Fundamentals of distributed DBMS

A software with a centralized system that handles the distributed database in such a way that all are stored in a single site is known as a database management system (DBMS). The idea of the distributed database system is the centralized database, the data is spread out on a distributed network among the cities each having its computer and data storage facilities. This distributed data management is considered a single logical database.
