| During the process of the information, because the overall planning of information is not perfect enough, it results in many information islands. The one of focus of enterprise information is how to eliminate these information islands and implement application integration.Classical integration technique resolves integration among applications. Exactly, this technique resolves coarse integration among applications. Enterprise application shows that enterprise needs refine-grain integration which can implement integration of user-centred object-user-application, In this paper, a kind of object-user-business integration frame is proposed based on WebGIS by means of meta-data and meta-data-driven technique. By means of GIS space objects, The frame can integrate different users and businesses related to the user and interested objects. This integration frame has been applied to Daqing Oil Field, which resolves applications integration among multi-discipline and multi-business. At the same time, the integrated tools is designed and developed based on the model of the business integration which is constructed based on the logical framework of the integrated model by means of meta-data and meta-data-driven technique, which can implement the application of a customized oilfield business.The results of research show that this integration frame resolves refine-grain integration of a large scale enterprise complicated applications based on WebGIS. This refine-grain integration frame is able to be applied to other area application integration. |
