database replication tools

With modern organizations creating large volumes of data as part of their routine operations, there is a growing need for data integration to deal with complex data center environments with multiple different systems. This data has to be understood and analyzed in the aggregate and not in isolation. Data integration at its core is the technique and technology for providing a unified and consistent view of data across an organization. What can data integration software and tools do for a business enterprise? •It can process unstructured data from social media, web pages, email. •Specific software can carry out syntactic and semantic checks to ensure that the data is following business rules and policies. •Cutting-edge data integration tools can process data from a wide range of sources like enterprise applications, mainframes, proprietary databases, spreadsheets, and more. •Remove duplication and incorrectly or improperly formatted data and provides support for metadata All these go

Replication is a technology for copying and distributing data and database objects from one database to another. The databases are then uniformly synchronized to ensure consistency. There are several ways to distribute data to different locations and mobile or remote users - over wireless and dial-up connections, local and wide area networks, and the Internet. There are mainly three types of SQL server replication tools. Snapshot Replication – A “snapshot” of all data on one server is taken and the data is moved to another server or another database in the same server. After the first synchronization snapshot, replication refreshes the data in published tables over fixed pre-programmed periods. While this technology is the easiest to set up and maintain, all data has to be copied every time a table is refreshed. Transactional Replication- It copies data from the publisher to the subscriber/s once and then transports the transactions to the subscriber/s as and when they take place
