I did some research and It has nothing to do with Oracle (the database people).
KVQuest was started by James (Jim) Heaton in 1981. KVQuest was originally incorporated in 1981 as Oracle, Inc. It had and has no relationship to Oracle Corporation, the database and applications company. In 1999 Oracle, Inc. changed its name to KVQuest, Ltd.
In addition, from 1987 through 2004 KVQuest and AMR Research operated a joint consulting activity called AMR Consulting. That joint agreement ended December 31, 2004. AMR Consulting clients are now served by KVQuest directly.
