INTRODUCTION
Offline examiner is a real time project and implimentation. The project and implimentation will be implemented using VB. The aim of the project and implimentation is to allow teachers to conduct examinations to the students. There are many unique features in the project and implimentation. The students are not allowed to go back to the previous question once they click the next question. This option is up to the teachers to decide the teachers can either enable such an option or disable the option. The teachers are also given option to set the time limit of the exam. When the students start their exam, after the allotted time, the exam automatically ends and a grade sheet is printed to the students. The exams can be of single choice or multiple choices and this also the teachers can make the decision.
Another important feature of the project and implimentation is that the students are not allowed to take the screen shot of the questions as a matter of security, if students try for such a malpractice an alarm is raised in the examination hall. Various types of reports can be generated both for the teachers as well as the administrators.
The software will be used by three different types of users namely
1. Students
2. Staffs
3. Administrators
The examination can be conducted in any number of systems in the same lab, so that students of the same batch can do the
Offline Examiner 2 examinations at the same time. The questions will be issued to the students as per the order of the computer i.e. questions will be randomly displayed to the students.
Some of the modules that will be used in the project and implimentation are: Teachers can add new questions to the exam paper
In this software the teachers can add questions to the question set. The questions are stored in the database. The data base is resides on the server and the terminals can access the database and conduct the exam using the stored questions. Teachers of each subject add the respected question papers with the question set number and the question number. The mark and time for each question is also set by the teachers. Teachers have to manually enter the questions.
Teachers can set the duration of the exam
The examination duration is also set by the teachers. After the specific time the answers are submitted to the database via the network and we cannot answer any questions after the submission. The duration for each exam is varied depends on the type of the examination and the type of the subject. There are timers also for control the time duration of the examination.
Students attend the exam
Students can attend the examination with the login username and the password. The username and password is given by the administrator. The authentication of the software is done using the username and password. The username and password is passing through the network to the server system and the authorization is done on that system. Each student can
attend the exam for 3 time with the given user name and password. After that they have to re-register to attend the exam.
Administrators can generate various types of reports
In this software administrator has the power to conduct the examination and he can view the various reports like the result and the list of the passed students, the list of students apply for the examination and the list of student who attend the examination etc. He can get the report of the whole examination and the percentage of mark obtained by each student. And also he can calculate number of students passed for a particular exam in a class.
Administrators can enable security settings.
Administrator has the control over the software and the entire system. Administrator can add new user (teachers) and can give user name and password. Administrator gives the username and password to the registered students and the student can login to the system only giving the username and password. The administrator give security like students cannot take the screenshots of the examination screen, cannot write exam after the specific time, cannot answer for a previous question and cannot change the already answered question. After the specified time the answers are submitted to the server automatically.
Print out of the grade sheet is issued when the student completes the exam, or when the duration is finished
After the completion of the examination the answers are submitted for further process. The answers are compared with the database and the grade for the students is calculated after result comparison. The students can view and take printouts as mark sheet or score sheets using the software. If any printer is connected with the system using software we can take the printouts and this is the official score sheets for the students.
Students can view their past exam history
Students have the advantage that they can view the history of the examination they wrote. They can then analyze the answers and thus find the errors they done. The history of the examinations are stored on the server so the administrator or the students can take the reports as hardcopy any time.
SYSTEM ANALYSIS
Introduction to System Analysis
System analysis is a process of gathering and interpreting facts, diagnosing problems and the information to recommend improvements on the system. It 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 studied to the minutest detail and analyzed. The system analyst plays the role of the interrogator and dwells deep into the working of the present system. The system is viewed as a whole and the input to the system are identified. The outputs from the organizations are
traced to the various processes. System analysis is concerned with becoming aware of the problem, identifying the relevant and decisional variables, analyzing and synthesizing the various factors and determining an optimal or at least a satisfactory solution or program of action.
A detailed study of the process must be made by various techniques like interviews, questionnaires etc. The data collected by these sources must be scrutinized to arrive to a conclusion. The conclusion is an understanding of how the system functions. This system is called the existing system. Now the existing system is subjected to close study and problem areas are identified. The designer now functions as a problem solver and tries to sort out the difficulties that the enterprise faces. The solutions are given as proposals. The proposal is then weighed with the existing system analytically and the best one is selected. The proposal is presented to the user for an endorsement by the user. The proposal is
Offline Examiner 6 reviewed on user request and suitable changes are made. This is loop that ends as soon as the user is satisfied with proposal.
