There is a problem in the process of data analysis, which is related to their extraction and preparation.This problem is the consequence of a necessity for integration of heterogeneous structures both in structure and format.The technical solution to this problem is to use ETL-systems that automate processes of extraction, transformation and loading of data into a storage according to strictly defined rules.To date, scientific research in this area focuses on increasing performance and documenting the semantics of the process for its reuse.The paper presents results of a review and analysis of actual solutions in the field of extraction of heterogeneous data of large volume.
