Aiming at the characteristics of AP model,based on the formal definition of objects in meta-models,this paper proposes an improved design model and an optimized algorithm for mapping conceptual models to logical models.The algorithm can map the simple source or the multi-source models in the foundation of data Extract-Transformation-Load(ETL) workflow,and raises the efficiency of concurrent execution of state node.Experimental result proves that this method provides good foundation for the design of ETL based on model driven and rapid realization of ETL in data integration.
