Structure of Oracle system
ORACLE database system is a computer system with the function of managing ORACLE database. Each running ORACLE database is associated with an ORACLE instance. ORACLE instance is a software mechanism for accessing and controlling databases.
Every time the database is started on the database server, a memory area called system global area (SGA) is allocated and one or more ORACLE processes are started.
The combination of SGA and ORACLE processes is called an ORACLE database instance. The SGA and processes of the instance are responsible for managing database data and providing services to one or more users of the database.
