You could add an ID to the Product Option table and include that in the
mapping table (ProductOutlet):
ProductOutlet:
FK to Product
FK to Outlet
FK to ProductOption
price (overrides default price)
quantity
If you do it this way, I'm not sure you need the FK to product in the
ProductOutlet table since the FK to ProductOption would point to the
product. You could keep it for convenience.

yes. Really the main differences between options at the outlet level
is going to be inventory. So amazon could have 5 size 11 air jordan's
and ebay could have 10 size 11 air jordan's.

Are we to assume that options can be different between Product Outlets?

I thought I would see if any of you DBA's out there have any advice.
I'm building an inventory system that deals with inventory tracking,
and also with where inventory is being sold (outlets). I'm having a
bit of a problem with dealing with outlet over rides. For example, I
have a pair of shoes and the shoes are available in different sizes.
I'm selling these shoes on amazon.com and ebay.com. I want my price
to be different for amazon than with ebay. I'm trying to build the
tables that deal with the outlet differences. Let me put up a
simplified version of the current database:
Product:
name
sku
price
manufacturer
weight
box-dimensions
type (can be master or normal. If master then see options table)
...etc...
Product Option:
FK to Product
sku
desc
value
Now I have the Outlet:
Outlet:
name
url
...etc...
ProductOutlet:
FK to Product
FK to Outlet
price (overrides default price)
quantity
Now here comes the part that I'm confused about. How should I deal
with the Product options? I've thought of a few ways to deal with
them, but none seem very good. The ProductOutlet table is a many to
many relationship. It seems odd to me to add an option table that
refers to a many to many lookup table.
ProductOptionOutlet?
FK to ProductOutlet (navigating back to product gets tedious, I can
add more FK's)
FK to ProductOption
quantity
Does anyone have any suggestions for how I could deal with this? I'm
really not even certain if I should keep the way that I'm dealing with
products and their options.
Thanks,
James Lance
