Database Replication Software

Database Replication Software (D.R.S.) allows to synchronize copies of SQL 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.

SQL Database Replication Software is typically used for:

  • • Balancing and distributing of SQL server load

  • • Synchronizing multiple branches of the company

  • • Warm backuping of SQL servers

  • • Publishing updates

  • • Keeping mobile computer users Up-To-Date

D.R.S. 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.

D.R.S. 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.

D.R.S. 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 sql database and continue works.
