ABSTRACT

Students have to search the internet each time to know about any news

updates like fee payment dates, exam results etc in the college website. The

project entitled “Student Alert System” is a system which sends latest news

updates from college website to a student, either via SMS or e-mail or both. The

system is developed so that students do not miss out on any alert and save their

valuable time. When they subscribe this service, they will be notified with latest

relevant news of their interest. Every student of the college can register in this

system to access this service.

The system extracts the latest news from the college website and sends

updates to the registered students. Only the registered students will receive the

notifications. The students subscribing this service will receive the alerts. Every

student will receive a username and password from the admin, to login in this

system. Notifications such as exam time table, fee details, syllabus, revaluation

results, exam results etc will be send as alerts to the students. Students can register

and choose the notifications they are interested in. They will receive the alerts for

their respective interests as chosen at the time of subscription. Facilities are

provided for the user to change their settings. The system groups the subscribers

according to their interest and securely sends alerts to all subscribers as and when

updates occur and keep the user informed. The user gets just the relevant news

without any glossy brochures or attention diverting advertisements.

CHAPTER 1

INTRODUCTION

Nowadays, mobile phones and internet are indispensable factors of our daily life.

This reality played a very important role in coming up with the proposed alert

system. When users subscribe this service, they will be notified with any latest

relevant news of their interest. For example the system will extract news from

other website and summaries it and send SMS & email to subscribers. Different

users will receive the news for their respective interests as chosen at the time of

subscription. The system groups the subscribers according to their interest. This

service provides a means to get news of the user interest and alerts the user

whenever an update occurs at the website.

1.1 OBJECTIVE

The objective of this project is to send alerts to students in the form of mail and

sms notifications from college website. The user can login using username and

password provided by admin. After login the user can make changes in the

settings if needed and select the type of notifications needed in the user profile

page.

The software has been developed using the most powerful and secured backend

MySQL and the most widely accepted front end tool JSP with HTML & servlet

coding behind.



1.2 OVERVIEW

The Student Alert System consists of the following implementation modules.

Admin module

User module

1.2.1 ADMIN MODULE

Tasks of admin

i) Confirm all the registered students

ii) Manage confirmed students

iii) Event management

iv) Send notification

Confirm students

The details of all registered students are listed in the confirm students

page, from which admin accepts the genuine users.

The admin mail the login information such as username and password to

the confirmed (accepted) students.

Manage students

All the confirmed (accepted) students are listed in this page.

Users listed in this page only receive alerts

Password and username verification are done from database created using

details of this page



Send notification

Notifications are extracted from college website using rss feed.

The admin receives all the notifications irrespective of the type of

notification.

Admin groups the notifications as public and group notifications.

Public notifications are for all users having common area of

interest.

Eg: SOE events

Group notifications are for group of users.

Eg: syllabus, timetable

Admin groups the news/events into different categories as

Exam results

Revaluation results

Fee details

Exam time table

Syllabus

School of engineering events

1.2.2 USER MODULE

User module consists of a user interface page. The user, with the username and

password provided by admin, reaches the user interface page.



The user interface page provides the following options.

Edit profile

-The user can edit his semester, email-id, mobile no.

Select the required notifications

Turn on/off SMS and mail notifications

Change password

Write comments

This system provides attractive design and proper arrangement of links and

images, which enables a browser to easily interpret and access the properties

of the site.



CHAPTER 2

SYSTEM ANALYSIS

System analysis is the process of gathering and interpreting facts, diagnosing

problems and using the information to recommend improvements on the system.

System analysis is a problem solving activity that requires intensive

communication between the system users and system developers.

System analysis or study is an important phase of any system development

process. The system is viewed as a whole, the inputs are identified and the system

is subjected to close study to identify the problem areas. The solutions are given

as a proposal. The proposal is reviewed on user request and suitable changes are

made. This loop ends as soon as the user is satisfied with the proposal.

2.1 EXISTING SYSTEM

In the current scenario a student has to search the college website each time to

know about any update which is time consuming. Moreover if a student doesn’t

have an internet connection it will not be easy to know about the updates of

college website, hence some students are not be informed about the about the

important events like fee payment date, results etc.

