>although i've been coding and using vfp6.0, i have never developed anything using true client-server technology. i am keen to get into client/server environment using ActiveX Data Objects and vfp6 as the front-end and initially as the back-end too but i have no idea what its all about. where (on the net) can i get basic / simple understanding of the concepts as also to understanding ActiveX Data Objects coding terminology in multi-user environment in vfp6.0 ?

You don't need ADO to perform a "real Client-Server" technology. You can use al so SPT & Remote Views.
