>My friend is starting a new project with VFP8 + SQL Server as a back end. Prior to that she worked with Visual FoxPro native tables and VFP6. She would like to see some samples of such applications and choose the right methodology for the project.

>Any ideas for the beginner, where should she start?

I'd suggest a free WhitePaper available at EPS:

--- Migrating Your Visual FoxPro Application to a Client/Server Platform ---
