ABSTRACT

The demand of manage information is highly in every organization. Management
information effectively help reduce cost, time and avoid redundancy data. To
understand deeply how benefit a database can bring to an organization and the process
to build a database, we decided to build a Market Online Management Project. With
the aim to help clinics easily in managing their business, take care of customers, … We
know within building this project, there will be mistakes that we can solve but it is the
chance for us to achieve knowledge and skills which are precious tools in the future and
we will make this project as good as we can.


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
Understanding the process of building a database from idea creation, modeling,
data collection, storage and operation on SQL.
Designing a software based on the available data.
Project is the basis that my group can continue to develop in the following
subjects.
