Meaning of ‘i’,‘g’ and ‘c’ in Oracle Database Version

 

Oracle 8i, 9i

The ‘i’ in oracle 8i and 9i stands for INTERNET

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

 Oracle 10g, 11g

10g and 11g stands for GRID

Starting in 2003 with version 10g and 11g, G signifies “Grid Computing” with the release of Oracle10g 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. 

 Oracle 12c

In the Oracle Database 12c the "c" stands for "Cloud”

In addition to many new features, this new version of the Oracle Database implements a multitenant architecture, which enables the creation of pluggable databases (PDBs) in a multitenant container database (CDB)

 Whether Oracle talks about the connection (“Internet”), the combination of servers (“Grid”), or both (“Cloud”), we always mean: "Place your data on our big, central boxes and you’ll be cool and happy".
