    - In a homogenous distributed database system, each database is an Oracle database.

    - In a heterogeneous distributed database system, at least one of the databases is a non-Oracle database.

    - Distributed databases use a client/server architecture to process information requests.

    - Client/Server Database Architecture
    - A database server is the Oracle software managing a database, and a client is an application that requests information from a server.
    - Each computer in a network is a node that can host one or more databases.
    - Each node in a distributed database system can act as a client, a server, or both, depending on the situation.
    - A client can connect directly or indirectly to a database server.
    - A direct connection occurs when a client connects to a server and accesses information from a database contained on that server.
    - In contrast, an indirect connection occurs when a client connects to a server and then accesses information contained in a database on a different server.
