Performing the administrative management for professional activities of the

company.

The reason for chosing of project:

Today, information technology (IT) is one of the most important driving

force of social - economic development. Using IT aiming at contribution on

liberating labor forces and of any intellectual field in general and online sale

businesses. Recognizing the role of IT, businesses soon reach it in order to meet the

demands of people.

Standardization of business management processes, application of

information technology in business management to standardize the business

processes, bringing the process into production - business. Increasing the

competitiveness of enterprises in parallel with the above factors, the supply and use

of information timely and accurately is one of the most important factors in the

competitive economy today,creating the ability to integrate into world economy,

especially during periods of globalization economy today; enhancing business

image in the eyes of its counterparts and investors. IT application, providing clear

information on finance will create confidence for partners at home and abroad ,

facilitate the cooperation business, create the basis and improve the ability to

provide value-added services. The use of achievements of IT in management helps

businesses to increase adaptation to the market, to be ready to expand the types of

services to customers, to increase its access to markets and customers.

IT is one of the new breakthrough of the world to provide quickly the latest

information at home and to help man to reach any kind of information. For

example, online sales have contributed indispensable for Vietnam market todayproviding essential items to consumers and reducing travel costs for customers.

It has the benefits as follows:

- Providing quickly full information to customers .

- Providing services to customers in select, order at anytime and at any place.

- Easily monitoring and receiving feedback from customers.

effectively.

- Accessing to the market in the world.

Based on the characteristics of each sales online website, encyclopedias

Genetic group of students has established a website to

provide online sales of computers that have been being on the market today in order

to renew the motto shopping customers.

This site focuses on program management, providing customers with

information about the products that customers want to choose. Thus website has

been founded for management and making up new items.

1.2. Project feasibility

Feasibility

Generally, buiding a website system we must have main purpose as follows:

- Benefits in terms of transaction: Increasing fast, convenient, accurate and

secure transaction capability.

- Economic benefits: Reducing the number of employees, reducing cost,

increasing revenue of company

- Overcoming many shortcomings of the system being implemented, to

support long-term development strategies; to support former system.

Economic Feasibility

Economic feasibility is a very important element that needs to be considered in

planning and building an information system. So, this is one of parts we much

concentrate on when developing the system too.

Economic feasibility is the cost that you must estimate for hardware,

software or something relating to software development (for example: software

copyrights). Sometimes, economic feasibility is the cost that the customers, who use

the system, must overshadow for short-time/ long-time in operating system until

that system can be run and applied. This is one of the elements that must be

pondered carefully and will decide should the program proceed any further?

Technical Feasibility

7/122

Basic Knowledgement

A large part of determining resources has to be done with assessing technical

feasibility. The analysis must find out whether current technical resources can be

upgraded or added to in a manner that fulfills the request under consideration.

However, sometimes add on to existing system are costly not worth while, simply

because they must meet needs inefficiently. If the existing systems can not be added

onto, then the next question becomes whether there is technology in existence that

meets the specification.

CHAPTER II: INTRODUCTION TO TECHNOLOGY

2.1. Database Management System Assessment

The Database Management System (DBMS) is used to organize the data in a

database, it can store arrange and search information, sometimes it can access

concurrently into many database through a public field.

2.1.1. Definition about Database

Database: A stock about a subject which is organized logically in order

manage and search easily. Any data stock satisfies

this requirement can be considered as a database. Normally the information indatabase is divided into the same organized pieces of records.

Table is a basic component in relational database management system. Table

is built up when ralative information is arranged in rows and columns.

Rows are correlative with records and columns are correlative with fields.

Record: In database management system, record is the most fully unit of

data,

which is stored when data is given a name. In a database table, a data record

means row. Record stored all the information which in is concerned which

DBMS. Record is displayed in 2 ways: Input data form and data table. Data record

is available in horizontal and each data is a column.

Field: In DBMS, this space is for a piece of data of record. Field is

correlative with column.

2.1.2. The Database Management System

The database management system (DBMS) is software that enable

users to define, create and maintain the database and which provides controlled

access to this database.

The DBMS is the software that interacts with the users application programs and

11


12/122

Basic Knowledgement

the database Typically, a DBMS provides the following facilities:

It allows users to define the database, usually though a Data Definition

Language (DLL). The DLL allows users to specify the data types and

structures and the constraints on the data to be stored in the database.

