ONLINE EXAMINATION
INTRODUCTION :-
Online examinations are an important method of evaluating the success potential
of students. This research effort the individuals under consideration were students who would be
enrolling in computer courses or Technologies Registrations. A prototype of a web-based placement
examination system is described from the standpoint of the research effort, end user, and software
development.
An on-line educational system including exam processing and electronic journal
features. An instructor builds a course based questions which on-line contain in identification of
assignments. Which are compiled into an on-line exam syllabus?
Users enrolled in the platform may access the electronic details they provided and
perform various functions with the on-line educational system in order to participate in the on-line
examinations. Users can receive an on-line exam, having multimedia content, for the course, and they
can electronically provide answers for the exam. And after Completion of their duration of exam they
are provided the grade or marks secured in their examinations.

INTRODUCTION :-

Online examinations are an important method of evaluating the success potential

of students. This research effort the individuals under consideration were students who would be

enrolling in computer courses or Technologies Registrations. A prototype of a web-based placement

examination system is described from the standpoint of the research effort, end user, and software

development.

An on-line educational system including exam processing and electronic journal

features. An instructor builds a course based questions which on-line contain in identification of

assignments. Which are compiled into an on-line exam syllabus?

Users enrolled in the platform may access the electronic details they provided and

perform various functions with the on-line educational system in order to participate in the on-line

examinations. Users can receive an on-line exam, having multimedia content, for the course, and they

can electronically provide answers for the exam. And after Completion of their duration of exam they

are provided the grade or marks secured in their examinations.

INTRODUCTION:

on-line examinations contents providers

to focus on creating effective assessment questions and focusing on

exam’s feedback delivery to students. In the paper we present

techniques that are pertinent to the elements of assessment process:

answers submission, computerized grading, and feedback after

submission.

As the modern organizations are automated

and computers are working as per the instructions, it becomes

essential for the coordination of human beings, commodity and

computers in a modern organization.

The administrators ,instructor,Students who are

attending for online examination can communicate with the system

through this projects, thus facilitating effective implementation and

monitoring of various activities of Online Examinations like conducting

Exams as per scheduled basis and delivering result to that particular

use or student.And the details of students who attempted Online

Examination are maintained at administrator.

a particular exam. This application takes care of authentication of the

administrator,Instructor as well as the student.

3. Objective of the System

The objective of the Online Examination Tool is to provide better information for the

users of this system for better results for their maintainence in student examination schedule

details and grading details.

UML Diagrams:

Actor:

A coherent set of roles that users of use cases play when interacting with the use `cases.

Use case:

A description of sequence of actions, including variants, that a system performs that

yields an observable result of value of an actor.

UML stands for Unified Modeling Language. UML is a language for specifying, visualizing and

documenting the system. This is the step while developing any product after analysis. The goal

from this is to produce a model of the entities involved in the project which later need to be

built. The representation of the entities that are to be used in the product being developed

need to be designed.

There are various kinds of methods in software design:

They are as follows:  Use case Diagram  Sequence Diagram  Collaboration Diagram  Activity Diagram  State chat Diagram USECASE DIAGRAMS: Use case diagrams model behavior within a system and helps the developers understand of what the user require. The stick man represents what’s called an actor. Use case diagram can be useful for getting an overall view of the system and clarifying who can do and more importantly what they can’t do. Use case diagram consists of use cases and actors and shows the interaction between the use case and actors.  The purpose is to show the interactions between the use case and actor.  To represent the system requirements from user’s perspective.  An actor could be the end-user of the system or an external system. USECASE DIAGRAM: A Use case is a description of set of sequence of actions. Graphically it is rendered as an ellipse with solid line including only its name. Use case diagram is a behavioral diagram that shows a set of use cases and actors and their relationship. It is an association between the use cases and actors. An actor represents a real-world object. Primary Actor – Sender, Secondary ActorReceiver.

COLLABORATION DIAGRAM:

A collaboration diagram is an introduction diagram that emphasizes the structural

organization of the objects that send and receive messages. Graphically a collaboration

diagram is a collection of vertices and arcs.

CLASS DIAGRAM:

Class is nothing but a structure that contains both variables and methods. The Class

Diagram shows a set of classes, interfaces, and collaborations and their relating ships. There

is most common diagram in modeling the object oriented systems and are used to give the

static view of a system. It shows the dependency between the classes that can be used in our

system.

The interactions between the modules or classes of our projects are shown below. Each

block contains Class Name, Variables and Methods.

State Chart Diagram .

DATA FLOW DIAGRAMS :

The DFD takes an input-process-output view of a system i.e. data objects flow into the software, are transformed by processing elements, and resultant data objects flow out of the software. Data objects represented by labeled arrows and transformation are represented by circles also called as bubbles. DFD is presented in a hierarchical fashion i.e. the first data flow model represents the system as a whole. Subsequent DFD refine the context diagram (level 0 DFD), providing increasing details with each subsequent level. The DFD enables the software engineer to develop models of the information domain & functional domain at the same time. As the DFD is refined into greater levels of details, the analyst perform an implicit functional decomposition of the system. At the same time, the DFD refinement results in a corresponding refinement of the data as it moves through the process that embody the applications. A context-level DFD for the system the primary external entities produce information for use by the system and consume information generated by the system. The labeled arrow represents data objects or object hierarchy.
