ABSTRACT
This chapter aims to educate customers about the new features of Oracle 12c. The main feature offered by Oracle is its multitenant architecture. This feature makes it easy for managing many databases through one database. The heat map feature helps the database administrator (DBA) to manage storage and CPU usage. Therefore, Oracle DBA can arrange data which is hot or cold. The most popular feature is in-memory, and Oracle’s in-memory is 40 times faster than that of the others. Identity column is another feature added based on expectations of Oracle developers. Multiple indexes weren’t supported earlier but were later supported through Oracle 12c.
