Traditionally ETL(Extract, Transform and Load) processes served a key role in any organizations’ DataWarehouse strategy. However, better techniques and technologies are starting to replace the role of the ETL. One such technique is Data Federation. In layman terms, it means to logically group all the data sources and present them as an integrated system, thereby avoiding any physical data movement. In other words, physical data movement is now being replaced by logical organization. At DataCaliper, our approach to Data Federation has been at a customized level. Data Federation is currently being considered only when existing data is too vast, diverse and dynamic that ETL cannot be implemented. However, our clients have boldly marched ahead in implementing Data Federation. We’ve transformed traditional database servers into Data Federation Servers and have helped organizations leap ahead in their data management initiatives bypassing the Data Warehouse implementations.
