Background:
Catamount Pty Ltd is a successful outdoor and camping gear store who now wish to expand
their business by staring an online shopping system to attract more customers since online
shopping is where most buyers shop now.
Definitions
User A potential customer using the online shopping system
Admin Staff of the store who have admin control over the inventory
allowing them to add/remove items from the inventory and update
prices/discounts to items
Item A piece of clothing or camping equipment available for purchase
Discount A deduction from the current price of the item (after any previously
applied discount)
Shopping
Cart
Refers to the current order of a User and comprises the set of items
selected for purchase
Line Item Refers to each individual line in the order and includes details of the
item ordered and quantity ordered
Functional Requirements:
The online shopping system shall address the following requirements:
Maintain an inventory
The inventory stores all items currently sold by the store
Every item in the store has a name, product description and a price.
Items in the store are grouped into categories: clothing and camping gear
Clothing items include shirts, pants, jackets, swimwear, boots and accessories. Items such as
gloves, beanies etc. are grouped under accessories
– All clothing items also have a size and colour.
– Allowable sizes are ‘S’, ‘M’, ‘L’.
– Colour is provide as text e.g. ‘blue’
Camping items include tents, electrical and miscellaneous items. Miscellaneous items
include foldable chairs, buckets etc.
– All camping gear also have dimension and weight
Search inventory
Allow a customer to do a search of all the items currently sold by the store.
The search will display the item name, product description, quantity currently in stock
Allow a customer to do a search by category (e.g., clothing or camping gear) or by subcategory
(e.g., pants, tops, miscellaneous etc.)
Maintain periodic discounts for the various items in the store
The store would like to associate periodic discounts to their items
Currently, discounts can be grouped into individual and group discounts
An individual discount can be a flat discount or a percentage discount.
– A flat discount reduces the current price (after any previously applied discount) by a flat
amount e.g., ‘$20.00 off the current price’
– A percentage discount reduces the current price (after any previously applied discount)
by a percentage ‘20% off the current price’
A group discount is implemented as a ‘BuyXGetOneFree’ strategy, A ‘BuyXGetOneFree’
discount reduces the price of the next same item to $0 for every X Items bought. So for
example, Buy 4 gloves Get One Free means 4 Items are purchased at the current price, and
the 5th of the same Item is free
– Note: A group discount will only apply to items of the same sub-category (e.g. accessories,
pants etc)
Discounts on an item can be chained together, with the most recently added one applied
last
Admin user features
Can add a new item to make it available for purchase
Can remove an Item, effectively making it unavailable for purchase
Can add multiple Discounts to an item
Can remove the top level Discount (most recently added) off an Item
Enable customers to purchase online
A User can choose items from their search and add to a shopping cart
When a User adds an item to their shopping cart, they must specify the quantity of the item
A User can view their shopping cart at any time
The shopping cart must display all the items selected by the user
For each item in the shopping cart,
– the item name, quantity, base-price per unit, the discount applied (if any) and the net
price (base-price less the discount) is displayed
– e.g. Nike-Red-Gloves 5 $5.00 Buy 5 Get 1 Free $20.00
The shopping cart will also display a total price for the entire cart
A User can remove a line item any item from their shopping cart
A User can purchase their cart (and effectively emptying it)
A User can click on check-out any time, to purchase their shopping cart and provide
payment details. (For the purposes of this assignment, the payment processing has been
omitted)
