There is a large number of heterogeneous and decentralized data information in the military information construction process.The correlation between the information cannot be easily determined,which formed isolated information island problem.In the view of the current situation,the program for integrating heterogeneous data sources based on military applications is presented.XML Schema is used for definition of global data model,XQuery is used as a query language,and data mapping technologyis adoptd to realize the in-formation integration in the military.Meanwhile,it uses of role based access control system strategy to enhance the overall security of the system.