Preliminary study is the process of gathering and interpreting facts, using the information for further studies on the system. Preliminary study is problem solving activity that requires intensive communication between the system users and system developers. It does various feasibility studies. In these studies a rough figure of the system activities can be obtained, from which the decision about the strategies to be followed for effective system study and analysis can be taken.
Existing System
In the existing system the exams are done only manually but in proposed system we have to computerize all the exams using this software.
¢ Lack of security of data.
¢ More man power.
¢ Time consuming.
¢ Consumes large volume of pare work.
¢ Needs manual calculations.
¢ No direct role for the higher officials.
Proposed System
The aim of proposed system is to develop a system of improved facilities. The proposed system can overcome all the limitations of the existing system. The system provides proper security and reduces the manual work.
¢ Security of data.
¢ Ensure data accuracy's.
¢ Proper control of the higher officials.
¢ Minimize manual data entry.
¢ Minimum time needed for the various processing.
¢ Greater efficiency.
¢ Better service.
¢ User friendliness and interactive.
¢ Minimum time required.
2.3. FEASIBILITY STUDY
Feasibility study is made to see if the project and implimentation on completion will serve the purpose of the organization for the amount of work, effort and the time that spend on it. Feasibility study lets the developer foresee the future of the project and implimentation and the usefulness. A feasibility study of a system proposal is according to its workability, which is the impact on the organization, ability to meet their user needs and effective use of resources. Thus when a new application is proposed it normally goes through a feasibility study before it is approved for development.
The document provide the feasibility of the project and implimentation that is being designed and lists various areas that were considered very carefully during the feasibility study of this project and implimentation such as Technical, Economic and Operational feasibilities. The following are its features:
2.3.1. TECHNICAL FEASIBILITY
The system must be evaluated from the technical point of view first. The assessment of this feasibility must be based on an outline design of the system requirement in the terms of input, output, programs and procedures. Having identified an outline system, the investigation must go
Offline Examiner 8 on to suggest the type of equipment, required method developing the system, of running the system once it has been designed.
Technical issues raised during the investigation are:
> Does the existing technology sufficient for the suggested one
> Can the system expand if developed
The project and implimentation should be developed such that the necessary functions and performance are achieved within the constraints. The project and implimentation is developed within latest technology. Through the technology may become obsolete after some period of time, due to the fact that never version of same software supports older versions, the system may still be used. So there are minimal constraints involved with this project and implimentation. The system has been developed using Java the project and implimentation is technically feasible for development.
2.3.2. ECONOMIC FEASIBILITY
The developing system must be justified by cost and benefit. Criteria to ensure that effort is concentrated on project and implimentation, which will give best, return at the earliest. One of the factors, which affect the development of a new system, is the cost it would require.
The following are some of the important financial questions asked during preliminary investigation:
> The costs conduct a full system investigation.
> The cost of the hardware and software.
> The benefits in the form of reduced costs or fewer costly errors.
Offline Examiner 9 Since the system is developed as part of project and implimentation work, there is no manual cost to spend for the proposed system. Also all the resources are already available, it give an indication of the system is economically possible for development.
2.3.3. BEHAVIORAL FEASIBILITY
This includes the following questions:
¢ Is there sufficient support for the users
¢ Will the proposed system cause harm
The project and implimentation would be beneficial because it satisfies the objectives when developed and installed. All behavioral aspects are considered carefully and conclude that the project and implimentation is behaviorally feasible.
SYSTEM DESIGN Introduction to System Design
Design is the first step into the development phase for any engineered product or system. Design is a creative process. A good design is the key to effective system. The term "design" is defined as "the process of applying various techniques and principles for the purpose of defining a process or a system in sufficient detail to permit its physical realization". It may be defined as a process of applying various techniques and principles for the purpose of defining a device, a process or a system in sufficient detail to permit its physical realization. Software design sits at
Offline Examiner l 0 the technical kernel of the software engineering process and is applied regardless of the development paradigm that is used. The system design develops the architectural detail required to build a system or product. As in the case of any systematic approach, this software too has undergone the best possible design phase fine tuning all efficiency, performance and accuracy levels. The design phase is a transition from a user oriented document to a document to the programmers or database personnel. System design goes through two phases of development: Logical and Physical Design.
Input design
The design of input focuses on controlling the amount of input required, controlling the errors, avoiding delay, avoiding extra steps and keeping the process simple. The input is designed in such a way so that it provides security and ease of use with retaining the privacy. Input Design considered the following things:
o What data should be given as input
o How the data should be arranged or coded o The dialog to guide the operating personnel in providing input. o Methods for preparing input validations and steps to follow when error occur.
OUTPUT DESIGN
A quality output is one, which meets the requirements of the end user and presents the information clearly. In output design it is determined how the information is to be displaced for immediate need and also the hard copy output. It is the most important and direct source information to the
Offline Examiner \ \ user. Efficient and intelligent output design improves the system's relationship to help user decision-making.
