The much anticipated 12c version of Database was made available for download on 25th June 2013 on OTN here. The most important new feature in this latest release is the Pluggable Databases.
This will give a big boost and strong hold to Oracle in the Cloud technology and rightly ‘c’ in ’12c’ stands for cloud.
I have tried to depict this new feature of Pluggable Database in 12c using below image.
Hope my analogy to explain all important new feature of Pluggable Database is useful.to all my readers.
