SQL Data Compare is the industry standard tool for comparing and synchronizing the contents of two databases. Used by over 45,000 DBAs, developers and testers, it is recognised as a very high quality, yet simple, piece of software. SQL Data Compare is used when the data between two databases has got out of synch, and saves huge amounts of tedious work in synchronizing them. Others use it as a tool for QA, documentation and verification.
