Note however that Daniel isn't referring to the Ingres *product* but to the Ingres research project in the early 70's (Stonebraker e.a.). Besides the Ingres product, a number of other commercial products were based on this research (Sybase, NonStop SQL etc.). In the early 90's the Sybase code was licensed to Microsoft. http://en.wikipedia.org/wiki/Ingres
