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:
However, through thorough
research, we found that the above systems have the following disadvantages:
 Firstly, manufacturers and authorized dealers only introduce their own
cosmetics. When a customer wants to see a company's product, they mus
find out through its website or go to its authorized agent, which makes it
very difficult for customers to compare their products with together .
 Finally, most online shopping websites have a simple interface and lack of
aesthetics leading to not attracting many customers.

1.3. The Proposed System
The website for selling computer components built and deployed by my team
can 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 cart
conveniently

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.
