Write a query to display (product_class_desc, product_id, product_desc, product_quantity_avail ) and Show inventory status of products as below as per their available quantity: a. For Electronics and Computer categories, if available quantity is <= 10, show 'Low stock', 11 <= qty <= 30, show 'In stock', >= 31, show 'Enough stock' b. For Stationery and Clothes categories, if qty <= 20, show 'Low stock', 21 <= qty <= 80, show 'In stock', >= 81, show 'Enough stock' c. Rest of the categories, if qty <= 15 – 'Low Stock', 16 <= qty <= 50 – 'In Stock', >= 51 – 'Enough stock' For all categories, if available quantity is 0, show 'Out of stock'. Hint: Use case statement. (60 ROWS) [NOTE: TABLES TO BE USED – product, product_class]

Order Management Schema Details

 

This document captures the scenario of simple order management functionality of an online retail store. 

Typical purchase scenario: A customer places an order for N products specifying quantity for each line item of the order. Every product belongs to a product class (or category).  All products ordered in one order, are shipped to customer’s address (in India or outside) by a shipper in one shipment. Order can be paid using either Cash, Credit Card or Net Banking. 

There can be customers who may not have placed any order. Few customers would have cancelled their orders (As a whole order, no cancellation of individual item allowed). Few orders may be ‘In process’ status. There can also be products that were never purchased.

Shippers use optimum sized cartons (boxes) to ship an order, based on the total volume of all products and their quantities. Dimensions of each product (L, W, H) is also stored in the database. To keep it simple, all products of an order are put in one single appropriately sized carton for shipping.

                                     

                                             Project- (SQLite & MYSQL)

 

You are hired by a chain of online retail stores “Reliant retail limited”. They provided you with “orders” database and seek answers to the following queries as the results from these queries will help the company in making data driven decisions that will impact the overall growth of the online retail store.

1st part- Q1-Q6 comes under SQLite and queries should be executed in DB Browser. (Database  - Orders.db)

2^nd part- Q7-Q10 comes under MYSQL and the queries should be executed in MYSQL. (SQL Script        -orders.sql)

All Questions carry 8 marks. Total Marks (8 x 10) = 80

2. If the category is 2051, increase the price by 500
3. If the category is 2052, increase the price by 600.

2. For Stationery and Clothes categories, if qty <= 20, show 'Low stock', 21 <= qty <=

80, show 'In stock', >= 81, show 'Enough stock'

3. Rest of the categories, if qty <= 15 – 'Low Stock', 16 <= qty <= 50 – 'In Stock', >= 51 –
