Oracle Database is the world’s most popular database. Available on cloud and on-premise platforms, Oracle Database 19c is the most recent long term release, with an extended support window. Oracle Database 21c is the latest innovation release, initially available on Oracle cloud through Autonomous Database Free Tier and Database Cloud Service.
An Oracle Database consists of at least one database instance and one database. The database instance handles memory and processes. The multitenant container database consists of physical files called data files. An Oracle Database also uses several database system files during its operation.
A single-instance database architecture consists of one database instance and one database. A one-to-one relationship exists between the database and the database instance. Multiple single-instance databases can be installed on the same server machine. There are separate database instances for each database. This configuration is useful to run different versions of Oracle Database on the same machine.
