Mocking Frameworks enable you to test your business objects. Data Driven tests often end up becoming more of a intergration test than a unit test, they also carry with them the burden of managing the state of a data store pre and post execution of the test and the time taken in connecting and executing queries.

In general i would avoid doing unit tests that touch the database from your business objects. As for Testing your database you need a different stratergy.

That being said you can never totally get away from data driven testing only limiting the amout of tests that actually need to invoke your back end systems.
