Hi Fernando.

So far I've being using SQL passthru for my apps when needed to access SQL Server, Oracle etc, but always brought selected data into VFP cursors and used them.

My problem is that I don't know how to build such an application, and even know how to start!

You may want to download the "Class Based Data Management" white paper and examples from our web site. Our data classes are a wrapper around SPT. They may help you to get started.