2.2 PROPOSED SYSTEM

The purpose of this project is to build software that alerts the students when an

update on an event or a new event is posted in college website. The student alert

system performs the following tasks:



(a) The system provides an interface for each user after registration.

(b) User can select the type of notification.

(c) User receives mail/sms notification when a news update comes in CUSAT

website.

(d) User can change password and edit the profile.

The main conceptual modules of the system are

1. System resources module

2. Profile Creation Module

3. Notification Module

Module 1: System resources module

The system resources that satisfy user profiles are determined by the specific

profiles. While registering user selects exact requirements of the profile. After

login user gets only those selected system resources. The system delivers relevant

data to the user when updates occur at those resources.

Module 2: Profile Creation Module

Admin specifies configurations of resources. At the time of profile creation, user

provides the mobile number and email id for the alerts.

Module 3: Notification Module

The module securely sends alerts to all subscribers as and when updates occur and

keep the user informed. The advantage of this system is that the user gets just the

relevant news without any glossy brochures or attention diverting advertisements.

CHAPTER 3

SYSTEM TOOLS

The various system tools that have been used in developing both the front end and

the back end of the project are being discussed in this chapter.

3.1 FRONT END

JSP, HTML, CSS, JAVA SCRIPT are utilised to implement the frontend.

3.1.1 JavaServer Pages (JSP)

Java Server Pages (JSP) is a technology for developing web pages that

support dynamic content which helps developers to insert java code in HTML

pages by making use of special JSP tags, most of which start with <% and end

with %>. A JavaServer Pages component is a type of Java servlet that is designed

to fulfil the role of a user interface for a Java web application. Web developers

write JSPs as text files that combine HTML or XHTML code, XML

elements, and embedded JSP actions and commands. Using JSP, one can collect

input from users through web page forms, present records from a database or

another source, and create web pages dynamically. JSP tags can be used for a

variety of purposes, such as retrieving information from a database or registering



user preferences, accessing JavaBeans components, passing control between

pages and sharing information between requests, pages etc.

JavaServer Pages are built on top of the Java Servlets API, so like Servlets, JSP

also has access to all the powerful Enterprise Java APIs, including JDBC, JNDI,

EJB, JAXP etc. JSP pages can be used in combination with servlets that handle

the business logic, the model supported by Java servlet template engines. JSP is

also an integral part of J2EE, a complete platform for enterprise class

applications. This means that JSP can play a part in the simplest applications to

the most complex and demanding.

JSP Architecture

The web server needs a JSP engine ie. container to process JSP pages. The JSP

container is responsible for intercepting requests for JSP pages. This tutorial

makes use of Apache which has built -in JSP container to support JSP pages

development. A JSP container works with the Web server to provide the runtime

environment and other services a JSP needs. It knows how to understand the

special elements that are part of JSP.

Following diagram shows the position of JSP container and JSP files in a Web

Application.



Fig 3.1: JSP container and JSP files

The major phases of JSP life cycle are very similar to Servlet Life Cycle and they

are as follows:

Fig 3.2: JSP life cycle

JSP Syntax



The Scriptlet:

A scriptlet can contain any number of JAVA language statements, variable or

method declarations, or expressions that are valid in the page scripting language.

Following is the syntax of Scriptlet:

<% code fragment %>

JSP Declarations:

A declaration declares one or more variables or methods that one can use in Java

code later in the JSP file. One must declare the variable or method before its use

in the JSP file.

Following is the syntax of JSP Declarations:

<%! declaration; [ declaration; ]+ ... %>

JSP Expression:

A JSP expression element contains a scripting language expression that is

evaluated, converted to a string, and inserted where the expression appears in the

JSP file. Because the value of an expression is converted to a string, one can use

an expression within a line of text, whether or not it is tagged with HTML, in a

JSP file. The expression element can contain any expression that is valid

according to the Java Language Specification but one cannot use a semicolon to

end an expression.

Following is the syntax of JSP Expression:



<%= expression %>

JSP Implicit Objects:

JSP supports nine automatically defined variables, which are also called implicit

objects. These variables are given in Fig. 2.5.

