Abstract: 
This paper introduces variable geometry database (db) keys and their subkeys, both mathematically and in db terminology, provides an algorithm for assisting their discovery, characterizes it, and presents methods for enforcing variable geometry keys and their subkeys in db applications using SQL embedding event-driven programming languages, with an example in MS VBA.
