======================================================================

What is TsqlTools-SQLcompare? 

TsqlTools-SQLcompare is a tsqlscript that will help to compare Databases, 
Tables, Objects, Indexices between two servers without any tools.

======================================================================
How to Start?

Use a centalized server  and create LinkedServers from the centralized server.
Or Create LinkedServer on SourceDB server then run this query on SourceDB server.
