1.2Existing System:

Since the facility head is the chief controlling authority in the department, a

schedule is to be prepared for him and to be maintained permanently.

The data is maintained manually where there is a possibility for loss of data.

It is a very tedious process

1.3 Proposed System:

This system is proposed for the work to be done in sophisticated

manner instead of investing their valuable time.

Using this system the Admin can maintain up to date information

without taking the risk of maintaining in manually.

This System will help the facility heads to perform their duties

effectively

2.3 Software Description

J2SE development kit overview:

There are two principal products in the Java SE platform family: Java SE Runtime

Environment (JRE) and Java Development Kit (JDK).

Java Runtime Environment (JRE)

The Java Runtime Environment (JRE) provides the libraries, the Java Virtual

Machine, and other components to run applets and applications written in the Java

programming language. In addition, two key deployment technologies are part of

the JRE: Java Plug-in, which enables applets to run in popular browsers; and Java

Web Start, which deploys standalone applications over a network. It is also the

foundation for the technologies in the Java 2 Platform, Enterprise Edition (J2EE)

for enterprise software development and deployment. The JRE does not contain

3


4/80

tools and utilities such as compilers or debuggers for developing applets and

applications.

Java Development Kit (JDK)

The JDK is a superset of the JRE, and contains everything that is in the JRE, plus

tools such as the compilers and debuggers necessity.

Java Server Pages (JSP):

Java Server Pages (JSP) technology provides a simplified, fast way to create web

pages that display dynamically-generated content. The JSP specification, developed

through an industry-wide initiative led by Sun Microsystems, defines the interaction

between the server and the JSP page, and describes the format and syntax of the page.

JSPs have dynamic scripting capability that works in tandem with HTML code,

separating the page logic from the static elements -- the actual design and display of

the page -- to help make the HTML more functional(i.e. dynamic database queries).

Java Server Pages (JSP) technology enables us to rapidly develop and easily maintain,

information-rich, dynamic Web pages that leverage existing business systems. As part

of the Java technology family, JSP technology enables rapid development of Web-

based applications that are platform independent. JSP technology separates the user

interface from content generation, enabling designers to change the overall page

layout without altering the underlying dynamic content.

Benefits for Developers:

With a familiar background with HTML, we can:

Use JSP technology without having to learn the Java language: You can use

JSP technology without learning how to write Java scriptlets. Although scriptlets are

no longer required to generate dynamic content, they are still supported to provide

backward compatibility.

Extend the JSP language: Java tag library developers and designers can extend

the JSP language with "simple tag handlers," which utilize a new, much simpler and

cleaner, tag extension API. This spurs the growing number of pluggable, reusable tag

libraries available, which in turn reduces the amount of code needed to write powerful

Web applications.

4


5/80

Easily write and maintain pages: The Java Server Pages Standard Tag Library

(JSTL) expression language is now integrated into JSP technology and has been

upgraded to support functions. The expression language can now be used instead of

scriptlet expressions.

Key Capabilities:

High Availability: Ensure business continuity with the highest levels of system

availability through technologies that protect your data against costly human errors

and minimize disaster recovery downtime.

Performance and Scalability: Deliver an infrastructure that can grow with your

business and has a proven record in handling today's large amounts of data and most

critical enterprise workloads.

Security: Provide a secure environment to address privacy and compliance

requirements with built-in features that protect your data against unauthorized access.

Manageability: Manage your infrastructure with automated diagnostics, tuning, and

configuration to reduce operational costs while reducing maintenance and easily

managing very large amounts of data.

Developer Productivity: Build and deploy critical business-ready applications more

quickly by improving developer productivity and reducing project life cycle times.

Tomcat server:

Apache Tomcat (formerly under the Apache Jakarta Project; Tomcat is now a top

level project) is a web container developed at the Apache Software Foundation.

Tomcat implements the servlet and the Java Server Pages (JSP) specifications from

Sun Microsystems, providing an environment for Java code to run in cooperation with

a web server. It adds tools for configuration and management but can also be

configured by editing configuration files that are normally XML-formatted. Because

Tomcat includes its own HTTP server internally, it is also considered a standalone

web server.

Environment:

Tomcat is a web server that supports servlets and JSPs. Tomcat comes with the Jasper

compiler that compiles JSPs into servlets.