Fig. 3.3: JSP Objects

3.1.2 HTML (HyperText Markup Language)

HTML is a syntax used to format a text document on the web. These documents

are interpreted by web browsers such as Internet Explorer and Netscape

Navigator. HTML can be created as standard ASCII text with "tags" included to

pass on extra information about character formatting and page layout to a web



browser. HTML is written in the form of HTML elements consisting

of tags enclosed in angle brackets (like <html>), within the web page content.

HTML tags most commonly come in pairs like <h1> and </h1>, although some

tags represent empty elements and so are unpaired, for example <img>. The first

tag in a pair is the start tag, and the second tag is the end tag (they are also

called opening tags and closing tags). In between these tags web designers can

add text, further tags, comments and other types of text-based content. The

purpose of a web browser is to read HTML documents and compose them into

visible or audible web pages. The browser does not display the HTML tags, but

uses the tags to interpret the content of the page.HTML elements form the

building blocks of all websites. HTML allows images and objects to be embedded

and can be used to create interactive forms. It provides a means to

create structured documents by denoting structural semantics for text such as

headings, paragraphs, lists, links, quotes and other items.

3.1.3 CSS (Cascading Style Sheets)

CSS is a style sheet language used for describing the look and formatting of a

document written in a markup language. While most often used to style web

pages and interfaces written in HTML and XHTML, the language can be applied

to any kind of XML document, including plain XML, SVG and XUL. CSS is a

cornerstone specification of the web and almost all web pages use CSS style

sheets to describe their presentation. CSS is designed primarily to enable the

separation of document content from document presentation, including elements

such as the layout, colours, and fonts. This separation can improve

content accessibility, provide more flexibility and control in the specification of

presentation characteristics, enable multiple pages to share formatting, and reduce

complexity and repetition in the structural content (such as by allowing

for tableless web design). CSS can also allow the same markup page to be

presented in different styles for different rendering methods, such as on-screen, in

print, by voice (when read out by a speech-based browser or screen reader) and

on Braille-based, tactile devices. It can also be used to allow the web page to

display differently depending on the screen size or device on which it is being

viewed.

3.1.4 Java Script

JS is a dynamic computer programming language. It is most commonly used as

part of web browsers, whose implementations allow client-side scripts to interact

with the user, control the browser, communicate asynchronously, and alter

the document content that is displayed. It is also being used in server-side

programming, game development and the creation of desktop and mobile

applications. JavaScript is a prototype-based scripting language with dynamic

typing and has first-class functions. Its syntax was influenced by C. JavaScript

copies many names and naming conventions from Java, but the two languages are

otherwise unrelated and have very different semantics. The key design principles

within JavaScript are taken from the self and Scheme programming languages. It

is a multi-paradigm language, supporting object-oriented, imperative,

and functional programming styles. The application of JavaScript to use outside

of web pages for example, in PDF documents, site-specific browsers, and desktop

widgets is also significant.

3.2 BACK END

The back end is implemented using servlets and MySQL which is used to design

the databases.

3.2.1 MySQL

MySQL is the world's second most widely used open-source relational database

management system (RDBMS). The SQL phrase stands for Structured Query

Language. The MySQL development project has made its source code available

under the terms of the GNU General Public License, as well as under a variety

of proprietary agreements. MySQL was owned and sponsored by a single for-

profit firm, the Swedish company MySQL AB, now owned by Oracle

Corporation. MySQL is a popular choice of database for use in web applications,

and is a central component of the widely used LAMP (Linux, Apache,

MySQL, Perl/PHP/Python) open source web application software stack (and

other 'AMP' stacks). Free-software-open source projects that require a full-

featured database management system often use MySQL. For commercial use,

several paid editions are available, and offer additional functionality. Applications

which use MySQL databases include: TYPO3, MODx, Joomla, WordPress,

phpBB, Drupal and other software. MySQL is also used in many high-profile,

large-scale websites, including Wikipedia, Google(though not for searches),

Facebook, Twitter,

Flickr, and YouTube.

