Research On Integration Framework Of Waterage Based On EAI

Currently, the waterway administration of transport have gradually developed their own management information system. Because of lack of integrated planning, the problem of Information Island comes out with the difference in the respects of development platform, technology and database management system. As a result, these systems can't connect and share information with each other, or supervise the whole waterage system, which seriously affected the efficiency of waterway transport.The research background of this paper is the real project of waterage platform framework in Dalian harbor group. With the ideology of Enterprise Application Integration as the starting point, A design and research to the integration framework of waterage is proposed by combining the advantages of J2EE and web services which are mainly used in Enterprise Application Integration. With a view to that some information management systems of harbor are difficult to upgrade and modify, and considering that Enterprise Application Integration based on web services will cause serious inbreak to isomeric system which may bring huge volume of work, correlative technology and mechanism of J2EE are adopted in this paper. The problem of integrating the isomeric resource is solved by using JCA. Meanwhile, according to the requirement of sharing information for this integration framework, the isomeric data sources of each management system are integrated by using mapping model that based on schema mapping of XML. Based on the sharing information includes not only the structural data stored in database, but also half- structural and no-structural that stored in file system and HTML/XML document, this paper integrates the isomeric data source, accomplishes information sharing and data integration assisting application integration by using integrated data model based on XML and makes use of global mapping and local mapping.The research and application of waterage integration framework solves the data integration and share problem of distributed and heterogeneous databases, significantly increases the work efficiency of waterway administration. Because the system application is general, it is favorable to the design and development of integration platform in the other transportation industries.
