Application of data integration of multi-source heterogeneous
Chen Xi-lai · Journal of Chengdu University of Information Technology · 2009
In dealing with the heterogeneous data difference between the multi-databases the structure of heterogeneous data integration system,schema mapping,schema conflict and its solution,inquiry handling and data integration and data management are studied.The solution to the heterogeneous multi-database unification of middleware architecture is presented.The GAV is used in schema mapping,JAVA and JBoss4.2 are used in this system,JAVA is used to describe the algorithm,XML is used to describe the schema and schema integration.In the experiment the successful solution to the remove of the schema conflict,the disintegration of global inquiry and the handling of data unification are obtained.
