A distributed database is a database in which portions of the database are stored in multiple physical locations and processing is distributed among multiple database nodes. Distributed databases can be homogenous or heterogeneous. In a homogenous distributed database system, all the physical locations have the same underlying hardware and run the same operating systems and database applications. In a heterogeneous distributed database, the hardware, operating systems or database applications may be different at each of the locations. Distributed Database: Overview A distributed database is a database distributed between several sites. The reasons for the data distribution may include the inherent distributed nature of the data or performance reasons. In a distributed database the data at each site is not necessarily an independent entity, but can be rather related to the data stored on the other sites.  A distributed database (DDB) is a collection of multiple, logically interrelated databases distributed over a computer network. A distributed database management system (DDBMS) is the software that manages the DDB, and provides an access mechanism that makes this distribution transparent to the user.
