The Research And Design Of Enterprise Architecture Based On J2EE

With the wide application of web technology,lots of enterprises urge to construct web business systems.Although these business systems vary with special business logics,but in the aspect of software development,the process of many systems' development are almost the same. Faced with similiar web business systems,how to reduce technical repeating work,it is vital to improve software production.A prime resolvent is to design and develope a common application framework, hiding details of implementation in technique and forming a standard process of software development and letting developers focus their mind on the analysis and implementation about business logic.This paper introduces the standard for developing multitier-based enterprise applications and designs a kind of common application framework. The framework encapsulates a large amount of codes between layers.Developers need not to consider how to pass data between tiers and only implement standard interfaces according to particular business logic,then rapidly develop software.The writer also summarizes common business methods from general business logic and makes use of metadata to generate source codes in batches,so the efficiency of develop is greatly improved.
