Data Warehouse & ETL testing

Never ever test manually again! Using BiG EVAL you automate the test processes for your data warehouse system and the ETL or ELT processes.

Use Case DWH und ETL testen

BiG EVAL takes away the manual effort from testing your ETL or ELT processes and your data warehouse. This is done by comparing and checking test data between the source systems, the staging area, the data warehouse and all components in between. Exactly the way in which you would do it manually – but automated.


Choose out of a predefined set of testmethods and -algorithms or create your own by using a database query language, C# or even R.
