Abstract：With the rapid development of computer technology, the traditional manual no longer meet the procurement management, more and more companies use the procurement management system software, purchasing management software is easy for companies to manage procurement operations, and save a lot of time, simplify the system processes. Paper analyzes the demand for procurement management, design goals, data structure, data flow and the main characteristics of the system, focusing on functional modules of the system detailed design and implementation methods and the development of the key technologies used in the system. The system is divided into three main modules, employee rights management module,basic data management module, procurement management module. The system can be fast and convenient management of procurement operations and to keep abreast of the procurement of goods and use the inventory to enable the company to make decisions quickly, adjust the procurement operations. The system can also save a lot of manual data, long life, low cost, large memory capacity, improve the efficiency of procurement operations of the company, the development of the company is very helpful. System uses the more popular web application technology --- JSP, Java, Ajax, the use of B/S model makes the system more convenient, using MY SQL as the backend database, using JDBC technology for the interconnection with the background database, using JavaBean technology encapsulates the common operations on the database. At the same time, the system uses the more popular web design patterns MVC model allows expansion of the system greatly enhanced.