Designing computer output should proceed in an organized, well thought out manner; the right output must be developed while ensuring that each output element is designed so that people will find the system can use easily and effectively. When analysis design computer output, they should :
¦ Identify the specific output that is needed to meet the requirements.
¦ Select methods for presenting information.
¦ Create document, report, or other formats that contain information produced by the system.
DATABASE DESIGN
A database is an organized mechanism that has the capability of storing information through which a user can retrieve stored information in an
effective and efficient manner. The data is the purpose of any database and must be protected.
The database design is a two level process. In the first step, user requirements are gathered together and a database is designed which will meet these requirements as clearly as possible. This step is called
Offline Examiner l 2 Information Level Design and it is taken independent of any individual DBMS.
In the second step, this Information level design is transferred into a design for the specific DBMS that will be used to implement the system in question. This step is called Physical Level Design, concerned with the characteristics of the specific DBMS that will be used. A database design runs parallel with the system design. The organization of the data in the database is aimed to achieve the following two major objectives.
¢ Data Integrity
¢ Data independence
Normalization is the process of decomposing the attributes in an application, which results in a set of tables with very simple structure. The purpose of normalization is to make tables as simple as possible. Normalization is carried out in this system for the following reasons.
¢ To structure the data so that there is no repetition of data , this helps in saving.
¢ To permit simple retrieval of data in response to query and report request.
¢ To simplify the maintenance of the data through updates, insertions, deletions.
¢ To reduce the need to restructure or reorganize data which new application requirements arise.
RELATIONAL DATABASE MANAGEMENT SYSTEM (RDBMS):
A relational model represents the database as a collection of relations. Each relation resembles a table of values or file of records. In formal relational model terminology, a row is called a tuple, a column header is called an attribute and the table is called a relation. A relational database
Offline Examiner l 3 consists of a collection of tables, each of which is assigned a unique name. A row in a tale represents a set of related values.
RELATIONS, DOMAINS & ATTRIBUTES:
¢ A table is a relation. The rows in a table are called tuples. A tuple is an ordered set of n elements. Columns are referred to as attributes. Relationships have been set between every table in the database. This ensures both Referential and Entity Relationship Integrity. A domain D is a set of atomic values. A common method of specifying a domain is to specify a data type from which the data values forming the domain are drawn. It is also useful to specify a name for the domain to help in interpreting its values. Every value in a relation is atomic, that is not decomposable.
¢ RELATIONSHIPS:
¢ Table relationships are established using Key. The two main keys of prime importance are Primary Key & Foreign Key. Entity Integrity and Referential Integrity Relationships can be established with these keys.Entity Integrity enforces that no Primary Key can have null values.Referential Integrity enforces that no Primary Key can have null values.
¢ Referential Integrity for each distinct Foreign Key value, there must exist a matching Primary Key value in the same domain. Other key are Super Key and Candidate Keys.
¢ Relationships have been set between every table in the database. This ensures both Referential and Entity Relationship Integrity.
NORMALIZATION:
As the name implies, it denoted putting things in the normal form. The application developer via normalization tries to achieve a sensible organization of data into proper tables and columns and where names can be easily correlated to the data by the user. Normalization eliminates repeating groups at data and thereby avoids data redundancy which proves to be a great burden on the computer resources. These includes:
Normalize the data.
Choose proper names for the tables and columns.
Choose the proper name for the data.
First Normal Form:
The First Normal Form states that the domain of an attribute must include only atomic values and that the value of any attribute in a tuple must be a single value from the domain of that attribute. In other words INF disallows "relations within relations" or "relations as attribute values within tuples". The only attribute values permitted by INF are single atomic or indivisible values.
The first step is to put the data into First Normal Form. This can be donor by moving data into separate tables where the data is of similar type
in each table. Each table is given a Primary Key or Foreign Key as per requirement of the project and implimentation. In this we form new relations for each nonatomic attribute or nested relation. This eliminated repeating groups of data.
Offline Examiner l 5 A relation is said to be in first normal form if only if it satisfies the constraints that contain the primary key only.
Second Normal Form:
According to Second Normal Form, For relations where primary key contains multiple attributes, no nonkey attribute should be functionally dependent on a part of the primary key.
In this we decompose and setup a new relation for each partial key with its dependent attributes. Make sure to keep a relation with the original primary key and any attributes that are fully functionally dependent on it. This step helps in taking out data that is only dependant on apart of the key.
A relation is said to be in second normal form if and only if it satisfies all the first normal form conditions for the primary key and every non-primary key attributes of the relation is fully dependent on its primary key alone.
Third Normal Form:
According to Third Normal Form, Relation should not have a nonkey attribute functionally determined by another nonkey attribute or by a set of
nonkey attributes. That is, there should be no transitive dependency on the primary key.
In this we decompose and set up relation that includes the nonkey attributes that functionally determines other nonkey attributes. This step is
Offline Examiner l 6 taken to get rid of anything that does not depend entirely on the Primary
Key.
A relation is said to be in third normal form if only if it is in second normal form and more over the non key attributes of the relation should not be depend on other non key attribute.