5


6/80

The Tomcat servlet engine is often used in combination with an Apache web server

or other web servers. Tomcat can also function as an independent web server. Earlier

in its development, the perception existed that standalone Tomcat was only suitable

for development environments and other environments with minimal requirements for

speed and transaction handling. However, that perception no longer exists; Tomcat is

increasingly used as a standalone web server in high-traffic, high-availability

environments.

Since its developers wrote Tomcat in Java, it runs on any operating system that has a

JVM.

Features:

Tomcat 5.x (later versions)

Implements the Servlet 2.4 and JSP 2.0 specifications

Reduced garbage collection, improved performance and scalability

Native Windows and UNIX wrappers for platform integration Faster JSP

parsing

Online Help Desk (OHD) for the facilities in the campus. This is an Intranet based

application that can be accessed throughout the campus. This system can be used to

automate the workflow of service requests for the various facilities in the campus.

The list of modules incorporated with ONLINE HELP DESK FOR THE

FACILITIES IN THE CAMPUS is

1. 1. Administrator Module: The administrator will first creates the members of

organization. The administrator will check the quires and then update the status

and assigns the query to their respective facility to solve it.

In this module Administrator will

Creating user accounts:

The administrator will create the users of the organization which includes employees

and students. Each member in the organization were given username and password for

the login into their account. The username will be their email-id.

Updating the status posted by employee:

The administrator will update the status of the query by giving the description of it

whether he is approving or rejecting the query with appropriate description

Assigning the task:

The administrator In this the administrator will assign task to the employee(facility

members) with the specific description what action he has to be performed.

Viewing the profiles of the students and employees:

The administrator will view all the details of the students and employees who are the

members of the organization.

Authentication:

The administrator will provide a good authentication to the members of the

organization by providing the username and password to them and they are provided

with facility of changing their details like password, name etc this will provide a good

authentication to the members.

Maintenance of data base:

The administrator will maintain the database so that there will be no problems while

the members of the organization are performing the quires.

8/80

2. End-User Module: The End-User module contains the members of

organization like employees and students.

In this module parent will

Login:

The End-User is given a username and password by the administrator. The username

used is the Email-id and password is given by the administrator and later the users can

change the password and username if required.

Create new request:

In this the Students and the employees will post the request regarding their queries by

selecting the corresponding facility type and writing the description about the query.

View the status:

In this the Students and the employees will view the status that is updated by the

Administrator and they can know whether the admin has approved the request or

rejected the request.

Access books and softwares:

The In this will Students and the employees can have a special access to the eBook

library and softwares so that they can download and view the corresponding books

and softwares.

3. Facility module: The facility module will contain the employees who are

assigned with the corresponding facility types.

Login to system:

The facility members are just like the employees they are also registered by the

administrator and can login with the username and password given to them.

View and perform task assigned by administrator:

According to the queries of the students and employees the admin will approve or

reject them .If he had approved then he has the action has to be performed so, the

admin will assign the required task to the facility members and when the facility

members will login to their account they can view the task assigned by the

administrator and they perform them accordingly.

Update the status of student: The student will post the request to

the facility the status is updated by the corresponding employee or the facility.

Unified Modeling Language (UML)

It is a language to specifying, visualizing and constructing the artifacts of software

system as well as for business models. GRADY BOOCH, IVAR JACCOBSON and

JAMES RUMBUGH found it. The UML notation is useful for graphically depicting

Object Oriented Analysis and Object Oriented Design (OOA and OOD) modules.

The unified modeling language is a standard language for specifying,

Visualizing, Constructing and documenting the software system and its components. It

is a graphical language that provides a vocabulary and set of semantics and rules. The

UML focuses on the conceptual and physical representation of the system. It captures

the decisions and understandings about systems that must be constructed. It is used to

understand, design, configure, maintain and control information about the systems.

Visualizing:

Through UML we see or visualize an existing system and ultimately

we visualize how the system is going to be after implementation. Unless we think

we cannot implement. UML helps to visualize how the components of the system

communicate and interact with each other.

Specifying:

Specifying means building models that are precise, unambiguous and

complete UML addresses the specification of all the important Analysis Design,

Implementation decisions that must be made in developing and deploying a software

system.

Constructing:

UML models can be directly connected to a variety of programming

language through mapping a model from UML to a programming language like Java or

C++ or VB.

