Clark > Supplier Systems Corporation I beg to differ. It would be a many to many if several customers were related to the same issue. If each customer can have one or more issues, but no issue can 'belong' to more than one customer then its 1 to many and you can put the customer ID in the issues table. If several customers can have the same issue (row) then you will need an intermediate table which has two columns: customerID and issueID. --- William R.
