Hi, I have an address table, and employee and customer tables. I am thinking of adding an address_owner field to the address table and use it as a foreign key referencing both the customer_no and the employee_no number. I have just done that on mysql, but I do not feel that confident about it - is this acceptable? what are the pros and cons? Am I on the right track? and how else can I handle this? (I understand I can have link tables tables to keep the links but that looks like too much and unnecessary?) Best Regards
