can someone check my relationships

Can someone check my relationship and suggest if they are correct. Please do not comment on the design just the relationship.

can't tell, not without a clear indication of the FKs

presumably the PKs are the underlined ones? why are some columns underlined and others bolded?

I believe the ones in bold are fk's? Looks ok (disclaimer). What is your db defined as? A property db? What does the branch table respresent? How would you summarise this database?

underline = pk
bold = fk

this is a real estate database. the branch represents a office

can you check whether the 1.* and 1.1 relationships are correct?

Only one viewing per client? No key for branch or registration?
