I have a Customer table with CustomerID as PK, an Interest table with InterestID as PK and a Join Table CustomerInterests with a CPK made up of CustomerID & InterestID to handle the many to many relationship between the customers & interest groups. Here's what I need:
1) A neat overview of customers that share a particular interest, and customers that don't.
2) I would like to be able to sort or filter these customers by features (eg last name, customer's employer, etc.).
3) I need to be able to add/remove a customer from the interest list, ie. the method should directly impact the Join Table records. If possible, I'd prefer a non VBA solution.
4)A plus, but not a necessity, would be a solution that displays all this information for several interests at the same time, not just one.
I'm not that familiar with access, but my intial thoughts were this:In a query, I'd have a row for each customer, and a column for each interest, and have an expression resulting in "true/false" or an "x" if the CustomerID&InterestID combination exists in the the Join Table. And then find some way to add/delete a Join Table record when a field is manually changed from True to False or viceversa.
I have no idea how to go about it. I use Access 2003.
