The concept of replication Replication, as an important and powerful technology, provides strong support for the storage and processing of distributed data. Microsoft SQL Server can generate a number of According to the copy, and can distribute the copy of these data to different places, automatic data synchronization

The execution of the set-azurermsqldatabasesecondary command is also divided into two stages: First, it is the synchronous mode of switching the data copy operation to complete all data copying from the database (to ensure that the contents of the master and slave libraries are th

Each ER node may be a single server or a cluster of servers, as described later in this article. All of these interconnected nodes are collectively referred to as an ER field (domain). The domain does not define which data is transferred, but only the path or route that is passed when the data is transmitted. Next, determine which data you wa

Replication is the most powerful and complex component in SQL Server, so it is unavoidable to replicate errors in specific applications. But, thankfully, SQL Server provides replication management tools-
