Research Of Production Engineering Data Integration Platform

The subject of this paper is from technology research institute, Liaohe Oilfield, the actual drilling project - production engineering data integration platform. The project on construction of production engineering information systems, development of decision support systems, exploration data system, the oil plant systems, such as integrated production systems to provide users with a unified data query interface to achieve data integration, data sharing and data real-time query.In this paper, data integration technology for research, through analysis of existing data integration platform problems that exist in the light of Liaohe Oilfield production engineering of the status quo, give a kind of middleware-based data integration platform architecture and its implementation method. The platform use the existing development system middleware OGSA-DAI, and OGSA-DAI improve some modules of OGSA-DAI, the existing database systems integrate heterogeneous data sources will be packing become a grid service, through which Grid Services, Grid implementation of the database to share resources.Query decomposition and query optimization are the keys to data integration platform, which is directly related to the platform for the correctness and availability. In this paper, In accordance with Liaohe Oilfield production engineering characteristics of existing databases, give the query decomposition of the basic strategy and the query decomposition algorithm based on querytask tree. And data sources based on local cost and communication cost,improve the Prim algorithm, give a price based on the query optimization algorithm.
