Research And Development Of Distributed Application System

Outside country, the research and development of distributed application system have already proceeded early. Now, abroad distributed application system has already presented the next points, such as many layers of structure, face to the object, cross platforms, function can be easily enlagerment, system can adapt to use of big and complicated etc. The distributed application system that has the above characteristics has already been widely used. And new technology and development model have already become developement standard in reality But in the country, the research and development of distributed application system should be placed in start stage. But the distributd application system can face kinds of questions , such as, the rate of development is low, transplant badly, and enlargement is not put into the reality easily etc. And this distributed application system need procedure member to acquaint of kinds of knoweldge , namely he must necessarily make interface design , and also necessarily must understand busniess logic , and it is difficult to him. These things have not already more and more adapt to our country development of society and economic.In all, level of country inside and outside has margin in this way.This research will get with new technology of outside country .By learning and creating , the distributed application system matching state of our country is done . Development will be according to need of software engineering . Namely, the first step is need analysis , and this step has already been completed. Next step, the system should entering a norm development. Draw out the preface diagram and make it clear that each mold piece is how to be done .And each mold piece adopting with technology . At last each mold piece is tested. This development intend to adopt to technology that matching the J2EE norm of the American SUN Microsystems corporation , and use JSP, JavaBeans, Servlet, JDBC etc. The J2EE norm has already been used widely outside country and become development norm in reality.When the research is finished, it will realize a system of many layers of structure, facing to the object, crossing platforms and function can be easily enlagerment. The technology of distributed application system inside country would been reformed , and rise to show the model . Because inside country the distributed application system have some questions, this research create the reform project in a whole.
