>>>>Let me clarify. I am interested in writing a middle tier layer in VFP. The frontend will also be written in VFP. I am interested in splitting the app. in this manner to provide scalabilty so later on the backend database may be easily changed to a SQL Server , also the data may be accesible easily to other programs.

>>>>My question is that from the middle tier, how to return a set of records ?

>>>Hi,

>>>I think what you want is a view of the data, whcih gives you a set of records. Write your frontend so that it talks to the view of the data. This can be a local view of VFP tables. Later you can migrate the data to SQL Server but create a view with the same name as your local view.

>>>Codebook frameworks allow developers to switch from local to remote views quite easily.
