1.Problem Definition

1.1 Problem Abstraction

Today, when the demand for exchanging and searching information of

people is increasing, almost everyone needs to equip themselves with a computer

to be able to serve the individual needs of each person Therefore, this website

was born to serve the needs of each person rising to offering customers quality

products and know how to protect and use in a way that results.

Sales website is an exchange tool between seller and buyer Where sellers

can introduce products to buyers in need and fulfill their needs online So just a

few clicks, users were able to complete the task buyer's products.

Facing the needs of individuals and businesses website design as well as the

passion for web application programming We chose the topic: "Website Selling

computer Components" to be the subject of Project I.

1.2 The Current System

The idea of a selling computer components online website is not new, for those who surf the web with just one click can find many websites selling computer components For example, when you need to buy a computer

components, you can go to many websites and some big websites are:

https://www.hanoicomputer.vn/ , https://www.anphatpc.com.vn/… However, through thoroughresearch, we found that the above systems have the following disadvantages:

Firstly, manufacturers and authorized dealers only introduce their owncosmetics When a customer wants to see a company's product, they musfind out through its website or go to its authorized agent, which makes itvery difficult for customers to compare their products with together

Finally, most online shopping websites have a simple interface and lack

1.3 The Proposed System

The website for selling computer components built and deployed by my teacan be described as an online electric supermarket In that online supermarket,

w will let component companies rent places and business methods In short, we are not the direct suppliers of the product, we only create an intermediary

environment between phone companies and customers, then each order or question will be directed directly to the corresponding carrier requested by that customer

This new system will have the following functions:

For consumers: Creating favorable conditions for consumers to be able to evaluate and search for cosmetics of the same manufacturer

or different brands, so that they can choose for themselves the right product

For manufacturers: the website helps promote the image of the manufacturer More important than the website is where it can sell its products in the fastest and most effective way In addition, the focus o many firms enables each firm to capture the needs of customers for it products with other firms devising new sales strategies to compete with other brands

Compared to the old system, this new system has overcome and added the following new functions:

Eye-catching interface, suitable for the aesthetic of many different social classes

Search function by cosmetic type, cosmetic name, manufacturer, quick search by price

Function allows customers to manage accounts and shopping cartconveniently

1.4 Boundaries of the System

Currently, due to objective conditions, the system still has no payment function Search function by product name is still difficult and not real accurate

The scope of the project is to deploy in large cities, where information systems are relatively developed Users are those who access the network In addition, due to weak resources, limited time and inexperience, some features such as security, database design and interaction between website and users are limited
