Sales Management Information System Design Based On J2ee Architecture And Realization

The traditional enterprise management information system mainly adopts 2-tier architecture (C/S model). C/S model is a good method to build software system in a specific and independent environment. But with the enlargement of enterprise business and the request of Internet development, nowadays, the software architecture of the enterprise management information system is a distributed multi-tiers software architecture. J2EE provides a multi-tiered distributed model which has reusable components. Data exchange based on XML, and security pattern and traction service. The thesis uses J2EE to design a flexible, scalable automobile sales management information system.The thesis makes an overall study of J2EE architecture technology, services etc. A multi-tiered distributed architecture based on J2EE and MVC design pattern is brought forward, which has the advantages of both J2EE and MVC. The architecture separates presentation layer from business layer. Which satifies the requests of different users. Based on the research. We educe the overall design of Automobile Sales Management Information System. Based on the overall design, the thesis realizes the payment method module and verifies the rationality of overall design.Based on java components, the system develops the business layer, enable the system flexible. Imported the multi-tiered distributed architecture based on J2EE and MVC design pattern, enabled the system design more clear. The browser pattern make the client simple, the system's maintance quite easy. The system solves the needs well, meanwhile, provides a reference model for other similar system.
