Answer 1

DMRC

Answer 2

In the context of SQL Server technology, DMRC typically stands for Distributed Management and Replication Controller. This feature in SQL Server enables the management and coordination of distributed databases as well as the replication of data between these distributed instances.

DMRC helps in maintaining consistency across different database instances in a distributed environment. It facilitates tasks such as coordinating schema changes, ensuring data synchronization, and managing replication configurations efficiently.

Here is a simple example of using DMRC to manage replication in SQL Server:

-- Create a publication
EXEC sp_addpublication @publication = 'MyPublication';

-- Add articles to the publication
EXEC sp_addarticle @publication = 'MyPublication', @article = 'MyTable', @source_object = 'dbo.MyTable', @type = 'table';

-- Create a new snapshot for the publication
EXEC sp_addpublication_snapshot @publication = 'MyPublication';

-- Create a subscription to subscribe to the publication
EXEC sp_addsubscription @publication = 'MyPublication', @subscriber = 'SubscriberServer', @destination_db = 'MyDestinationDB';

This code snippet demonstrates the basic steps involved in setting up a publication, adding articles to it, creating a snapshot, and then adding a subscription to subscribe to this publication. DMRC plays a crucial role in managing these replication tasks effectively.

By utilizing DMRC functionalities in SQL Server, organizations can ensure smooth operations and reliable data replication across their distributed database environment.
