Generally, "logical consistency" refers to things like, if you have an inventory part record that has a manufacturer id, the manufacturer table has that id in it. In other words, the set of files or tables are not 'broken' in the sense that you have data that refers to things that don't exist.

I know what it means in a logical system (that it's possible to derive a contradiction from the given premises) but I don't think I've heard the term used w.r.t. DATA statements. Can you provide a context for the question?