It allows user to insert, update, delete anh retrieve data from the database,

usually through a Data Manipulation Language (DML). Having a central

repository for all data and data descriptions allows the DML to provide a general

enquiry facility to the data, being called a query language.

It provides controlled access to the database.

For example, it may provide:

A security system, which prevent unauthorized user form accessing the database.

An integrity system, which maintains the consistency of stored data.

A concurrency control system, which allows shared access of the database.

A recovery control system, which restores the database to a previous consistent state

following a hardware or software failure.

With these functionalities, the DBMS is an extremely useful tool. That is why

DBMS is widely used in programming.

2.2. Other technologies assessment

Today, with the development of information technology, computer plays an

important role in the technological science revolution. Computer brings to people

interesting programs, which can apply for education, entertainment and many other

areas. Moreover, people can ask computer to execute something for then by creating

programs. Certainly, our ability could not solve billions of comples digits and sort

them in the particular orders. So to make programs more easily, more efficiently,

programming language were invented. There are so many programming language

like.

C #

12


13/122

Basic Knowledgement

C# is a high level language. It is the fastest and easiest way to

create applications for windows. C# provides you with a complete set of tools to

simplify rapid application development. It is used to create Graphical User Interface

(GUI). It contains several hundred statements, functions, and keywords, many of

which ralate directly to the Windows Graphical User Interface rather than writing

numerous lines of code to describe the appearance and location of interface

elements, you simple drag and drop rebuilt objects into place on the screen.

ASP.net

Active Server Page is Microsofts server- side technology for dynamically

generated web pages. Page can be generated by mixing server-side scripting code

with HTML and client-side code. Programming ASP website is made easier by

various built-in objects, such as cookie based session object that maintains

variables from page to page. ASP has some advantages like.

Script Language-independent: ASP allows using VBScript, Jscript or Perl

(Perlscript) and have it executed on the server without having to learn another

scripting language.

Utilize COM components from your web server-reuse any functionality built using

COM components for your companys software product can on your website

though ASP pages. ASP is the connection between the conventional software anh

the website.

ODBC links to any data source

You can use server-side Active component (DLLS)

ASP also several restrictions such as only run on Windows NT/IIS

Microsoft SQL Server 2005

Microsoft Structured Query Language (SQL) 2005 is the latest generation

of the popular SQL Server product line and the second ralease since core

reengineering that produced server 7.0, released in 1999. This latest ralease of

SQL Servers add the native Extensible Markup Language (XML) support,

enhanced Online Analytical Process (OLAP), data-mining capabilities, platform

support for Windows XP, integration with Windows XP Active Directory, and

numerous performance, usability anh programming enhancements, SQL Server are

13


14/122

Basic Knowledgement

available on 6 different editions to meet all level of application development and

delivery.

SQL Server 2005 Enterprise Edition

SQL Server 2005 Standard Edition

SQL Server 2005 personal Edition

SQL Server 2005 Developer Edition

SQL Server 2005 for Windows CE Edition

SQL Server 2005 Destop Engine (MSDE)

SQL Server is the first release designed and built to take advantage of Windows

XP with support for up to 32 processors and 64GB of memory running on

Windows XP Datacenter Server Windows XP Active Directory integration added

enhanced servers and security management features to SQL Server. SQL Server

2005 support the latest release of OLAP, now called the analysis services. This

provides numerous wizards for ease of use anh the setup of OLAP and new data

mining solutions.

One of the more publicized additions to SQL Server is its native support for

XML document an important requirement because XML becomes the language of

choice for many business systems anh a fundamental architecture component of

Microsoft.net.

SQL Server is the first released member of the .NET Enterprise Server

family and offers numerous advantages to organizations considering migration to

this new platform. Enhancement in reliability, scalability, performance and

administration, along with strong compatibility with previous versions, make this

release a strong candicate for early adoption into SQL Server 7.0 environmentsand an immediate migration from organizations running on SQL Server 6.5 native

XML support on SQL Server 2005 will help many organization begin

implementing this technology, which is quickly becoming a standard to both

external anh internal systems including E-commerce, Web application services

and line-of-business applications.

For all these reasons above, we have chosen SQL Server 2005 for our

projects.
