Commercial vs. Open-source Solutions:

“IBM DataStage” and “Informatica Power Center” are examples of Data Quality Commercial solutions that have extensive ability to handle very large data volumes in complex and heterogeneous environments. These products provide comprehensive features and functionality and therefore also require extensive training to use effectively. Considering the cost and the effort required in implementing these solutions, they are best suited for very large, complex and enterprise-wide systems.

On the other side of the market are the Open Source solutions, which have matured into viable technology alternatives. Talend, Pentaho and CloverETL are examples of open-source solutions available in this category. These solutions come in free as well as paid editions. Free editions are good enough for performing basic to medium level data quality functions. The paid versions of these tools offer some advanced features and customer support in addition to basic features.

These solutions are perfect mid to large organizations, and organizations can take data quality initiatives without investing much in earlier phases. If the requirements grow data quality teams always have the option to do the customization in open-source solution or can move on to their licensed versions.
