Oracle RDBMS History Over the Years

===Oracle Database 10g Performance Tuning Tips & Techniques
Here’s a timeline of how things progressed:
■ 1970 Dr. Edgar Codd publishes his theory of relational data modeling.
■ 1977 Software Development Laboratories (SDL) formed by Larry Ellison, Bob Miner, Ed
Oates, and Bruce Scott with $2,000 of startup cash. Larry and Bob come from Ampex[@more@]where they were working on a CIA project code-named “Oracle.” Bob and Bruce begin
work on the database.
■ 1978 The CIA is the first customer, but the product is not released commercially. SDL
changes its name to Relational Software Inc. (RSI).
■ 1979 RSI ships the first commercial version, Version 2 (there is no V1 shipped because
of fears that people wouldn’t buy a first version of the software) of the database written
in Assembler Language. The first commercial version of the software is sold to
Wright-Patterson Air Force Base. It is the first commercial RDBMS on the market.
■ 1981 The first tool, Interactive Application Facility (IAF), which is a predecessor to
Oracle’s future SQL*Forms tool, is created.
■ 1982 RSI changes its name to Oracle Systems Corporation (OSC) and then simplifies
the name to Oracle Corporation.
■ 1983 Version 3, written in C (which makes it portable), is shipped. Bob Miner writes
half, while also supporting the Assembler based V2, and Bruce Scott writes the other
half. It is the first 32-bit RDBMS.
■ 1984 Version 4 is released. First tools are released (IAG –genform, IAG-runform, RPT).
First database with read consistency. Oracle ported to the PC.
■ 1985 Versions 5 & 5.1 are released; first Parallel Server database on VMS/VAX.
■ 1986 Oracle goes public March 12th (the day before Microsoft and eight days after
Sun). The stock opens at $15 and closes at $20.75. Oracle Client-Server is introduced.
First client-server database. Oracle5.1 is released.
■ 1987 Oracle is the largest DBMS company. Oracle Applications group started. First
SMP (symmetrical multiprocessing) database introduced.
■ 1987 Rich Niemiec along with Brad Brown and Joe Trezzo working at Oracle
implement the first production client-server application running Oracle on a souped-up
286 running 16 concurrent client-server users for NEC Corporation.
■ 1988 Oracle V6 released. First row-level locking. First hot database backup. Oracle
moves from Belmont to Redwood Shores. PL/SQL introduced.
■ 1992 Oracle V7 is released.
■ 1993 Oracle GUI client-server development tools introduced. Oracle Applications
moved from character mode to client-server.
■ 1994 Bob Miner, the genius behind the Oracle database technology, dies of cancer.
■ 1995 First 64-bit database.
■ 1996 Oracle7.3 released.
■ 1997 Oracle8 is introduced. Oracle Application Server is introduced. Applications
for the Web are introduced. Oracle is the first Web database. Oracle BI tools, like
Discoverer, are introduced for data warehousing. Tools have native Java support.
■ 1998 First major RDBMS (Oracle8) ported to Linux. Applications 11 shipped. Oracle is
the first database with XML support.
■ 1999 Oracle8i released. Integrates Java/XML into development tools. Oracle is the first
database with native Java support.
■ 2000 Oracle9i Application Server is released at it becomes the first database with
middle-tier cache. Launches E-Business Suite, wireless database with OracleMobile,
Oracle9i Application Server Wireless, and Internet File System (iFS).
■ 2001 Oracle9i (9.1) released. Oracle is the first database with Real Application
Clusters (RAC).
■ 2002 Oracle9i Release 2 (9.2) released.
■ 2003 Oracle at France Telecom is #1 on Winter Group’s Top Ten in DB size at 29T.
■ 2003 Oracle 10g comes out—grid focused, encrypted backups, auto-tuning, and ASM.
■ 2005 Oracle RAC at Amazon hits the Winter Group’s Top Ten in DB size at 25T.
■ 2005 Oracle buys PeopleSoft (includes JD Edwards), Oblix (Identity Management), Retek
(Retail) for $630M, TimesTen (in memory DB), and Innobase (InnoDB Open Source).
■ 2006 Oracle buys Siebel for $5.8B, Sleepycat Software (Open Source), and Stellant
