Portal Lightweight Framework For Enterprise Data Integration, Design,

With the development of Information technology, enterprise IT construction is concerned by more and more enterprises.However, we must pay attention to all sorts of questions which in the informationization construction process:on the one hand, the informationization lets us place oneself in each kind of distributional computation environment, we must login many different systems and applications,the probability of making mistake and having security problems will be heightened along with the amount of the systems that we logged in, and the correctness of user authentication will difficult to ensure,the cost and difficulty of maintaining system will increase, too.On the other hand,along with the progress of enterprise information process, all kinds of enterprise information systems(EIS) are showing up, and the data amount of enterprise are increasing intensely. The different EIS is for certain different business purpose, yet these enterprise information systems are created separately and there is no interaction each other. so each EIS has its own GUI,data source can not be shared, at the same time it may cause the problems of data integrity. All these things bring a lot of troubles to the information acquisition and prevent IT construction and the enterprise from high speed development.Therefore, solution of Portal appeared, as an entry of unified information access, portal is widely used in system integrate to different systems, there are three main kinds of system integration: data integration, user interface integration and user integration. Placeholder mechanism helps to reach the goal of UI integration by abstracting various presentation of content in portal,portal provide customize service ,so that users have better experience in portal, portal adopt SSO(Single Sign-On) mechanism to solve united identity authentication.With the goal of solving enterprise data integration, this paper presents the lightweight architecture of data integration of minor department Oriented Portal through the needs which are driven by civil minor enterprise in building Enterprise Information Portal.Atfer deeply researching of portal's key technique, designed a lightweight frameworks,which is designed data integration's subframeworks based message proxy on it, therefore,not only has it characteristic of lightweight,but is the software system that loosely coupled. The lightweight frame not only designed an outstanding three greatest core module: customization, applications integration and SSO (Single Sign-On), but designed efficiently search engine which provide to strongly search service for the lightweight frameworks.Finally, all have the creative improvement of frame function in textual each detail for design, so that at various function frameworks is efficiently lightweight frameworks that have high performance better than other.
