The processing procedure of the traditional ETL work flow is analyzed and studied.Based on JAVA
the optimized scheme of ETL work flow is presented
and it optimizes the traditional ETL performance
perfectly solves the problems about data fusion
data consistency and data synchronous update in the data integration processing procedure
and reduces bottleneck restriction and the processing time.The application proves that the optimized ETL flow scheme effectively reduces the time of the traditional ETL workflow with favorable application value.
