I agree as I am correct.

Allow me to quote from:
http://www.referenceforbusiness.com/history2/49/Sybase-Inc.html

Sybase was founded in 1984 by Mark Hoffman and Robert Epstein. Hoffman had previously worked as an executive at a company called Britton Lee, which pioneered the field of database computing. He joined Epstein, who had helped to create an early relational program called Ingres while working toward his Ph.D. at the University of California at Berkeley. Together, the two set out to market a cutting-edge relational database management system (RDBMS), which would organize information and make it available to many computers in a network.

The origin of Sybase, with respect to concepts and architecture, is Ingres and thus it too is the underlying foundation of SQL Server.
