ABSTRACT:
There are two distinct types of data: dynamic and persistent. Dynamic data is in flux; this is where transactional data begins. Persistent data is fixed. It's what it is and will never be anything else. Just because data is dynamic doesn't mean it starts and dies within an RDBMS. Structured database data starts as dynamic, but at some point it becomes a nonchanging record. It's persistent. You may have reasons to keep it inside a database forever (although I doubt they're valid ones), but those records are still persistent; they are what they are.
