A data object is simply a component that talks to the data store (VFP tables, SQL Server, etc). It contains all the actual SELECT, INSERT, UPDATE, and DELETE commands. My data component is a non-visual class (based on Session). Don't have properties for each field. That greatly limits the component. Instead, pass the data around using ADO or XML.
