Oracle is a program which maintains data for us and decides where it should go on the hard drive.In other words Oracle is a relational Database i.e. a collection of Data. The Oracle Database commonly referred to as Oracle RDBMS or simply as Oracle is an object relational database management system (ORDBMS) produced and marketed by Oracle Corporation.

The Oracle RDBMS stores data logically in the form of tablespaces and physically in the form of data files (datafiles). Tablespaces can contain various types of memory segments, such as Data Segments, Index Segments, etc. Segments in turn comprise one or more extents. Extents comprise groups of contiguous data blocks. Data blocks form the basic units of data storage.

There is also a partitioning feature available on newer versions of the database, which allows tables to be partitioned based on different set of keys. Specific partitions can then be easily added or dropped to help manage large data sets. Oracle database management tracks its computer data storage with the help of information stored in the system tablespace. The system tablespace contains the data dictionary and often indexes and clusters. A data dictionary consists of a special collection of tables that contains information about all user objects in the database.

The database product provided by Oracle is the world leader. It is provided as a back-end information centre to a great number of websites owned by large corporations. It has its own language, PL/SQL. It provides XML support and has supporting tools for developers, such as Forms, Reports, and recently has become the global leader in CRM technologies, having taken over Siebel Systems in 2006.

Oracle technology includes Application Server, which serves all the various applications available in the Oracle suite of products. This has high availability built into its server functionality so that the applications are reliable in their operation.
