World top billionaires

..........................................................................................................................................................................

Lawrence (Larry) Joseph Ellison (born August 17, 1944) is an American billionaire and the co-founder and CEO of Oracle Corporation, a major enterprise software company.

During the 1970s, Ellison worked for Ampex Corporation. One of his projects was a database for the CIA, which he named "Oracle".

Ellison was inspired by the paper written by Edgar F. Codd on relational database systems named "A Relational Model of Data for Large Shared Data Banks." He founded Oracle in 1977, putting up a mere $2000 of his own money, under the name Software Development Laboratories (SDL). In 1979, the company was renamed Relational Software Inc., later renamed Oracle after the flagship product Oracle database. He had heard about the IBM System R database, also based on Codd's theories, and wanted Oracle to be compatible with it, but IBM made this impossible by refusing to share System R's code. The initial release of Oracle was Oracle 2; there was no Oracle 1. The release number was intended to imply that all of the bugs had been worked out of an earlier version.

In 1990, Oracle laid off 10% (about 400 people) of its work force because of a mismatch between cash and revenues. This crisis, which almost resulted in Oracle's bankruptcy, came about because of Oracle's "up-front" marketing strategy, in which sales people urged potential customers to buy the largest possible amount of software all at once. The sales people then booked the value of future license sales in the current quarter, thereby increasing their bonuses. This became a problem when the future sales subsequently failed to materialize. Oracle eventually had to restate its earnings twice, and also to settle out of court class action lawsuits arising from its having overstated its earnings. Ellison would later say that Oracle had made "an incredible business mistake."

Although IBM dominated the mainframe relational database market with its DB2 and SQL/DS database products, it delayed entering the market for a relational database on UNIX and Windows operating systems. This left the door open for Sybase, Oracle, and Informix (and eventually Microsoft) to dominate mid-range and microcomputers.

Around this time, Oracle fell behind technically to Sybase. In 1990-1993, Sybase was the fastest growing database company and the database industry's darling vendor, but soon fell victim to its merger mania. Sybase's 1993 merger with PowerSoft resulted in a loss of focus on its core database technology. In 1993, Sybase sold the rights to its database software running under the Windows operating system to Microsoft Corporation, which now markets it under the name "SQL Server."

In 1994, Informix Software overtook Sybase and became Oracle's most important rival. The intense war between Informix CEO Phil White and Ellison was front page Silicon Valley news for three years. Ultimately, Oracle defeated Informix in 1997. In the same year, Ellison was made a director of Apple Computer after Steve Jobs came back to the company. Ellison resigned in 2002, saying that he did not have the time to attend necessary formal board meetings. In November of 2005, a book detailing the war between Oracle and Informix was published. "The Real Story of Informix Software and Phil White" provides a detailed chronology of the battle of Informix against Oracle, and how Informix Software's CEO Phil White landed in jail because of his obsession to overtake Ellison.

Once Informix and Sybase were defeated, Oracle enjoyed years of industry dominance until the rise of Microsoft's SQL Server in the late 90s and IBM's acquisition of Informix Software in 2001 to complement their DB2 database. Today Oracle's main competition for new database licenses on UNIX, Linux, and Windows operating systems is with IBM's DB2, the open source database MySQL (bought by Sun in 2008), and with Microsoft SQL Server (which only runs on Windows). IBM's DB2 still dominates the mainframe database market.

In 2005, Oracle paid Ellison a $975,000 salary, a $6,500,000 bonus, and other compensation of $955,100.

Forbes listed Ellison's 2005 net worth as $18.4 billion, making him one of the richest people in America, and the ninth richest man in the world. For a short period in 2000, Ellison was the richest man in the world. In 2006, Forbes ranked Ellison as the richest Californian. In interviews, Ellison notes that his actual wealth — money that he is realistically free to spend — is more like $2 billion, and that if he tried to sell all of his Oracle stock, its price would fall to zero.[citation needed] Ellison also owns large stakes in both Salesforce.com and NetSuite.
