Design and implementation of special ETL pattern
LI Wei-hua · Computer Engineering and Applications Journal · 2010
A special ETL subassembly is designed for command Decision-making Support System(DSS)a,nd then it puts for-ward a construction model ofETL + Meta-knowledge Base + interactive environment.It is modeled based on CWM to op-timize the metadata extraction of ETL and reduce development cycles.Data transformation which based on domain knowl-edge and interactivee,xtensible environment brings advantagest,hat increase efficiency for data transformation and realize com-plicated transformation logict,hen it can give references for other DSS to construct their own ETL subassembly.
