E-Commerce-Rule-Engine
Rule Engine implemented in Python. The project came second in Zivame Hacakathon-2014. The algorithm was designed and implemented in the 24 hour coding session.

Problem Statements
Problem A Responsive Mobile Site/App
Build A responsive optimized mobile shoe store. Build a category page, product page and a cart page.
Product Attributes: ● Main image ● Other images ● Categories (can be many) ● Price (MRP) ● Special Price (discounted price) ● Description ● Size (multiple) ● Color (can be multiple per size) ● Inventory (has to be per color, which is in turn per size)
Category Attribute: ● Name
Technology Node.js (preferred) / PHP / Python / Java
Database Use a NoSQL database like MongoDB
Judging Criteria Choice of Architecture NoSQL Schema Application Performance
Problem B Rule Engine
Build A Rule Engine from scratch (do not use any available open source rule engine). We are expecting a User Interface for entering the rules.
Database schema The sample database schema is given below
table_category category_id int(11) category_name varchar(100)
table_product product_id int(11) product_name varchar(100) product_price decimal(8,2) product_special_price decimal(8,2)
table_product_category f_product_id int(11) f_category_id int(11)
Input The input to the rule engine is a set of products with its categories and special price.
The rule engine needs a set of conditions and a set of actions listed below.
Conditions Cart total Category id
Exclusions: Category id
Actions Free Shipping % Discount Flat Discount Free Product
The conditions and exclusions can be grouped via brackets.
Samples Input: [ { "product": { "id": "", "category_id": [ "" ], "price": "" } }, { "product": { "id": "", "category_id": [ "" ], "price": "" } } ]
Rule
IF
“cart total” [>/<] “predefined value”
AND/OR
“category is” [is] “predefined value”
AND/OR
“category id” [not] “predefined value”
THEN
[free shipping || %discount = “predefined value” || discount = “flat
discount value” || free product = “product id”]
Example rules:
Rule 1
IF {price > 1000 AND category_id in “200,201,200”} THEN {%discount = “20”}
Rule 2
IF {cart_total > 5000} OR {price > 3000 AND category_id NOT IN “200,201,202”} THEN {discount = “1000”}
Judging Criteria Correctness Choice of algorithm(s)
