Enforcing Workflow Through Relational Integrity

Many computer systems involve stepping through a Workflow, or State Machine.  This session will look at a number of relational database design patterns, all of which come together in a database model for enforcing Workflow within the database in a way that is fully configurable.  Along the way we will look briefly at several possible designs for recording history, giving a passing nod towards Trees and Hierarchies as well.  After throwing in some advanced relational integrity concepts, we will bring it all together with some ideas for enforcing a State Machine in the database without the use of triggers, CLR assemblies and the like.  Sounds like pure, old fashioned fun for the whole family!
