摘要：

First we described ETL as a part of KDD, what is Real time ETL and problem how to achieve real-time in real world. In next part we give several (near) real time approaches with their advantages and disadvantages and then we present our contribution to near real time ETL with new architecture containing equation for calculation the level of trust.
