SQL Database Concepts Question:

When we want to query on remote database server along with the local database server then we can add the remote SQL server to local SQL server in a same group using the concept called Linked Server.
We can query on both servers using T-SQL.
We can use stored Procedure sp_addlinkedserver, sp_addlinkedsrvlogin to add new Linked Server.
By using Linked Server we can SQL statement in clean and easy way to retrieve, join and combine remote data with local data.
