What is meaning of i, g and c in Oracle Database Version

Oracle DBAs and Developers .. ever wondered the meaning of i, g and c in Oracle Database Releases version .So I try to explain you in simple language.

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)

So I hope you all now know what is the meaning of “i”,”c” and “g” in Oracle Database.
