Database Replication Software
allows to synchronize copies of database at multiple
database servers and also enables to simultaneous
reading and writing of data by multiple users. If
one of servers has crashed, those users who links
to that server can be automatically redirected to
the another server. This feature allows to increase
reliability of the system practically up to 100% and
allows database servers to be physically located far
away from each other.
Database Replication Software
is typically used for:
-
Balancing and distributing of server
load
-
Synchronizing multiple branches of
the company
-
Warm backuping of servers
-
Publishing updates
-
Keeping mobile computer users Up-To-Date
Database Replication Software
allows to distribute and synchronize structured, relational
data or partial sets of a data between any servers.
Database Replication Software can be easily integrated
or embedded into any projected or existing application
and will provide the very effective way to keep critical
data fully synchronized across a distributed company.
Database Replication Software
allows end programs to work faster, more reliably,
because those programs can use local databases, which
are always up-to-date. Process of the synchronization
can be scheduled or can be performed automatically
during period of connectivity to guarantee that end
users always have access to the last critical information.
Database Replication
very differs from from File Replication,
which simply copies files from one server to another.
Database replication software log selected database
transactions and store them into a set of internal
replication-management tables. The database replication
software then periodically checks these tables for
new or changed records and moves such records from
the source to the target database while guaranteeing
integrity and consistency of the data.
Database Replication Software
can resolve most of the problems inherent in distributed
data systems. Database replication software can also
provide additional reliability to your disaster-recovery
plans by duplicating the data from a local database
server to a servers which are on big distance.If the
primary server has a crash, your applications will
be switched to the replicated copy of the database
and continue works.
