OLAP, Oracle Label Security, and Oracle Data Mining.

638 Oracle Database 11g DBA Handbook
Standard Edition One This edition provides the same features of Standard Edition, except
for Real Application Clusters, and is limited to a single server with a maximum of two CPUs.
Personal Edition Allows for the development of applications that will run on either the
Standard or Enterprise Edition. This edition cannot be used in a production environment.
Express Edition Oracle Database Express Edition is an entry-level edition of Oracle
database that is simple to install and manage, and is free to develop, deploy, and
distribute with your applications. It supports use of one CPU (or a dual-core CPU) and
is only restricted to 1GB of RAM and 4GB of disk space for user data. Using the Express
Edition makes it easy, if not trivial, to upgrade Oracle Database to another edition.
As of Oracle 10g, licensing for the Oracle Database is only by named user or CPU, and there
is no longer a concurrent user licensing option.
