CHAPTER I: OVERVIEW OF THE TOPIC

I. WHY CHOOSING THIS SUBJECT?
In the past, most of us would buy food mainly from wholesale markets, buying
agents in big centers or in markets and department stores. Today, the development of the
digital economy has changed the business perception of the whole society. It can be seen
that all products and services can be introduced and "sold" on the Internet. Moreover,
customers increasingly need to know information about the origin and origin of
agricultural products that ensure quality and safety for health or not? Therefore, in
addition to improving food quality, brand communication, and packaging improvement to
affirm quality reputation, managers need a more effective communication channel and
app design is the ultimate solution. selected best. Owning a sales app will help businesses
attract more potential customers through the internet. According to the latest statistics,
Vietnam currently has about 41 million internet users, accounting for about 45% of the
country's population, most of which are young people with high shopping needs.
Moreover, nowadays, the online trend is developing day by day and is buying by many

users. About one third of the population uses the internet to search and look up
information about services and products. Therefore, when you have a sales app, your
business has attracted a number of customers on the internet. Without the app, you would
have lost an opportunity to sell and give that opportunity to competitors.

II. PROJECT OBJECTIVES
Promote sales activities anytime, anywhere. Customers will not have to come
directly to the store or purchase according to the store's operating hours but can buy at
any time. This helps to maximize sales opportunities, boost sales and facilitate
customers to shop, making them more satisfied.
Reduce business costs. Having a sales app will help save a lot of costs for store
rental, warehouse and human resource costs. In addition, having a sales app also
makes the payment of customers convenient and easier. Customers can pay via ATM
cards, through electronic payment methods.

Having a separate sales app for the business will also help improve the
reputation and brand value of the business. The face of a business on the internet is the
app and the colors, features and information on the app will fully reflect the image of
the business with the customer, contributing to affirm the company's brand value in
the hearts of the public.
III. EXPECTED RESULTS
Design database for the application of ordering products through the app.
Build management and business processes for the app model.
IV. PRACTICAL SIGNIFICANCE
1. For users
When the software was built, it became easier for the housewives to shop and
cook. Specifically, through each form of software including customer management,

food import and export management (export here means providing food to customers).
Thanks to that, the manager can comprehensively monitor the data and use it properly,
thereby helping the usage process and supporting decision making in the best way.
2. For my team

data collection, storage and operation on SQL.
