Oracle Database Version Suffix

Ever wonder what the letter suffix means in the Oracle Database version numbers.

Starting Oracle 8, release 1 Oracle starting adding a single letter suffix to its DB versions

  • Oracle 8i
  • Oracle 9i
  • Oracle 10g
  • Oracle 11g
  • Oracle 12c

The i stood for Internet, or Internet ready this version debuted in the late 90’s and matured in the early 2000’s
g stood for Grid architecture,The current version has c – indicating the move towards a cloud ready database and platform. PDU’s is a major functionality enforcing this move.

More on PDU’s later!!
