ABSTRACT

The purpose of this study was to investigate to build a website that acts as a social network for students and manager of companies The website provides environment for students to test knowledge and skills It also helps managers as a channel for contacting students in easy way Another aim was to build a big and plentiful data source of multiple choice questions by contributing from manager users of system Finally, the process of building a website was pointed out

To accomplish, software development process was applied to build a website The first step, system requirements specification was done There were many requirements they consisted of functional and non-functional requirements listed The second, database was analyzed and designed The website used MySQL – an open source relation database management system – to manage database The works of collecting data have been started when database was created The third, website was designed layout and implemented The CakePHP framework was used as platform for

developing The fourth, from the first version to existing version were tested and tried

by my classmates they helped me point out system logic errors and graphical user interface errors The works of upgrading and errors correcting were consecutively done The website could be applied in fact from existing version but it still has been upgrading and developing with more function

The results of this study were a powerful website with many functions and friendly user interface The database was also contributed more than 200 multiple choice questions Besides, finishing this project gave me more experiences and skills for website development as well as system development I also enriched my knowledge and tried solve problems in fact

INTRODUCTION 1.1 Motivation

Nowadays, information technology is applied in large range of real life from

economics, education, healthcare, agriculture to geotechnical, military, Astronomers

It helps people not only in communication but also solve complicated problems

Power of information technology is uncompromising Trying to use benefit of

information technology is always making more benefits

In higher education, on the last year at university, most of students must find

internship address to practice as a required subject In my school, University of

Engineering and Technology, students face many difficulties in work finding

appropriate address as well as how easy to contact with manager of companies or supervisors Besides, many companies also face with difficulties about how to find excellent candidates and how to contact them in convenient way

From this fact, we have developed a system call “Internship Social Network” for students and manager of companies to solve these problems System enables managers

to public their company notices and reports Besides, managers could also add

questions to system Student users could take part in exam that generated by system and get points from this work These point values could be useful information for managers to choose appropriate students for their work

1.2 Contribution and Thesis Overview

This thesis describes about process building a website call “Internship Social

Network” using framework CakePHP Website provides environment for student who want to find companies to intern and for manager of companies to find student who is suitable for job Website acts as a social network and a contest tool Students after signing up and update profile could take part in examination to test their knowledge Managers after sign up and update profile could post notice about recruitment and report about results of last recruitment as well as contributing question to system Website is designed for a moderate volume of users I have integrated FCK Editor in

website for easy to create a post and add question on manager session and admin session

The rest of this thesis is organized as follows:

Chapter 2, related works are presented First of all, I present about some basic

concepts that relate to my system The next, I mention about website freelancer.com –

a website in which users could post a project to hire or apply a project And the last, I refer to vietnamworks.com – a website for people to create curriculum vitae and find jobs

Chapter 3 shows the process of doing analysis and design of system On analysis phase, the first thing I present is the work of collecting system’s requirements they consist of functional requirements and non-functional requirements The second, I show use-case models that are suggested for system On design phase, I mention about entities on system, the relationships between them and structure of database that used

On the last of chapter, I discuss about system modules consisting of structure and function of these modules

Chapter 4 is devoted to mention about technology that I choose for my project I will discuss a little bit about CakePHP framework I show structure of CakePHP, how installing and using CakePHP framework At the end of chapter, I cover about MVC Model on web development

Chapter 5 is spent to present about implementation of website As well as showing user interface of system It will show what users really see and work with on system The last thing I cover about sample data that I have used

2.1 Basic Knowledge

Client-server system : Client

to server, for example retrieve homepage of website After that, server accepts query and analysis If needed, server will use database and retrieve

database or update database, it depends on what kind of client’s query After

retrieving data from database server will response to client Among connection, client and server use “3-way hands shake” to connect with each other

FigurSocial networks: A social network is a social structure of people in a electronic

environment There are many dyadic ties between users of social network, it makes social space Do not like a regular website, social network is system that enables users

to make social values between users [

3.1.1 Functional Requirements Specification

To build system, I have put myself on the position of users and administrator to

proposal useful requirements These functional requirements are suggested

 System developed for student, manager of companies and admin

 System enables guests to register new account, log in to system to use system function, logout when finish session works

 System enables manager users post to system their notice about their

recruitment reports and requirements and also manage these notice like editing

or deleting Student can see post of managers as a list Admin could delete any post that created by manager users

 System enables student users to take part in contest in multiple-choice format Students do not need to do repeat question and students get point from a right answer After students complete the test, not display answer of separate

question Just give him score

 Companies’ manager users could add questions to system Questions must be

in multiple-choice format with four options of answer On work creating
