Data synchronization involves the primary database sending transaction log records to the secondary database. Structure Query language (SQL) usually going to scale up vertically by enhancing the hardware investment, so it is most time consuming as well as pricey. If an availability group currently possesses an availability group listener and one or more readable secondary replicas, SQL Server can route read-intent connection requests to one of them (read-only routing). As well as, it can be also used into several applications as per users requirements. So, every update will be expensively and resource consuming. In contrast to database mirroring, there's no witness role in Always On availability groups. The availability mode is a property of each availability replica.

Ted Codd of IBM is called the father of relational database because he explored the relational model for a databases; then further it was appeared the Structured Query Language, in 1974. Logs are applied to mirror database based on a schedule. Each availability replica of a given availability group must reside on a different node of the same WSFC. A read scale availability group provides replicas for read-only workloads but not high availability. There you have it! And best of all, this solution works with SQL 2005/2008/2008R2/2012 Standard Edition as well as Enterprise Edition, so the cost saving alone on SQL Server licensing can more than pay for the solution (more on costs saving in my next post). A solution such as NSI's double take could be considered for high availability also, however I prefer to use it for disaster recovery for non-SAN based systems. Therefore it is most trustable and efficient language for making the database communication. Receiving a ping from the other replica during the timeout period indicates that the connection is still open, and that the server instances are communicating. Always On availability groups supports active secondary replicas. How Do You Write a SELECT Statement in SQL?
