The name Oracle refers to either:
Oracle database, the famous database management system (DBMS) that is widely used for business applications, and runs on most mainframe, micro, and personal computers or Oracle Corporation, the name of the company that sells the Oracle Database Management System. Oracle Database is the first database designed for enterprise grid computing, the most flexible and cost effective way to manage information and applications.
An Oracle database is a collection of data treated as a unit. The purpose of a database is to store and retrieve related information. A database server is the key to solving the problems of information management. A database server also prevents unauthorized access and provides efficient solutions for failure recovery.
The database has logical structures and physical structures. Because the physical and logical structures are separate, the physical storage of data can be managed without affecting the access to logical storage structures.
