The rule for distributed databases that states that the performance of functions such as adding sites, changing versions of DBMSs, creating backups, and modifying hardware should not require planned shutdowns of the entire distributed database is known as continuous operation. This means that the distributed database system should be able to remain operational and accessible to users even during maintenance or upgrades on individual sites or components. Local autonomy refers to the ability of individual sites to control their own data and processing, location transparency refers to the ability of users to access data without knowledge of its physical location, and fragmentation transparency refers to the ability of applications to access data that is partitioned or distributed across different sites as if it were stored in a single location.
