Oracle Database software is used to construct and administer the database. The database is made up of physical and logical structures that hold information about the system, users, and controls. The Oracle Database server is the programme that administers the database. The Oracle Database system refers to the software that runs Oracle as well as the actual database.
The data is stored in memory using a database buffer cache for faster access. The redo logs keep track of and store all database changes. A Data Guard guarantees data security and high availability, while a control file records the database’s physical structure.
