A distributed database is a database that consists of two or more files located in different sites either on the same network or on entirely different networks.
In general, distributed databases include the following features: 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.
The DDBMS synchronizes all the data periodically and ensures that data updates and deletes performed at one location will be automatically reflected in the data stored elsewhere.
