All the ETL vendors say the same thing: “our biggest competitor is custom code and stored procedures”. There are still a large number of organizations building data warehouses without using an ETL tool, writing their own, mostly very complex, SQL statements, often difficult to maintain. This is not very smart if you realize that these tools can increase productivity by a factor of three to five. Two of the most important features in this case are that these tools are completely meta data driven, and work with an easy to understand graphical user interface (GUI).
