    - The terms distributed database and distributed processing are closely related, yet have distinct meanings.

    - There definitions are as follows:

    - Distributed database - A set of databases in a distributed system that can appear to applications as a single data source.

    - Distributed processing - The operations that occurs when an application distributes its tasks among different computers in a network.
    - For example, a database application typically distributes front-end presentation tasks to client computers and allows a back-end database server to manage shared access to a database.
    - Consequently, a distributed database application processing system is more commonly referred to as a client/server database application system.

    - Oracle distributed database systems employ a distributed processing architecture.

    - For example, an Oracle database server acts as a client when it requests data that another Oracle database server manages.
