A distributed database (DDB) is a collection of multiple logically related database distributed over a computer network, and a distributed database management system as a software system that manages a distributed database while making the support, database self-containment, and schema evolution. An important goal in designing a distributed DBMS is to make it fault tolerant (i.e., to avoid a single one node failure taking down the entire system). �����r�8���;� The concepts themselves are defined and then the different systems are described. These can be stored in the form of Why distributed database, interesting facts about distributed database Advanced Database Management System - Tutorials and Notes: Distributed Database - Why?
