Abstract:
A distributed database is a database with
its data elements are stored at several sites of a
computer network. Certain data items may be
redundantly stored at more than one site for
reliability reasons. A replicated database is a
distributed database in which multiple copies of
the same data items are stored at different
sites.Replication is the one of the good way to
increase the performance of database system by
maintaining different servers. Database
replication is used to provide high availability and
performance for accessing data. In order to
distribute database load to different database
servers rather having a single mainframe server,
replicate data. In this way, work load on single
server can be decreased.In this system, the merge
replication technique of data replication is used to
ensure consistency and ease of access from any
remote location. The user can perform any type of
banking operation (Deposit, Withdraw, Transfer)
at their convenient bank and no need to concern to
go their account registered bank. Although, the
operations are performed at the branch of desire
location, the system replicates the committed
processes to all branch via the merge server for
the future time of accessing to be a consistence
state data.