SERVLETS

Servlets are programs that run on a Web or application server and act as a middle

layer between a requests coming from a Web browser or other HTTP client and

databases or applications on the HTTP server. Their job is to perform the

following tasks, as illustrated in Fig. 2.6.

Fig.3.4: Servlet tasks

Using Servlets, one can collect input from users through web page forms,

present records from a database or another source, and create web pages

dynamically .Java Servlets often serve the same purpose as programs

implemented using the Common Gateway Interface (CGI). But Servlets offer

several advantages in comparison with the CGI.

Performance is significantly better.

Servlets execute within the address space of a Web server. It is not

necessary to create a separate process to handle each client request.

Servlets are platform-independent because they are written in Java.

Java security manager on the server enforces a set of restrictions to



protect the resources on a server machine. So servlets are trusted.

The full functionality of the Java class libraries is available to a

servlet. It can communicate with applets, databases, or other software via

the sockets and RMI mechanisms that you have seen already.

Servlets Architecture:

Following diagram shows the position of Servlets in a Web Application.

Fig.3.5: Position of Servlets in a Web Application

Mail API

The JavaMail is an API that is used to compose, write and read electronic

messages (emails). The JavaMail API provides protocol-independent and

platform-independent framework for sending and receiving mails.

The javax.mail and javax.mail.activation packages contain the core classes of



JavaMail API. The JavaMail facility can be applied to many events. It can be used

at the time of registering the user (sending notification such as thanks for your

interest to my site), forgot password (sending password to the users email id),

sending notifications for important updates etc. So there can be various usage of

JavaMail API. One can send email by using the SMTP server of gmail by SSL

(Secured Socket Layer). SSL is basically used for security for sending email

through gmail server.

For sending the email using JavaMail API, the two jar files are to be loaded.

mail.jar

activation.jar

There are some protocols that are used in JavaMail API.

SMTP

POP

IMAP

MIME

NNTP and others

The java application uses JavaMail API to compose, send and receive emails.

The JavaMail API uses SPI (Service Provider Interfaces) that provides the

intermediatory services to the java application to deal with the different

protocols. There are three steps to send email using JavaMail.

They are as follows:



1. Get the session object that stores all the information of host like host name,

username, password etc.

2.Compose the message

3.Send the message

SMS API

An SMS gateway allows a computer to send or receive Short Message

Service (SMS) transmissions to or from a telecommunications network. Most

messages are eventually routed into the mobile phone networks. Many SMS

gateways support media conversion from email and other formats. An SMS

gateway typically sits between the end user who needs to send/receive SMS and a

mobile network's SMSC. Such gateways provide a choice of protocols including

HTTP, SMTP, Short Message Peer-to-Peer and web services. Providers of SMS

gateway services include SMS aggregators and mobile operators. SMS gateways

are also available as part of messaging services such as AOL, ICQ and others. An

SMS gateway connects with (i) mobile network SMSCs in order to send/receive

messages and/or (ii) other SMS gateways in order to reach mobile subscribers on

multiple mobile networks. It is therefore possible that an SMS gateway has a

combination of mobile network SMSC connections and connections with other

SMS gateways in order to provide its services. However, there is the increasing

potential for delivery problems with SMS the greater the number of SMS

gateways in the delivery chain.

Text messages can be sent from a personal computer to mobile devices via an

SMS gateway. The messages must be sent in ASCII "text-only" mode. If they are

sent in HTML mode, or using non-ASCII characters, they will most likely appear

as nonsense on the recipient's mobile telephone. Before the message can be sent,

one must determine the domain of the mobile carrier's SMS gateway. To

determine the SMS gateway domain, e.g., txt.att.net, may require research, as

mobile telephone users typically do not know this information when they provide

their telephone number and due to number portability the number may no longer

be associated with the carrier that originally issued it. The country code is not

needed, as the 10-digit telephone number, together with the email domain, are

sufficient to send the email from any location in the world. It is useful to perform

a character count to ensure that it is within the 160-character limit. If it exceeds

the limit, the SMS gateway should break the message into a set of consecutive

160-character, or shorter, messages to the mobile equipment, although the breaks

may occur in the middle of words. A message sent with an email client can be

simultaneously addressed to multiple mobile telephones, whereas text messages

sent in the usual manner between mobile telephones can only be sent to a single

recipient.

