                                                                                Task 3:

1. select * from customers order by city ASC;
2.alter table products add prod_ char (20);

3.
SELECT COUNT(product_id),NAME,collor,Brand,cost,payment
FROM Orders
GROUP BY product_id
HAVING COUNT(product_id) > 1;
4.
SELECT * FROM orders
WHERE NAME LIKE 'k%' AND NAME LIKE'%d' ;
SELECT COUNT(product_id),NAME,collor,Brand,cost,payment
FROM Orders GROUP BY product_id HAVING product_id> 1;
5.
SELECT COUNT(product_id),NAME,collor,Brand,cost,payment
FROM Orders GROUP BY product_id HAVING cost>14000 AND product_id>1;

6. First we have created Entity Realtion (ER) diagram and given realtions to it as per the input given by the .

In SQLyog we have created database and then created the required tables like Register, customer, seller, discounts, products,administartion,categories_1, categories_2, orders, wishtlist, reviews and cart.

For tables which already created as per our code requirement for few attributes we have considered the primary key and foreign key where ever it is required.
After that we have inserted the values for all the tables as per the fields input.
And finally we have write down the queries for given inputs.
