I am trying to create four tables: Company, Contact, Activities, and Opportunities. I want them to relate hierarchically. A Company can have many contacts, contacts can have multiple Activities and Opportunities. But you can't have contacts without a company and you can't have Activities and Opportunities without having a contact. I want all PK's in all tables to link to one another, that you cannot create one without the other. Does anyone know how I can do this in Access 2010?

or
YYMM00000-000000-O0000
CompanyID-ContactID-OpportunityID
Thanks,
Amanda
