摘要

Trade enterprises because of the length of the shorter supply chain business, relatively low, without considering the policy tilt and quasi monopoly, has always belonged to the complex external environment, full and intense market competition in high risk industries. In the background of global economic liberalization and internationalization, the enterprises in order to meet the environmental requirements, the need for effective integration and fast on various aspects of the enterprise resources, in order to achieve the expansion of the overall business performance, cost reduction target. How to achieve the above management requirements is a long-standing problem of trading enterprises. The special requirements of specific conditions and related enterprises based on the trade industry, the paper studies the present situation of the basic principle of ERP, the development and application of ERP technology at home and abroad, combined with the characteristics and the existing problems in the informatization process of trade enterprises, pointed out that trade enterprise application ERP Technology is necessary and feasible, and from the theoretical analysis and system realization of two aspects the following work: first, through a comprehensive literature analysis, the basic principle and development of ERP technology and application status of domestic and foreign research of ERP, combined with the characteristics and the existing problems in the informatization process of trade enterprises, puts forward the overall framework, in line with the requirements of industry trade ERP system function module and the module of data integration model, and the module is analyzed and designed, and detailed program development. Secondly, through the research of the first line of the specific trading company, combined with the analysis of the various modules of enterprise resource planning, we get the demand of the ERP system of the trading company in the actual economic activity.

The realization of the system is through the JAVA language development of the B/S structure of the Web application, the concrete application of the J2EE frame, Spring frame, database connection pool, AJAX and other technologies. With the help of J2EE frame, the system is designed to be a multi layer structure, so that the system is easy to upgrade and maintain, and the frame of J2EE ensures the system's performance. The Spring framework can be used for the overall management of the components, so that the program has a good readability. The system uses the database connection pool technology reasonably, which has greatly improved the performance of the system. AJAX has brought a revolution to the Web application, through which the system can make the system friendlier and enhance the user experience. Finally, the project needs analysis specifications, outline design specifications, summarize the detailed design specifications, system test plan, the basic scheme of ERP system design has been, and the industry of the ERP system has a deep exploration and laid the foundation for the follow-up research work started.
