Database Metadata Processing Based on CWM and EMF

In light of the heterogeneous of various database metadata as well as the field model to package metadata and the table structure to storage metadata require established by a mass of manual work,this paper puts forward database metadata processing based on Common Warehouse Metamodel(CWM) and Eclipse Modeling Framework(EMF),including getting,packaging,expansion,persistence and so on,as well as the realization of the field model and the generation of table structure.Results prove that database metadata processing based on CWM and EMF can solve the heterogeneous of database metadata and replace the manual work to build field model and table structure,and reduce the workload.
