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?

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
