| The purpose of State Grid Corporation of China(SGCC) "SG186"project is that, constructing a integrative enterprise information platform, develop eight application systems, establishing six safeguard systems. The integrative enterprise information platform is composed of information networks,data exchange,data center,application integration, enterprise portal. Among the rest, data center and enterprise portal are the start-up project. Shandong Electric Power Corporation(SEPCO) enterprise portal system is the experimental project in province corporation layer.The goal is that, integrating the all kinds of running information system by page layer, improving the security, providing a uniform convenient individuating interface page for users, effecting great value of the running information system,finding a "way out" for the next data layer integration and application layer integration. After the enterprise portal system is builded, the running information system merged into the portal by Web Service or other interface technology, the new information system will be builded according to the portal criterions,and merged into the portal as soon as it begin to run.In the project, through introducing the technology of Single Sign On,Porrlet etc., users don't need repeatedly input User name, Password , eliminating the "Information Island" from the point of view of page interface by extracting the important "Page"from the "Information Island" and displaying it in the portal; through introducing the technology of Contents Management, Individual Customization, Automatic Apperceiving, the approach of getting information becames flat, decreasing the times of clicking the mouse,displaying the individual customization page according to the user's different requirement; through introducing the technology of User Authentication, Directory Service, achieving the user management of visiting the portal,ensuring that a user can only visit the accredited information, enhancing the security of information system.Information portal technology is a newer technology recently years.It is very beginning phase developing information system by Information portal technology, Neither mature system methodology nor method of the Information Portal System Requirement Analyse can be followed. This paper presents the difference of the method of Requirement Analyse between Information Portal System and general Management Information System, establishs the method of requirement analyse for this project according to the matter of fact. Based on the Information Portal System Rules of State Grid Corporation of China(SGCC),designing the architecture of SEPCO Information Portal System. General design is made by starting with the User Interface Architecture. This paper presents implement technology path of the Information Portal System Architecture and the characteristic of function difference between in Information Portal System and other Management Information System.Shandong Electric Power Corporation(SEPCO) Enterprise Portal System reachs the expectant goals, solving the problem of visiting hidden discommodious information, enhancing the security of information system., integrating the all kinds of running information system by page layer, effecting great value of the running information system, providing a uniform convenient individuating interface page for users. The majority of users think it more convenient and fast by the portal. In most of scene, the times of visiting information is fewer than three, the response time of a Portlet is fewer than six seconds. The specialty departments hope that the running information systems of developing by themselves are merged into the portal. The portal is becoming a "way out" for system integration. |
