Meaning of i and g in Oracle 9i & 10g

The i in oracle 8i and 9i stands for INTERNET and the g in 10g and 11g stands for GRID

bcz from 10g onwards oracle supports grid architecture.

The "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.
