#### Xerox Global Services

The product is easy to learn and once a developer understands the ETL way for solving the problem at hand, the developer's productivity will increase. Even our DBAs now uses the ETL software to quickly create solutions instead of SSIS or .SQL jobs.

#### SwissBanking

I used Advanced ETL Processor in 2 Enterprises for many business processes and Business automation (outside finance department). I did not find any other tool with so many functions and broad flexibility for that Price! If you need support for bugs or solution design you will get it very fast. Best Support I have ever seen.
