Sometimes, the distributor acts as the publisher and distributor both. It is a storehouse for replication data associated with one or more publishers. It indicates the source database where replication starts and makes data available for other servers configured for use in the replication process. It can have one or more publications where each publisher creates many internal replication stored procedures together to define a data propagation method. It is a database that holds a list of objects that have been identified as replication articles. We can use the following SQL statements to list all articles that are published: If the publication contains one or more subscriptions, the modification requires the re-initialization of all subscriptions independently. If we want to change the property of a publication after it is created, we must generate a new replication snapshot. We can also set the properties at the time of publication creation, but these are simply read-only permissions. This wizard enables us to view the article's attributes and set permissions as needed. We can use the New Publication Wizard to navigate an article. It is possible to create several articles on the same object with some restrictions or limitations. It can be scaled vertically or horizontally by using a filter option. It is the basic unit of replication technique that consists of tables, views, functions, and stored procedures. The following diagram help to understand each entity or component of replication architecture: Article The replication technique in SQL Server is based on the "Publish and Subscribe" concept. It helps in bringing data closer to the user.Each site can put up its own rules and procedures to deal with its own copy of the data. It enables the website to function autonomously.It is simple to maintain and improves the availability in comparison to other databases.It reduces locking conflicts and enhances performance when several users work at separate locations.The following are the main benefits of using replication in SQL Server: It is also used to copy and synchronize data continually, or it can be scheduled to run at pre-defined intervals. It allows using multiple copies of data at different locations simultaneously. This technique distributes the selected part of the database, such as tables and views, unlike other replication techniques where the entire database is distributed. Replication in SQL Server is a technology for copying and distributing data and database objects from one database to another, as well as synchronizing the databases to ensure consistency and integrity of data.
