Information Systems Based On Uml And J2ee Architecture Design And Implementation Technology

With the development of information system, more and more applications are required. The fields that it involved in are becoming broader,and the higher complexity of information system is incurred. But the complexity of the business management and the technical realization are higher to construct an application system which is reusable, flexible and expansible. This causes the technology of design and realization appears vital. The development of application system is extremely rapid, the system needs to maintain and expand frequently. Otherwise, it will be face with obsolete and danger which is eliminated . If we don't plan and design the system carefully, when in front of new demand, the system will be difficult to promote.If we can unite the design technology with realization technology very well. It will establish one system which is stable, reusable, extensible and maintainable. And reduce the difficulty of communication which is between designers and programmers. With the high-speed developing of information and comparing each kind of components of present J2EE framework ,the paper choose Struts for the web layer and Hibernate for the lasting layer to design and realize the General Enterprise Application Framework which unify the advantages of them, and describe the relations of the layers and realization in GEAF.It has huge semantic disparity between technical and actual demand of business which provides in J2EE.If we want to surmount this disparity, we must has one basic and clear understanding to J2EE and the reasonable architecture of concrete application domain system. UML may help to connect technology of J2EE with demand of business. UML is blueprint language of software. it can describe the principal element of complex system by visual, concrete, structural, and enable the design technology to achieve consistently with the code.The paper analyse the present majority problems which are in software exploitation,for example,the separation of design and code, designers and programmers can not communicate very well each other,the code and the design is not consistent after maintaining and enpanding in the long time and so on. Aim at these,the paper uses modelling tool of UML to join consistent design pattern into J2EE framework and generate system procedure code framework. Researching OOD and UML,analyzing the progress that set up designing model of UML and generate code. Finally,using an example to show designing and realizing progress of which is facing to framework of J2EE,explain the unite of UML and J2EE framework is a feasibility and high- efficiently designing method.
