Implementation Of SOA Based Enterprise Portal Integrated System

With the rapid development of enterprise information construction, enterprises have built more and more operational systems, and the phenomenon of information isolated island is increasingly more serious. Those heterogeneous enterprise applications encounter many difficulties in information interaction and information sharing, and even cause many problems because of information inconsistency, thus the requirement of enterprise application integration occurs. Meanwhile, enterprise application integration also has many disadvantages, such as great difficulty, high risk, and long period. To resolve these problems, enterprises should establish new enterprise application integration architecture, so they can protect existing information assets at the most extent, reduce integration risk and shorten the integration period. In addition, they can respond to the requirements of new business and the alterations of old business more quickly. In this case, enterprise information construction will satisfy the increasing demand of business development.This thesis summarized the status and trends of enterprise portals, analyzed the key technologies and features of portal integration. On this basis, we take a company as example, combing the current situation of its information construction, providing a SOA-based enterprise portal integration solution. In this thesis, the demand of portal integration has been analyzed deeply, the functional features have been divided, and the system architecture and deployment structure has been designed under the concept of SOA. Meanwhile, this article discussed the design and implementation of unified users management, single sign-on, unified backlog, and leaders chart in detail, then analyzed the functional requirements of these modules, set forth the procedure of key features, and designed the database table models, and finally tested the system. The solution of this thesis has solved some problems of information isolated island, simplified the operation process of business systems, effectively improved work efficiency and the security of information systems. The system also provides a wealth of charts to show business data for leaders, which made analysts liberated from the traditional manual mode.In this thesis, the design and implementation of integrated enterprise portal system has been put into use in an enterprise group headquarters. Since running, the system is stable and reliable, has reached expected goals. This thesis proves that there is some practical guidance in how to construct a SOA-based portal integration system as the unified entrance of operational systems.
