Abstract: A lot of papers describe three common methods of data selection from primary systems. This paper defines how to select the correct method or combinations of methods for minimizing the impact of production system and common operation. Before using any method, it is necessary to know the primary system and its databases structures for the optimal use of the actual data structure setup and the best design for ETL process. Databases structures are usually categorized into groups, which characterize their quality. The classification helps to find the ideal method for each group and thus design a solution of ETL process with the minimal impact on the data warehouse and production system.
