It should be to no one’s surprise that ETL is a process that should go out the door. If you read my two prior posts, you will see how newer databases that employ export functionality provide far better ways to capture data and send it data warehouses.
The difference in data quality is stark. Through an ETL process for capturing data and loading it into databases, you have to work through several sources, some of which you may never have the data you need. Sometimes it feels like you are a magician for making data appear. Then you have the export process which sends all data, that you choose, in as raw as a form as possible for the data gurus to play around with it an mold it into terrific stories.
