I am not talking about masking which you could also do and currently do in most cases with encryption, I am talking about moving large amount of personal data from different sources and making sure the final data is actually valid. Teen agers should be alive and dead people should remain dead. That is ETL if your employees are not skilled you need Informatica. Informatica in most Enterprise implementation is one million dollars.
Then making sure that data cannot be moved without escort. And in the VA case only encryption would have made the loss limited not masking.
it is an in-situ update process and does not need other relational databases to succeed.
The tool in the link below only support SQL Server some versions and Oracle some version with DB2 edition in development so it is RDBMS versons dependent.
