Research On Persistence Framework Design Stategy Based On J2EE Distributed System

In the recent years, people gradually recognize that the object-oriented for the application of the technology of software has become a great milestone for the development of the software technology. In this paper we offer a designing project of the distributed persistence framework that is based on object-oriented technology and the distributed platform of J2EK that is now currently popular.The aim of the designing project is re-use and extensible. Realizing the lack of a good method of judgment for the software design in the past time, we give a judgment method that is the unified between the practice model and the software model in a certain level of abstraction. The designers can make a fast and an efficient judgment to tell the degree of the difference of the good and the worse in practicing the system by this method. This dissertation designs a persistence framework that has the advantage of more steadier architecture, better extensible, better practicability and direction. By mapping a system of warehouse management for enterprise between software models in our design work, the property of the distributed and persistence framework from the view of the software design is detail analyzed; the design pattern certified by former generation is also greatly applied. In the paper, according the principal of judgment for the unified of the certain level of the abstraction for the practicing model and the software model is applying during the design work, we consider the destination of re-use and extensible, and the characters of J2EE platform and the other newest technologies.
