2015-08 – What’s new in 12c DBMS_COMPRESSION

DBMS_COMPRESSION is a package used to manage the Oracle Database table compression feature. This feature lets you compresses data by eliminating duplicate values in disk pages. As database grows in size, table compression saves resources, not only disk storage but also reduces memory use in the buffer cache. First introduced in 11g R2, this package has been evolving, and some very useful enhancements were introduced now in 12c release.