CHAPTER 4

SYSTEM DESIGN

System design is the solution for the creation of a new system. This phase focuses

on the detailed implementation of the feasible system. It emphasis on translating

design specifications to performance specification. System design has two phases

of development

Logical design

Physical design

During logical design phase the analyst describes inputs (sources), outputs

(destinations), databases (data sores) and procedures (data flows) all in a format

that meets the user requirements. The analyst also specifies the needs of the user

at a level that virtually determines the information flow in and out of the system

and the data resources. Here the logical design is done through data flow diagrams

and database design.

The physical design is followed by physical design or coding. Physical design

produces the working system by defining the design specifications, which specify

exactly what the candidate system must do. The programmers write the necessary

programs that accept input from the user, perform necessary processing on

accepted data and produce the required report on a hard copy or display it on the

screen.



4.1 INPUT AND OUTPUT DESIGN

INPUT DESIGN:

Input design is the link that ties the information system into the world of

its users. The input design involves determining the inputs, validating the data,

minimizing the data entry and provides a multi-user facility. Inaccurate inputs are

the most common cause of errors in data processing. Errors entered by the data

entry operators can be controlled by input design. The user-originated inputs are

converted to a computer based format in the input design. Input data are collected

and organized into groups of similar data. Once identified, the appropriate input

media are selected for processing. All the input data are validated and if any data

violates any conditions, the user is warned by a message. If the data satisfies all

the conditions, it is transferred to the appropriate tables in the database. In this

project the student details are to be entered at the time of registration. A page is

designed for this purpose which is user friendly and easy to use. The design is

done such that users get appropriate messages when exceptions occur.

OUTPUT DESIGN:

Computer output is the most important and direct source of information to the

user. Output design is a very important phase since the output needs to be in an

efficient manner. Efficient and intelligible output design improves the system

relationship with the user and helps in decision making. Allowing the user to view

the sample screen is important because the user is the ultimate judge of the quality

of output. The output module of this system is the selected notifications.



4.2 DATABASE

DATABASE DESIGN:

Databases are the storehouses of data used in the software systems. The data is

stored in tables inside the database. Several tables are created for the manipulation

of the data for the system. Two essential settings for a database are

Primary Key- the field that is unique for all the record occurrences.

Foreign Key-the field used to set relation between tables.

Normalization is a technique to avoid redundancy in the tables.

4.3 DATA FLOW DIAGRAM

A Data Flow Diagram (DFD) is a structured analysis and design tool that can be

used for flowcharting. A DFD is a network that describes the flow of data and the

processes that change or transform the data throughout a system. This network is

constructed by using a set of symbols that do not imply any physical

implementation. It has the purpose of clarifying system requirements and

identifying major transformations. So it is the starting point of the design

phase that functionally decomposes the requirements specifications down to

the lowest level of detail. DFD can be considered to an abstraction of the logic of

an information-oriented or a process-oriented system flow-chart. For these

reasons DFD’s are often referred to as logical data flow diagrams.

CONTEXT LEVEL DIAGRAM (LEVEL 0)

The Top-level diagram is often called a context level diagram. It is also called 0

level data flow diagram. It contains a single process, but it plays a very



important role in studying the current system. The context diagram

determines the boundaries. Anything that is not inside the process identified in

the context diagram will not be part of the system study. The external

elements, that are the sources and sinks function will not be studied in detail

in the context level data flow diagram.

EXTERNAL ENTITY

An external entity is a source or destination of a data flow. Only those entities

which originate or receive data are represented on a data flow diagram. The

symbol used is a rectangular box.

PROCESS

A process shows a transformation or manipulation of data flow within the

system. The symbol used is an oval shape.

DATAFLOW

The data flow shows the flow of information from a source to its destination. Data

flow is represented by a line, with arrowheads showing the direction of flow.

Information always flows to or from a process and may be written, verbal or

electronic. Each data flow may be referenced by the processes or data stores at its

head and tail, or by a description of its contents.

