Designing Factors of Distributed Database System: A Review

A distributed database is a database in which not all storage devices are attached to a common processor.[1] The storage devices are stored in multiple computers, situated in the identical physical locality or may be isolated over a network of interconnected computers. Contrasting parallel systems, in which the processors are tightly coupled and constitute a single database system, a distributed database system consists of loosely coupled locations that share no physical mechanisms. This paper addresses various challenges in designing a distributed database. This paper also addresses designing factors in distributed database like replication, duplication, architecture, fragmentation, security and database integrity across multiple database and review the previous work done recently.
