Chapter 1: INTRODUCTION

1.1 About the organization

Winmart (formerly Vinmart) is a Vingroup grocery store system that was established on 20 Nov

2014 Vinmart was formally sold to Masan Group on December 3, 2019, and Masan has owned it ever since On 15 January 2022, WinMart and WinMart+ replaced VinMart and VinMart+ as their official names Winmart products include fresh food, household, cosmetic, and pre-processed food,

Instead of only investing in advertising and marketing campaigns, Winmart also invests in customer loyalty programs Customers who shop at Winmart can register to become a member of Win When becoming a member of Win, customers will have exclusive incentives and privileges The WIN Membership program has reached 4 million participants (as of early April 2023) In this report, we have chosen to collect information from Winmart's member customers 1.2 Requirement Specification

1 Method for collecting information

It is not difficult to find information related to Winmart's database system when we have a friend who used to work as a Winmart employee Our team did two types of investigations to find the data we used in this test

Interview:

e We took the time to connect with a friend who worked at Winmart to ask for information related to the supermarket's operating procedures such as warehousing, sales, etc., and information related to employees such as name, age, position Besides, we also asked about the working departments

Experience:

e We have made customers come to Winmart to buy things to get information about invoices,

as well as customer services, and participate in Winmart's membership program,

Research:

e We searched for some more product information on Winmart's website and followed Win's fanpage to update more incentives for both commercial customers and Winmart member customers

2 State the problem

Employee management:

Every supermarket needs an employee management system to store personal information and help organize work and tasks effectively, avoiding confusion

Import goods from suppliers:

When receiving goods from suppliers, warehouse staff are responsible for receiving goods and checking supplier information and the quantity of imported goods If information about goods is missing, employees need to make a list of information about those missing goods In case the

information is complete, the warehouse staff will prepare a receipt, and print and store the receipt

5

Goods:

A supermarket will have a variety of goods, after warehousing and printing receipts, warehouse staff need to classify goods for easy control

Exporting goods from warehouse to counter:

When there is a request to load goods from the warehouse to the counter, the warehouse staff is responsible for checking whether the amount of goods in the warehouse meets the export needs

If the demand is met, the warehouse staff prepares an export ticket On the contrary, the warehouse staff notifies the manager to contact the supplier to place an order

Invoice:

When customers come to buy goods and request payment, the cashier will receive the customer's request and enter the barcode of the goods to proceed with invoicing, calculating money, printing invoices for customers, and storing In case the goods do not have a product code, or the product code is blurred, the cashier needs to report it to the manager for checking

Offers for customers:

A supermarket that wants to stabilize and retain customers should have a loyalty card for customers so that customers can receive incentives when making purchases or receive incentives

on holidays and birthdays

Daily revenue report:

After each shift, the cashier needs to check the money and end the shift In case the actual amount differs from the expected amount, the employee of that shift must report to the manager and supplement If not, the employee prints a shift handover slip The next shift staff checks the money again and opens the shift

Chapter 3: SOME USEFUL REPORTS AND INFORMATION

3.1 Design some useful reports and information for real usage

1 Find products with a total input price greater than 10,000,000 VND

2 Find out which supplier provided what item

3 Calculate the total invoice for each customer

4 Find the customer who buys the most items and calculate that customer's total invoice
