I am curious if one can see the internal mechanism of merge join or any other join sql?
For Oracle have a look at this document: Database SQL Tuning Guide - Joins
If you are thinking about how they work, you can look it up here, it's a great representation of it.
If you are thinking about the code behind it, I think you'll have to work for MS to access it ;)

I'm just wondering why you would go to the trouble of specifying relationships between tables.
Is it just for referential integrity?
Ensuring integrity ON THE SERVER has several obvious advantages I can think of:
- it will always be faster than if done by the client (no roundtrips)
- it will protect against developer errors
- you can't always control which client connects to your data
