Hello Everyone:
I need to know if there is any tool which can be used to for post migration ETL testing? The ETL has been written using sql scripts to move the data from Legacy database to a new database and both have different database structures We need to test the tranformed data for accuracy and check for data quality and quantity after the ETL process is executed.
I have questions about the following:
1.what should be the best approach/ best practices to test the data in the new database after transformation?
2. I would like to know if there is any tool which can be used to compare the data in old vs new database (both having different structures) ?
Thank You all.
