I've been handed an Access Database to assess the possibility of moving to SQL and to put a new front end on to it.

I've opened the database. My exposure/experience to access is limited. 

The first thing I've done is to click the relationship button and add all the tables, there are no relationships defined. Crying Sad

Is it possible that these could be done in the code? (I've had a quick look, doesn't appear to be)  If so would it be exposed by the relationships view?

Thanks in advance.
