G signifies "Grid Computing"... With the release of Oracle 10g in 2003, Oracle changed the suffix in their previous release version; from 9i to 10g... 'I' stands for Internet...this was done as a marketing effort in order to show Oracle's move towards Grid Computing... Purely a marketing strategy...
