Advanced ETL Processor extracts data from any database, transforms, validates it and loads into another database automatically. A unique technology called "What You See Is What You Load" saves a lot of time during testing and design of validation and transformation processes. It shows you how the data will be transformed and loaded into the data warehouse or database without actually loading it. At any time, you can press the 'Preview' button and see what the results of an ETL flow would look like.
