Distributed Databases Overview
A distributed database is a network of databases managed by multiple
database servers that are used together. They are not usually seen as a
single logical database. The data of all databases in the distributed
database can be simultaneously accessed and modified. The primary
benefit of a distributed database is that the data of physically
separate databases can be logically combined and potentially made
accessible to all users on a network.
Each computer that manages a database in the distributed database is called a node. The database to which a user is directly connected is called the local database. Any additional databases accessed by this user are called remote databases. When a local database accesses a remote database for information, the local database is a client of the remote server. This is an example of client/server architecture.
A database link describes a path from one database to another. Database links are implicitly used when a reference is made to a global object name in a distributed database.
While a distributed database enables increased access to a large amount
of data across a network, it must also hide the location of the data
and the complexity of accessing it across the network. The distributed
database management system must also preserve the advantages of
administrating each local database as though it were not distributed.
