Research And Design Of A Based-J2EE Materials Supervision System Of Foreign Processing Trade Enterprise

This paper proposes a foreign processing trade enterprise material supervising system based on J2EE whose foundation is to fully research on foreign processing trade enterprise characteristic, demand, each kind of work flow, the service standard of the customs supervising and existing material supervising system. The management system based on multilayer structures is realized by designing and realizing each function and database, as well as analyzing solution to difficult questions. The system has been used in practice and received expected results.The system uses the MVC design pattern to analyze and design, which makes system development simpler and is easy to understand using object-oriented analysis and design. To confirm new input data, JavaScript with the regular expression match function is inserted the page and can be run directly in the client side, which both enhances the speed of response and reduced the server burden and the network current capacity. The single-layer relations design which simples the complex material relations and makes development and the maintenance easier is used to design the BOM table in the database. As system secure, mechanism of user authentication and the access control based on the role is used to ensure system own security, which binds two kind of security strategy, namely statement and programming. Moreover, it how to implement importing original data is analyzed and designed in detail.The system adopts J2EE as the distributional development platform to realize multilayered system structure of logical and the data lamination processing, which enhances not only system stability but also system extendibility.
