Matt,

CursorAdapters do *NOT* require a DBC -- eliminating that requirement was one reason for their creation. They're basically intended to replace remote views, which *do* require a DBC.

As it turns out, they're also a great way to create back-end independent business processes.

They can even be given the same names as your old DBF aliases to minimize code changes. You can then perform record based operations like SKIP on the cursors. If your forms are doing updates, you will have to recode those routines to send UPDATE commands to the server. It's not too bad.
