I might add to this thread that you will find a great deal of the power of SBPro in the ability to handle many edits and relations in the file definition or Data Dictionary. The capabilities in SBPro to extablish much of your relational integrity concerns in the file definitions is one of it's more powerful features. You are on the right path in trying to understand the basics of relational system design, especially understanding the concepts of entity-attribute relationships and the concept of a 'subject database', along with the idea of data driven design: define the data requirements first, design the files, then begin application development. It will save a great deal of application re-write and 'patching' later. Fortunatley, SBPo is totally forgiving about file changes and additions later on, as opposed to some DBM's that are very sesitive to changes in file structure. – via Whap!
