what is oracle database

A relational database management system (DBMS) from Oracle, which runs on more than 80 platforms. The Oracle database, the current version of which is Oracle11i, is Oracle's flagship product. It was introduced in the late 1970s and was the first database product to run on a variety of platforms from micro to mainframe.

Version 8 (Oracle8) added object-oriented extensions, and Version 8i (Oracle8i) added Internet enhancements in 1999, including support for XML and Java.

 A JVM (Java interpreter) is built into the DBMS so that triggers and stored procedures can be written and executed in Java rather than PL/SQL. It enables Internet developers to write applications and database procedures in the same language. In addition, the JVM can also execute Enterprise JavaBeans (EJBs), turning the DBMS into an application server.
