Definition of: Oracle database





A relational database management system (DBMS) from Oracle, which runs on more than 80 platforms. Oracle was the first database product to run on a variety of platforms from micro to mainframe and were introduced in the late 1970s.




The Oracle database is Oracle's flagship product, and version 11g was introduced in 2007.

The Oracle "i" and "g" Versions

Starting in 1999 with Version 8i, Oracle added the "i" to the version name to reflect support for the Internet with its built-in Java Virtual Machine (JVM). Oracle 9i added more support for XML in 2001. In 2003, Oracle 10g was introduced with emphasis on the "g" for grid computing, which enables clusters of low-cost, industry standard servers to be treated as a single unit.
