Design And Implementation Of Power Corporation Portal Based On Portal Technology

With the development of Internet from the90s,the computer system gradually entered Internet time.The global information system,which takes the Web website as the core is widely establishing.Enterprises of all kinds of internal information systems are also gradually improving,but the new question appears. Various services ability of manufacturers is actually irregular, so that the cost of usage and maintenance is expensive; what’s more,users need to log into different systems repeatly, the operation is tedious, and the efficiency is limited; users can not get the booked information according to the need; most of all,the existing systems lack cooperation with users and so on. Therefore, how to re-integrate various resources of different information systems, link the isolated information effectively, and access the systems easily through a "port" is becoming the most important issue of the developing information systems.The appearance of the Portal technology may be a good solution of this problem. The Portal takes users as center, provides the unification the user to login, realizes the information centralism visit, and integrates with office workflows integrated business environment. Using the Portal technology, the user may conveniently integrate kinds of information which is requisite in a unified tabletop window. According to the function provided by the Portal, a unique information Portal can be customized for the users by the managers, the required information needed by all the systems can be got together effectively in a unified Web browser, and we also can establish the corresponding accessing operation jurisdiction according to user’s classification.This dissertation is precisely based on above-mentioned context, refers to the actual research project, analyzes the research progress at home in the current time, gives a in-depth study on the basic theory and technology of Portal technology, including the J2EE technologies, Web services technology, Liferay Portal platform, JSP, etc. Finally design and implement an information services Portal used in the power corpration, and shows the system’s architecture, the module function, the system operation succession flows, and the implementation of the key technologies of the system.The completion of the information services Portal has the extremely important meaning for the development of our information Portal, and it will promote the development of the integrated and self-controlled system for information services.
