Problem Description:
Grant, a leading provider of out-sourced online retail solutions, wants you to
design and build a reasoning system that determines pricing and
suggests complementary
products to purchase based on what the customer has placed in their
shopping cart. The
following defines the requirements for the reasoning system:
1. A customer has at most one shopping cart that contains one or more products
(including the quantity of each product) that the customer has selected. Your
system must be able to represent any number of shopping carts.
2. Each product has a title, description, and price. Your system must be able to
represent any number of products.
3. Products are classified into one or more categories. Maximum of five.
4. Each product has associated with it zero or more other products designated as
?cross sells.?
5. Each product has associated with it zero or more other products
designated as ?up
sells.?
6. Each category has zero or more products associated with it designated as
?promotions?.
7. If the customer orders 10 or more of a single product, then they received a 15%
discount on that product.
8. If the customer has five or more distinct products in their shopping basket
(products with quantity n>1 should be counted as 1 product), they can receive a
10% ?quantity discount.?
