This commonality has made it possible for clients to modernize applications moving from language files, to a network database, to a relational database. They can use a mixture of these at the same time in a single program while retaining full recoverability. With all the recovery, clustering, locking, and cache management centralized, applications do not have to deal with those aspects. In OS 2200 locking is generally implicit in the database verbs used. For example, a read-for-update implies setting a certain type of lock and the corresponding update write implies clearing it.
