Abstract—This paper describes the contribution to the Near real time ETL process, which shows way, how to maintain real time ETL process automated (without human – database administrator interference), in cost of reduced accuracy rendered by level of trust. 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. Result is showed on real data of a small company engaged in the sale of computer components, which expands the market for Internet sales and there is need for fresh data using business data warehouse containing real trade data.
Index Terms—Knowledge discovery in databases, extraction transformation loading, real time, business, data warehouse.
