Oracle: the company and the database. A timeline

Summer 1966
  • Ellison moves to Berkeley, CA. Works weekends as IBM systems programmer

  • Ellison leaves IBM and start working for Ampex (company invented the magnetic tape recorder).
  • Works in the terabit memory system project, code-named Oracle, funded by the CIA, at Ampex.
  • At Ampex, worked in a database management system for the PDP-11 minicomputer. A CODASYL database, modeled after Cullinet's IDMS mainframe database.

Larry Ellison read Don Chamberlain's papers on the System R and SQL language and decided to build a relational database management system for minicomputers.
Ellison (34 y/o), Bob Miner and Ed Oates founded Software Development Laboratories.
In the picture: Ed Oates, Bruce Scott, Bob Miner and Larry Ellison.
Bruce Scott, who would be hired upon the formation of the company, is the “Scott” in scott/tiger (tiger was Bruce’s daughter’s cat).

SDL signed a contract with CIA to continue working on a SQL-based relational database.
Oracle Version 1, written in assembly language, runs on PDP-11 under RSX, in 128K of memory.

Oracle made its first public offering of stock.
One of the principal reasons for Oracle's success was the 1986 emergence of SQL as the industry's standard language for relational database management systems, which in turn led to increased market acceptance of Oracle's SQL-compatible RDBMS.
Oracle releases SQL*Plus, SQL*Menu, SQL*Graph

In 1986 Oracle expanded its RDBMS product line and debuted another industry first, a distributed DBMS based on the company's SQL*Star software.
