Research On Enterprise Portal And Enterprise Application Integration

Contraposing the problems of enterprise's information-based process , this paper provides an effective scheme of enterprise application integration's implement and enterprise portal's establishment. Enterprise Application Integration (EAI) provides an effective scheme for heterogeneous database integration to realize the share and the inquiry of information resources .Enterprise Portal (EP) is an approach to access enterprise applications and information synthetically as the important foundation to establish information platform for enterprises. The virtual database system based on affecting each self-existent database as little as possible can shield the heterogeneous data and integrate them to provide a good base for configuration of Enterprise Portal. According to the separating character and contents of the XML data, the paper represents different forms to different users from the same XML data to provide personalized services and represent content in browsers and wireless equipments by the Cocoon technology .The paper firstly introduces the basic concepts and the framework of EP and EAI, and detailedly describes the content of each part. Then the paper studies data-level EAI and XML technology pertinently, analyses the working principle and methods of data-level EAI, and studies the advantages of XML technology and its working principle in data representation. This paper provides the model according to the above research work. This model includes Single Sign-on (SSO) ,uniform authentication, uniform source management, configuration of personalization and management of representation polices. Application Integration sub system implements the integration of enterprise applications and information sources. The model provided here fully reflects the practical requirements and main problems in information-based process and takes the advantages of XML with good extensibility and feasibility.
