J2ee-based Trading Company Erp System Design And Realization

Without taking into account policy preferences and potential trade monopoly situation, trading enterprises, due to occupy the length of the shorter supply chain, business had been relatively low, has always belonged to the external environment, complex, full and intense market competition, high-risk sector. In the global economic liberalization and internationalization of the background, each enterprise in order to deal with such situations, the need for all aspects of corporate resources in an effective and fast integration and planning in order to achieve expansion of the overall business performance, reduce costs as the goal. And how to meet the relevant requirements of trading enterprises is a long plagued the industry enterprises.In this paper, based on the specific characteristics of the trade sector and the special requirements of relevant enterprises, through a comprehensive study of the basic principles of ERP's, ERP technology development and application of the status quo at home and abroad, combined with features of trading enterprises, and information problems in the process, pointing out that trade enterprise application ERP Technical necessary and feasible; and from the theoretical analysis and system implementation to do the following two aspects:First, through a comprehensive literature analysis, to explore the basic principles of ERP's, ERP technology development and application of the status quo at home and abroad, combined with features of trading enterprises, and information problems in the process put forward in line with requirements of this country's trade industry, the overall framework of ERP systems, function modules and the modules for data integration model, and each module in detail analysis, design one and program development.Secondly, through the front-line staff on specific trading company research, combined with enterprise resource planning analysis of each module, has been real economic activity in the trading company ERP systems. And on this basis, proposed to sell, purchase, inventory, financial module as the core ERP system to realize the optimization for the trade sector to achieve an intelligent message to send, stock alerts, order alerts, multi-search and so on.System developed by java language B/S structure of the Web application, specific application of the J2EE frame box, Spring framework, database connection pooling, AJAX technologies. With J2EE frame box, and system design into a multi-layered structure, allowing the system to facilitate loose coupling upgrades and maintenance, at the same time, J2EE frame of the rack to ensure the system performance. Through the Spring framework can manage the whole of the components, make the program a good readability. Systematic rational use of database connection pool technology, making the performance has been greatly enhanced. AJAX applications to the Web has brought a revolution through which you can make the system more user-friendly, to enhance the user experience.Finally, the project needs analysis specifications, outline design specifications, detailed design specifications, system test plan summary, ERP system design has been the basic program, and industry-specific ERP system has in-depth exploration of the follow-up study laid the foundation for the work started.