DATA STORE

A data store is a holding place for information within the system: It is represented



by an open ended narrow rectangle. Data stores may be long-term files such as

sales ledgers, or may be short-term accumulations: for example batches of

documents that are waiting to be processed. Each data store should be given a

reference followed by an arbitrary number.

SYSTEM IMPLEMENTATION

LOGIN

The login page redirects user to the user interface page and admin to the admin

interface page.The login thus acts as the homepage. It provides additional links

such as About the project, Department, Map, Gallery etc.

<p class="latestnews"> Nowadays, mobile phones and internet are indispensable factors

of our daily life. This reality played a very important role in coming up with the proposed alert

system. When users subscribe this service, they will be notified with any latest relevant news of

their interest. For example the system will extract news from other website and summaries it and

send SMS & email to subscribers. Different users will receive the news for their respective

interests as chosen at the time of subscription. The system groups the subscribers according to

their interest. This service provides a means to get news of the user interest and alerts the user

whenever an update occurs at the website. </p>

SYSTEM TESTING

Testing is a set activity that can be planned and conducted systematically. Testing

begins at the module level and work towards the integration of entire computers

based system. For testing our software we test each and every path that user can

go at any point in the lifetime of the system .Nothing is complete without testing,

as it is vital success of the system.

There are several rules that can serve as testing objectives, they are

1. Testing is a process of executing a program with the intent of finding an error

2. A good test case is one that has high probability of finding an undiscovered

error.

3. A successful test is one that uncovers an undiscovered error.

If testing is conducted successfully according to the objectives as stated above, it

would uncover errors in the software. Also testing demonstrates that software

functions appear to the working according to the specification, that performance

requirements appear to have been met.

The entire testing process can be divided into 3 phases

1. Unit Testing

2. Integration Testing

3. Final/ System testing



6.1 UNIT TESTING

In unit testing we had tested every single part that is the forms of the software.

We did this simultaneously while the project is being built. The test data was

given to each and every module in all respects and got the desired output. Each

module has been tested found working properly. Then the various sets of input

values are devised with various combinations of inputs being out of range.

6.2 INTEGRATION TESTING

In this, all the Code Modules were tested individually one after the other.

Software is written in JSP, so it is a collection of pages. So we tested each and

every page carefully with various sets of input values with various combinations

of inputs being out of range. And we found all the components in the module

are working perfectly. In our case all the modules were combined and given the

test data. The combined module works successfully without any side effect on

other programs.

6.3. FINAL/SYSTEM TESTING

In this the entire system was tested as a whole with all forms, code, modules and

class modules. Popularly known as Black Box testing or system testing, it focus

on the functional requirement of the software. That is, Black Box testing enables

the software engineer to derive sets of input conditions that will fully exercise all

functional requirements for a program. Black Box testing attempts to find errors

in: incorrect or missing functions, interface errors, errors in data structures or



external database access, performance errors, initialization errors and termination

errors. Various sets of input values are devised with various combinations of

inputs being out of range.

CHAPTER 7

CONCLUSION

The project report entitled ”STUDENT ALERT SYSTEM” has been completed.

The system has been developed with much care that it is free of errors and at the

same time it is efficient and less time consuming. The purpose of this project

was to send sms and mail alerts to the students when there is any new update

in the college website and also provide facilities for selecting required

notifications.

The important thing is that the system is robust. We have tried our level best to

make the system as dynamic as possible. This project helped us in gaining

valuable information on several topics like web page design principle, handling

the user interface in a powerful way, to access the various pages across the

application etc. The entire system is secured. Also JSP and HTML are gaining

rapid acceptance as means to provide dynamic content on the Internet.

Running from the server in the secure manner, the application processes are also

limitless.

More than anything this project has given us great satisfaction in having designed

an application, which processes information from university to the students. This

system transfers the user’s needs into a software solution and saves their precious

time .This online system can be approved by the college and if it is implemented

it will be much useful for student.



There is a scope for further development in our project in terms of functionality

for users. The admin can track each user by their register no. and can be provided

only their specific details. Also other facilities such as hostel allotment, digital

library facility can be integrated with this project so that it becomes a single stop

solution for the students. Student communication with the admin as well as other

students can also be implemented.
