efficiently of the contract manages the way already of the utmost urgency . Therefore, develop the perfect contract in a set of functions management system, become to resolve the one of the most valid paths in this problem.

The paper presents the contract management system design and implementation of the basic ideas, as well as the functional modules do a detailed analysis and design.

The system uses a structured analysis and design methods, applications in Microsoft Visual C, background using SQL Server 2000 database, the higher system reliability and easy maintenance. In actual use of the process to be completed well in the expected function, reflect management information system the actual effect To achieve business system for the management of information technology contracts to lay a solid foundation.
