other development, which was the INGRES project at U.C. Berkeley. The INGRES project had a language called QUEL. They started a company that implemented QUEL. QUEL fought SQL tooth-and-nail, and explained how QUEL was better than SQL in many different ways, and in fact it is better at doing aggregates. There are lots of areas where QUEL is better. Some people at Ingres now feel that the reason that they were less than successful is because they fought SQL rather than embraced it, so this gave Oracle a chance to differentiate themselves.
