Research Of Intelligent Building Property Management System Based On J2EE Platform

With the development of computer and Internet technology, Internet has become an indispensable part in people's live and production. Each area of our society are trying to establish application system based on network, by using this way to implement the communication of information and the share of resource. As modern enterprises, if they want to adapt the variational environment, establishing a flexible and extensible enterprise information system based on Internet/Intranet is a necessary choice. By building an open environment for The property management system in intelligent building, which is based on web technology, overcomes restraints of simplex function and difficultness to integrate with other business system in traditional property system, establishes a dynamic controllable uniform integrative platform, supplies the advanced solutions of Electronic business for enterprise.The article first analysed the actions of property system in intelligent building, based on this, it analysed the functions in detail and get the material models. Then we designed the system framework based on J2EE platform as the models.J2EE provides the infrastructure of distributed application, which also is an advance platform of developing Web application based on J2EE components, such as JavaBean, Servlet and JSP. According J2EE multi-layer architecture, the model is composed of four layers, which includes client layer, Web layer, logic layer and data persistent layer. Logic layer provides the distributed service and includes business sublayer and persistent sublayer. Business sublayer implements business logic and persistent sublayer is responsible of operating with data source.As a solution, the model system takes on MVC pattern. Web layer build upon Struts framework. In logic layer, business sublayer employs JavaBean components to execute business logic;persistent sublayer adopts DAO design pattern to operate database. In addition, the Ajax technology is introduced to improving the flexibility of Web Site. By using this technology, we can produce a more flexible directory tree to fulfill the users' demand.Finally, this paper researched the problems of security and character coding of the system.
