Design And Implementation Of Personalized Information Management Platform

Because of the rapid modern life rhythm and the frequent commercial activity, especially knowledge and information detonation, people need a fully, highly effective way to manage his timing and to organize the information to strengthen communication between people. Personalized Information Management Platform website helps people to be possible to enjoy the comprehensive personalized information management (PIM) services through Internet, SMS, WAP, GPRS and other platforms. People can inquiry and manage his personal information at any time anywhere through the computer, the cell phone, PDA and other information terminal. This platform combines the mobile Internet, the traditional Internet and the telecommunication resources into one. Centered with people, the platform integrates the enterprise, the government, the association, the public security, the traffic and various kinds of organizations together. Any person, at any time, any place can use any terminal through the website platform to exchange, inquiry and manage information. As to meet the requirements of the market, some viewpoints and opinions are brought forward about how to realize the Personalized Information Management System after analyzing and researching about the future and the potential business value of PIM service. According to performance requirement of the system, structural model is given out with the theory of the distributional multilayered structure. The thesis also studies and discusses about how to use the J2EE technology and the appropriate design pattern to realize the specific PIM system and to enhance the system performance. Object-oriented method is used to do the requirement analysis, and the use case model is shown. During the process of the development, the distributional n-tier construction design is used with MVC model and some of the J2EE design patterns which ensures the system with the security, the stability, extension, easy maintenance and fast response ability. Taking the Synchronization Setting module as an example, the paper gives out a detailed way of how to use J2EE technique in the construction of PIM platform. For the designing pattern of J2EE the paper exercises the Module-View-Controller scenario. In the model layer, business delegate and service locator pattern are used to capsule the business service. Front controller and command pattern are used in the control layer. View helper pattern is used in the view layer. These design patterns helps to reduce coupling degree between various modules of the system and makes the system to be easy to maintain and expand.
