随着信息技术的发展及ERP系统的益普及，计算机在企业管理中的作用越来越不容忽视。企业之间通过网络交易的趋势越来越明显。在这种环境中，采购作为企业生产经营的一个重要环节应加强管理，充分利用外部环境条件，逐步实现企业物资采购的网络化管理。企业物资采购网络管理系统是针对企业内部而设计的，应用于企业的局域网，这样可以使得企业内部管理更有效的联系起来。
本课题就是针对企业的采购管理，开发一个基于C/S（Client/Server）构架的管理系统，我采用了目前流行的Powerbuilder做开发工具，后台采用SQL Server数据库。其中系统涉及系统管理、基础数据、单据录入三大模块。系统管理模块包括：用户管理、志管理、修改密码、注销、退出系统。基础数据模块包括：产品编码、供应商信息、员工信息、仓库信息、商品信息。单据录入模块包括：订单管理、外销清单、内销清单、入库单、出库单。论文首先全面而系统地研究了构建一个企业物资采购网络管理系统所必备的各种知识和技术手段，进行系统可行性分析，介绍系统开发环境，设计系统数据库，规划企业物资采购流程，接下来进行系统总体设计，子系统的开发与实现，最后是测试、安装与发布的说明。
论文在撰写过程中，力求将理论与实践结合起来，在对企业物资采购理论进行阐述的同时，配合模拟系统从实际应用和作技巧上加以说明，以达到对企业物资采购管理系统更深层次的理解和认识。

With the development of the information technology and the prevalence of the ERP system, it is hardly to ignore the play of the computer in enterprise management. It is more apparent that many commercial actions among many enterprises are taking place in the network. Under the circumstances, purchasing management, which is an important link of enterprise operation, must be strengthened firstly. Then, purchasing management will be put into execution with the good condition, which the outer circumstances provide. Aiming at the management in enterprise, the system, which will be put into execution with LAN, will make the management in enterprise better.
The thesis aims at the purchasing management in enterprise, which is based on C/S(Client/Server) structure. I choose the prevalent PowerBuilder as development tool, and SQL Server as background database. The system includes three modules: system management, basal data, enter bill of document. system management module includes: users management, log file management, amending password, logout, exit. basal data module includes: production coding, supplier information, employee information, storage information, commodity information. enter bill of document module includes: order form management, export bill, sale in domestic market, bill of enter and out of storage. Starting with conceiving an application system of purchasing management in enterprise, we need to investigate the knowledge and the technique, then analyse the feasibility of the system, introduce the develop environment, design database and the flow of the purchasing management. The following is that whole-design, developing subsystem, the instruction of testing, installation and issuance.
During the course of writing this article, the author strives to integrate theory and practice. While expatiating the theory of purchasing management in enterprise, the author illuminates the application and operation skill combining the system so as to make a better understanding to purchasing management in enterprise.
