For those who aren't familiar with Ingres, let me outline where Ingres came from and what the technology is all about. The Ingres technology has been around for quite some time. It dates back to the early '70s at UC Berkeley, and was a project started by Michael Stonebraker, Eugene Wong, and a number of other very talented folks at Cal Berkeley. They are essentially perceived as the fathers of relational database technology. In the '80s, Ingres went from being an open source project, available under the Berkeley license to anybody who had the money for a source code tape, to a commercial entity, a company called Relational Technology, Inc.
