    Unanswered: Help with Normalization

    Hi

    Could someone help us with this Normalization, I've created 6 tables, but I think I'm going to have to add an extra one with a dual primary key, but I'm not sure.

    Here's the tablenames, and primary keys:

    tblCompany
    Comapny_ID

    tblReference
    Ref_ID

    tblInvoice
    Invoice_ID

    tblFood&Drink
    Object_ID

    tblAccomodation
    Object_ID

    tblAdditional
    Object_ID

    I think if I add a new table with a dual primary key consisting of Company_ID and Invoice_ID, and add Invoice_ID as Foreign Keys in the tables with Object_ID this should work, am I right?

    What would that new table represent?

    Well If I did a straight link from tblCompany to tblReference, with Ref_ID being the foreign key in tblCompany. It would then give me a many to many relationship wouldn't it?
