Not to dwelve too far into Oracle hagiography but,

>During the 1970s, after a brief stint at Amdahl Corporation, Ellison began working for Ampex Corporation. His projects included a database for the CIA, which he named "Oracle". Ellison was inspired by a paper written by Edgar F. Codd on relational database systems called "A Relational Model of Data for Large Shared Data Banks".[10] In 1977, he founded Software Development Laboratories (SDL) with two partners and an investment of $2,000; $1,200 of the money was his.

It's really not clear from the first few hits off Google what his role was in developing Oracle, the application, but he's not like, _untechnical_.
