I realize there is a bit more to MV database design then just parent-child relationships. The lack of constraints is both a curse and a blessing in the MV world. However, I don't accept that you wouldn't want a product category file that holds all the product information in MV fields or order and invoice data as MV fields in a customer file. A single read sounds intriguing in a web app?!?!?!? 'We act as though comfort and luxury were the chief requirements of life, when all that we need to make us happy is something to be enthusiastic about.'

There is obviously a little bit more to mv database design than just parent-child relationships. On 22/12/2010 19:49, Shawn Hayes wrote: > Why would it need to be application specific?
