It's difficult to build a good data model from the limited amount of
information provided, but assuming that is _all_ the information you need to
store, the quickest answer (not necessarily the best), would be to store the
data in two tables.
Order Table
-----------
OrderID
Quantity
CardID
OrderInfo Table
---------------
OrderID (which is also a FK to the Order Table)
ProofRequired
CustomerComments
ReorderNumber
DealerPONumber
DealerNote
OperatorInitial
OperatorNote
This would potentially save space, but makes your model more complicated.
If you really want to model it properly (i.e., normalized), you should
consider whether you are looking at a supertype/subtype situation, in which
you might end up with many tables. For example:
Order Table
-----------
OrderID
Quantity
CardID
OrderInfo Table
---------------
OrderID (which is also a FK to the Order Table)
ProofRequired
CustomerComments
ReorderNumber
OrderDealer Table
-----------------
OrderID (which is also a FK to the Order Table)
DealerPONumber
DealerNote
OrderOperator Table
-------------------
OrderID (which is also a FK to the Order Table)
OperatorInitial
OperatorNote
You would do this if there was a logical grouping of optional attributes.
For example, if it were often the case that you needed to store
DealerPONumber and DealerNote, but _not_ OperatorInitial and OperatorNote.
Of course, you also have the option of storing everything in one big table.
This would depend on your storage and performance considerations.
Hope this is what you were looking for,
Bob

Subject: Slightly OT -- Database Question
Hello,
I have a question regarding database design. I have an application that
will take information for orders. This application will have certain
required fields and certain optional fields. I am wondering what the best
table structure breakdown will work best for this application, as you will
see there are many more optional fields than required fields:
Required Information:
OrderID
Quantity
CardID
Optional fields:
RushDelivery
ProofRequired
CustomerComments
ReorderNumber
DealerPONumber
DealerNote
OperatorInitial
OperatorNote
Thank you for any help/suggestions!
Sincerely,
Craig
