ừ kh a: Social network platform, REST Architecture Style, Software Development Life Cycle

(SDLC)

Abstract: The purpose of this study is to scrutinize the reasons, benefits, problems and

solutions encountered in the usage of social networ ing based on opinions of Hanoi University’s

students, thence, we can create a useful social media web. This study was conducted using the

questionnaire technique to collect data. Therefore, questionnaire was held with 100 random students.

Based on the study’s results, it was found that there are various reasons why students use social

media such as connecting and keeping in touch with friends and family easily, sharing emotion or

story with others and reducing stress. Another ey point in this survey is the students’ opinions about

social networking, whether it is good or not. If it does not, what is the solution needed to improve

social networking. As such, it is believed that this report can serve as a prototype as well as a potential

stimulus for larger and further studies in the future.

I. INTRODUCTION

With the explosion of internet, social networks are becoming increasingly popular in

our society. Thanks to social media, we can communicate easily with others regardless of

geographical distance and time. However, social network platforms also bring many troubles

for users as wel as administrators such as security errors, annoying advertisements, slow

processing speed and difficult interface to use. Thus, based on collected users‘ requirements,

we aim to conduct Social Media Web Project which creates a simple and convenient social

media web and focuses more on restful architecture.

II. METHODS AND RESULTS

Software Development Life Cycle (SDLC) is the development approach for our project

which is a process used by the software industry to design, develop and test high quality

softwares. The SDLC aims to produce a high-quality software that meets or exceeds customer

expectations, reaches completion within times and cost estimatesInvalid source specified..

SDLC divides development processes into the following five phases: analysis, design,

implementation, testing, and maintenance.

A. Analysis and Requirement

1. Methods

The data used in this report is acquired from a survey carried out within Hanoi

University. At the beginning, a questionnaire consisting of 8 questions was designed to

capture requirements of users with a social media web. In the next step, about 100 students of

different ages and academic years were randomly selected, and each of them respectively

asked the 8 questions. Therefore, we were confident that the data obtained achieved a fairly

high level of genuineness.

2. Results

This section outlines the results of the survey conducted to discover HANU students‘

opinions of the usage of social networking. With a view to determining the kinds of functions

of social networking which are popular among the students of Hanoi University, a great deal

of the typical features were listed in the questionnaire. In order to simplify the data

interpretation, the different requirements have been combined and labeled under the headings

― user interface‖, ―security‖ and ―communication and interaction tool‖.

The types of requirement

Figure 14: The percentage of the students setting the requirements

As can be seen from Figure 1, the number of the students desiring good communication

and interaction tools( such as chat box, status post) occupies the first place, reaching 96% of

the total. Meanwhile, the figure for the students requiring user interface ranks the second, with

84%, is significantly more than that of security (only at 46%).

Especially, the required user interface is clear, convenient and easy to use and includes

different tabs with title according to its function. With regard to security, every user has a

distinct account and individual page, which helps users to avoid being hacked individual

information and account.

Figure 2: The percentage of the students' attitudes towards social media' effects

Turning to the social network platforms‘ effects, more than a half (51%) of those who

responded were of the opinion that social media has both negative and positive impacts on

them. Whereas, 39% of the people replied that social networking is positive, and, only 10%

believed that it has negative influences.

Therefore, we believe that creating a social network platform is really useful, which

may meet the essential needs of people.

B. Design

1. Methods

Based on these above requirements, design provides a comprehensive design overview

of the system, using a number of different design views to depict different aspects of the

system, such as Entity Relationship Diagram and Data Flow Diagram. It is intended to capture

and convey the significant design decisions which have been made on the system.

2. Results

specified. .Creating the necessary entities( such as comment, status, profile, like) helps us to

develop useful communication and interaction functions for users.

Our project has two main processes including chatting and posting status, and the

following data flow diagrams (DFDs) map out the flow of information for these two processes

Invalid source specified.. Chatting and posting status are two vital processes which assist us

in creating simple and user-friendly social media web.

C. Implementation

1. Methods

To develop our social media web, we use Tomcat version 9.0 web server, MySQL

database server and Java programming language. Besides, we also attach special importance

to using Restful architecture that defines the set of rules to be used for creating web services.

Web services which follow the REST architectural style are known as RESTful web services.

It allows requesting systems to access and manipulate web resources by using a uniform and

predefined set of rules. Interaction in REST based systems happen through Internet‘s

Hypertext Transfer Protocol (HTTP)Invalid source specified.. In our project, we use jax-rs

interface and jersey which are implementation of jax-rs to create Rest APIs.

2. Results

To concretize REST architecture style, we exemplify the following profile rest. The

profile model helps to declare essential attributes for profile of user. The profile DAO roles

play as data layer for profile of user in database. Profile DAO conforms to CRUD( create,

read, update and delete). Next, we provide profile service handling business logic( post, get,

update and delete data from data layer). Moreover, profile service also helps get expected data

range or data by year. The profile resource implements sufficiently get, post, update and

delete method. Profile resource returns both JSON data and XML data, conforms to REST

Architecture Style. Finally, we use postman to get JSON data from our social media web.

In terms of social media web for users, we represent user interface of two main pages

including chatting and posting status.

D. Testing

1. Methods

To test software, we use Junit which is a Regression Testing Framework used by

developers to implement unit testing in Java, and accelerate programming speed and increase

the quality of codeInvalid source specified.. JUnit Framework can be easily integrated with

Eclipse.

2. Results

The below figure 7 shows our Junit Test demo for Comment Service with testGet

method to check selecting comment from database, which assists in increasing the quality of

code.

III. DISCUSSION

This study has proposed the simple and user-friendly social network platform which

helps users can communicate and interact with others more conveniently. Moreover, our

project applies REST Architecture Style to build API easily. However, our project is still

limited, social media web is quite simple and has limitation in functions. The potential of

application of social networking platforms is that they assist not only in communicating and

interacting better but also in growing marketing. Increasing numbers of businesses in various

industries have already integrated or plan to integrate social media applications into their

marketing programs. Besides, we will develope more about maintance pharse by updating the

code according to the changes taking place in user end environment or technology. This topic

is of interest for further research and implementation.

IV. CONCLUSION

In short, while studying users‘ usage of social media, we concluded that social network

is a double - edged sword, therefore, in order to make the benefits outweigh the dissavantages,

158

creating a convenient and friendly social media web for users are really essential. This paper

has discussed about the development approach - Software Development Life Cycle (SDLC)

which helps us to design, develop and test high-quality softwares, that meets or exceeds

customer expectations. It is hoped that in the future, where would be many more further

project about social media so as to help users to have better social network platforms.
