that looks right. I do not use relationships in my databases because it 'locks' you into using the defined relationships rather than letting you free-form things but yes, you're correct in your linking system. though usually it goes the other way where you'd link FROM your table tblTransactions and you'd have an alias for each one of your links to tblCompanies (in other words you'd have 3 copies of your tblCompanies in your relationship diagram) but I think the way you've done it is correct.
