10g is Oracle's grid computing product group including (among other things) a database management system (DBMS) and an
application server. In addition to supporting grid computing features such as resource sharing and automatic load balancing,
10g products automate many database management tasks. The Real Application Cluster (RAC) component makes it possible to install
a database over multiple servers.
10g follows Oracle's 9i platform. Oracle says that the g (instead of the expected i) in the name symbolizes the company's
commitment to the grid model. However, according to some reports, many early adopters are deploying 10g solely for its
automation features and have no immediate plans of implementing a grid environment.
Definition of: Oracle database
A relational database management system (DBMS) from Oracle, which runs on more than 80 platforms. Introduced in the late 1970s,
Oracle was the first database product to run on a variety of platforms from micro to mainframe. The Oracle database is Oracle's
flagship product, and version 11g was introduced in 2007.
Oracle 11g features include built-in testing for changes, the capability of viewing tables back in time, superior compression of all
types of data and enhanced disaster recovery functions.
The "i" and "g" Versions
Starting in 1999 with Version 8i, Oracle added the "i" to the version name to reflect support for the Internet with its built-in Java Virtual Machine
(JVM). Oracle 9i added more support for XML in 2001. In 2003, Oracle 10g was introduced with emphasis on the "g" for grid computing,
which enables clusters of low-cost, industry standard servers to be treated as a single unit.
