| Introduction 1 Collecting information

Currently, the demand for nutritional supplements is increasing, causing the number of customers looking for milk to increase So, our team collected data on the business performance of a dairy store

We collect information through interview method

Step 1: We prepare questions about business performance to interview sellers These questions relate to:

+/ List of buyers and personal information of some customers, list of milk, order details and ingredients therein (With a commitment not to use for bad purposes)

+/ See product price list

Step 2: We go to this store and ask the salesperson there During the interview process, our group had a member write down key information about the store's operations At the same time, we also used a tape recorder to record the entire interview process and a camera to take some necessary photos

Step 3: We screen essential ideas and start working on our project Overall, the scope of this project involves sales activities at the dairy store

2 Business narratives

First, when a customer comes to buy for the first time, the payment counter will take the customer's information including: Name, Date of Birth, Gender, Phone Number, Email and save a unique ID to avoid duplicates Repeat with others Next, the salesperson and customer will discuss with each other about the customer's needs and offer suitable products An order will contain 1 or more different types of milk depending on the buyer's needs

3 Introduction about our project

Analytical tools allow store owners to create customized treatment plans to suit their store The effectiveness of database administration for data management has been recognized by organizations Data management is often critical to management decisions and the success of management decisions is critical to enhancing the business organization.

For your convenience, we have created a Management System on a specifically written Dairy Store Database Design

The main goal of this project is to create a database program for dairy stores This data is useful for any or all of the following reasons:

+/ Want to get off to a good start with your new way of exercising +/ There is a need to buy an existing practice shop

+/ Want to develop and expand the scale of your operations effectively

+/ Second, CHITIETHOADON provides more quantity, price and total compared to HOADON

+/ The third object is SANPHAM, which provides information such as: product code, product name, unit and price

+/ Next is the entity This provides employee code, employee name, store name

+/ Then, the 5th object is KHACHHANG including customer code, customer name and phone number

2.2 Explain the relationship between tables

Additionally, we have 5 entities in the ERD corresponding to 5 tables Among the entities that appear linked is 1 — Many.

1 — Many

To represent a 1-to-many relationship in a database, take the primary key on the "One" side of the relationship, then add that key as one or more additional fields to the table on the "Many" side of the relationship relationship
