Research on data integration of ordnance equipment training simulation system

The database of the existing ordnance equipment simulation training system is multiple.Its data format and service offered are also different,bringing about information passing different department difficultly.It's difficult to improve the equipment supporting between dispersive systems.This paper introduces a data integration patterns-data integration based on the data warehouse.Using the data integration model that can mask a variety of heterogeneous data stored in different databases,to solve simulated training sub-systems data sharing and exchange of issues,to achieve interoperability of data between the subsystems,security simulation training system for the realization of integrated data protection.
