Maybe the distinction between "natural" and "synthetic" would be clearer if we changed the labels. How about "external" versus "internal"? This still begs the question of whether I mean internal to the database or internal to the application and the database. But maybe it's a step in the right direction. How about "conceptual key" versus "logical key"? Received on Mon May 18 2009 - 19:15:44 CEST
