Im pretty sure its not the gang of four. I have a feeling this is a newer pattern. Where was it first published/mentioned?
Who's the author/creator of the Repository Pattern?
design patterns;repository
The earliest mention of it that I can find is in this paper, An Introduction to Software Architecture, by David Garlan and Mary Shaw (1994, first published 1993). That predates the Gang of Four by a year, so it's an older pattern rather than a newer one.Martin Fowler and Eric Evans have both mentioned it in their books and popularised it, but it's been around for a while.
