"Server" vs "Data Source" in connection string

Question

I'm new to SqlServer, right now I have SqlLocalDb installed to work locally. Good, but I can see two connection strings typically and both works:

Data Source=(localdb)\v11.0;Integrated Security=true;

and

Server=(localdb)\v11.0;Integrated Security=true;

What exact difference is there between the two?

Answer 1

For the full list of all of the connection string keywords, including those that are entirely synonymous, please refer to the SqlConnection.ConnectionString documentation:

These are all entirely equivalent:

• Data Source
• Server
• Address
• Addr
• Network Address

Answer 2

... There is no difference between Server and Data Source as they represent the same thing for SQL Server : the full name of the SQL Server instance with the syntax "MyComputerName\MyShortInstanceName" , potentially including the port used by the SQL Server instance to communicate.
