Research on Gas Field Product Application Integration Model Base-on GIS

Although GIS application integration system has not officially formed, the distributed GIS application integration is the main means to implement the seamless integration between GIS and applications. This paper studied on the current situation of enterprises GIS application integration, and proposed an Loose Model Application Integration (LMAI) strategy based on meta-driven, defined the concept model and algorithm of application integration in loose coupling mode, designed the system integration framework of meta-model and applications, established the common application integration interface employing the Application-Oriented Component (AOC), developed the application integration system in GIS loose coupling mode underlying the Metadata-driven. Focusing on the GIS actual needs in gas field area, the effective integration and transmission query between GIS and the gas field professional application were implemented.
