In a distributed data processing system, a database can be centralized or distributed. Explain each
When the database is centralized, the entire database is stored at a central site which processes requests from users at remote locations. The central site performs the functions of a file manager that services the data needs of the remote users.
Distributed databases can be partitioned replicated. The partitioned approach splits the central database into segments or partitions that are distributed to their primary users. When the database is partitioned, users have more control over data stored at local sites, transaction processing time is improved, and the potential of data loss is reduced. When the database is replicated, the entire database is stored at multiple locations. Replicated databases are effective where there is a high degree of data sharing but no primary user. Data traffic between sites is reduced considerably. The primary justification for a replicated database is to support read-only queries.
