Persistence is an attribute of an object. Whereas a transient CORBA object appears and disappears from memory, an object with persistence retains its existence. Persistence allows an object to be written to a file, and therefore to be stored in a database. For performance purposes, a persistent object can also reside in cache.

The principle that the state or properties of an object is automatically preserved.

In object models, a condition that allows instances of classes to be stored externally, for example in a relational database.

an aspect of object lifetime

Storage of objects and data structures that involves converting complex data structures into a format suitable for file storage. Persistent data is retained by the computer between sessions.

secondary storage of objects

Objects whose state lives beyond the lifetime of the object are known as persistent. The state is usually stored in a database.

The ability of the Object COBOL run-time system to remember the state of all objects in the system between runs. It does this by storing all objects in an indexed file.

Persistence allows the state of an object to be saved to non-volatile storage such as a file or database and later restored even though the original creator of the object no longer exists.

The protocol for transferring the state of a bean between its instance variables and an underlying database.

The concept of keeping an object's data stored in memory or on disk.