Forward Engineering and Reverse Engineering is possible through UML.

Documenting:

The deliverables of a project apart from coding are some artifacts

which are critical in controlling, measuring and communicating about a system during

its development viz. Requirements, Architecture, Design, Source code, Project plans,

Tests, Prototypes, Releases etc.

DIAGRAMS IN UML:

Diagrams are graphical presentation of set of elements. Diagrams project a

system, or

visualize a system from different angles and perspectives. The UML has nine

diagrams these

diagrams can be classified into the following groups:

1) Static or structural diagrams

2) Dynamic or behavioral diagrams

1) STATIC OR STRUCTURAL DIAGRAMS:

Class Diagram: This shows a set of classes, interfaces, collaborations and their

relationships. There are the most common diagrams in modeling the object oriented

systems and are used to give the static view of a system.

2) DYNAMIC OR BEHAVIORAL DIAGRAMS:

Use case Diagram: Shows a set of use cases and actors and their relationships. These

diagrams illustrate the static use case view of a system and are important in organizing

and modeling the behaviors of a system.

Sequence Diagram: Sequence diagram is an interaction diagram which focuses on the

time ordering of messages it shows a set of objects and messages exchange between

these objects. This diagram illustrates the dynamic view of a system.

Collaboration Diagram: This diagram is an interaction diagram that stresses or

emphasizes the structural organization of the objects that send and receive messages. It

shows a set of objects, links between objects and messages send and received by those

objects. There are used to illustrate the dynamic vies of a system.

6.1 Testing:

Testing is the process of detecting errors. Testing performs a very critical role for

quality assurance and for ensuring the reliability of software. The results of testing are used

later on during maintenance also.

6.2 Types of Testing

Unit Testing

6.2.1 Unit Testing

Unit testing focuses verification effort on the smallest unit of software i.e. the

module. Using the detailed design and the process specifications testing is done touncover errors within the boundary of the module. All modules must be successful in

the unit test before the start of the integration testing begins.

In this project each service can be thought of a module. There are so many

modules like Login, Admin module, customer module, Normal User,. Giving different

sets of inputs has tested each module. When developing the module as well as

finishing the development so that each module works without any error. The inputs are

validated when accepting from the user.

In this application developer tests the programs up as system. Software units in

a system are the modules and routines that are assembled and integrated to form a

specific function. Unit testing is first done on modules, independent of one another to

locate errors. This enables to detect errors. Through this error resulting from

interaction between modules initially avoided.

6.3 Integration Testing

After the unit testing we have to perform integration testing. The goal here is to

see if modules can be integrated properly, the emphasis being on testing interfaces

between modules. This testing activity can be considered as testing the design and

hence the emphasis on testing module interactions.

In this project integrating all the modules forms the main system. When

integrating all the modules I have checked whether the integration effects working of

any of the services by giving different combinations of inputs with which the two

services run perfectly before Integration.

6.4 Acceptance Testing

Acceptance Test is performed with realistic data of the client to demonstrate

that the software is working satisfactorily. Testing here is focused on external

behavior of the system; the internal logic of program is not emphasized.

In this project Network Management Of Database System I have collected

some data and tested whether project is working correctly or not.

Test cases should be selected so that the largest number of attributes of an

equivalence class is exercised at once. The testing phase is an important part of

software development. It is the process of finding errors and missing operations and

also a complete verification to determine whether the objectives are met and the user

requirements are satisfied.

8. Conclusion:

Therefore we are able to successfully reach the targets and goals of the

project.

This project provides an excellent support for the users in order to provide all

the members of organization directly interacting with the person in the

organization.

The Administrator is the whole controller of the project he can update

everything in the project.

To the extent that it overcomes the loopholes of manual system and achieve the

benefits of the computerized system. Here after deploying this application there is no need of wasting time to gather

the relevant and required information manually.

So we, conclude that our project Online Help Desk, will be found

to be most useful and also we expect a better vision for a campus in near future.

Future Scope:

The scope of the project work is not limited to developing a web server

and providing services to the client but also can be extended to

More Security:by continuing to establish a firewall at the server, protecting the client

systems from access to unauthorized or virus probed sites.

It can be enhanced to include uploading a file giving message.

It can be enhanced to include give common alerts to group of people.
