Research And Application Of Procurement Management System Based On J2EE

Procurement management system provides enterprises a kind of service standard and flexible, and which purpose is improving business management efficiency. Making traditional procurement management electronical and computerizable, because of the whole management procedure completes at internal local area network, it ensures the security of information from physical structure.This dissertation takes user needs into primary consideration, I study the needs analysis, overall design and realization carefully. The system based on MVC design pattern, combine with Struts Spring and Hibernate framework of technology, namely SSH open source technology.Applications of widespread use of design pattern combines with mainstream database management system SQL Server2008has advanced nature both in theory and practice.The main works of dissertation as follows:(1) Research procurement manangement system existing in market, study the design idea and use of new technology. Learn the MVC design pattern, J2EE platform and SSH framework technology, search relevant material, provide theoretical support for the design of the system framework.(2) Detailed analysis of user needs, put forward overall scheme of design. Use Unified Modeling Language for describing system, devise the general framework of management system accroding to system design principles and functional needs, by using use case diagram, calss diagram and other images describe system framework, explain system functions.(3) According to the overall design, implement the system. Intergrate SSH technology, accomplish presentation layer, business logic layer, data persistence layer, to creat a startified, low coupling management system. Not only to achieve user’s needs, but also has a good interactive character docking with other systems.Through a comprohensive user needs analysis, overall design and implement. After accomplished the management system based on J2EE platform, in post-test and delivered to the actual test period, it reflects superio performance, thorough bussiness logic and favorable user experience.
