Oracle’s 12c DBMS {1}

by Eric C
Scheduled for release in 2013, Oracle recently released details regarding the next generation database management system called Oracle 12c. The “c” stands for cloud, as Oracle is focused on making 12c cloud computing friendly. The main selling point of 12c is the ability to virtualize databases in a sever, or hold many instances of different databases on the same system. This featured is dubbed “multi-tenancy” by Oracle’s CEO Larry Ellison and benefits from decreasing hardware costs for major corporations. If a corporation has many database servers running Oracle’s previous DBMS, 12c can consolidate up to 250 separate databases in one server, thus maximizing CPU usage and reducing hardware needed to run the database. Consolidating multiple databases into one server may impact performance as a result of virtualization, however, Oracle would not comment on how they would combat this issue. Ellison only stated that 12c “uses one-sixth as much hardware and runs five times as many databases.” When it comes to security, Oracle stated 12c will feature enhanced security measures to make sure data are isolated and secured from users of other databases. read more...
