Trait Constellation


Key Achievements

He co-founded Software Development Laboratories in 1977 with Bob Miner and Ed Oates, the company that became Oracle, and took the lead as president in building a database business out of a consulting start.

Oracle developed and began selling an SQL-compatible relational database before IBM had an SQL product on the market, according to the National Research Council. Version 3, rewritten in C in 1983, let it run across many computer makers.

Oracle later grew through acquisitions, about $45 billion since 2004 by TechCrunch's count, including PeopleSoft for $10.3 billion and Sun Microsystems for $7.4 billion, and Ellison announced its public cloud service in 2011.


Moments That Reveal Them

To make the database portable, the company rewrote it in the then-new C language over several years and froze new features meanwhile; the essay says engineer Bruce Scott pushed for it and Ellison backed him against co-founder Miner's preference for a quicker VAX port.

This is consistent with a willingness to accept a long, costly technical bet. Risk Tolerance

In September 2008 he told analysts cloud computing was 'complete gibberish' and that Oracle would change little beyond some ad wording; in October 2011 he announced Oracle's own public cloud service.

This is consistent with a late change of direction after an initially dismissive stance. Adaptability


Turning Points

After the first years as a contract-software consultancy, the founders stopped consulting and turned to a relational database product built from IBM's published System R work, and the CIA became the first customer.

This is consistent with an ability to see a commercial opening in work that a larger company had not yet shipped. Opportunity Sensing