MARK EVALUATION

INTRODUCTION

Objective & Scope of the project and implimentation:


Objective:

In the ONLINE EXAMINATION, Student may register them for particular course. They can use this Examination process sitting at College Campus. Student may register on or before date and time that managed by the Institutes.

This Windows Application provides facility to conduct online examination at college campus.

It saves time as it allows number of students to give the exam at a time and displays the results as the test gets over, so no need to wait for the result. It is automatically generated by the server.

Administrator has a privilege to create, modify and delete the test papers and its particular questions.

User can register, login and give the test with his specific id, and can see the results as well.
Exam can be done at any time by using LAN in College. By doing this online, Student and institutes management can save their time. Student can also collect other information related to the institute on the given Project by this project and implimentation.

There are two types of people who participate in this system one is the user and other is the administrator. The administrator is responsible for writing and scoring examinations. He can add question to the database, add new user to the database and issue a valid ID for that user. The examinee takes up the test and gets the result immediately for each section.



Scope:

 This can be used in educational institutions as well as in corporate World.

 This can be used anywhere any time as it is a windows based application (user Location doesn’t matter).
 There is no restriction that examiner has to be present when the candidate takes the test.
 It fulfils all an office application automatically with minimal overhead.



Definition of problem

In the current Examination System of ECA, Student may face several problems for Examination the courses offer by ECA. Problem like, Student may registered the course within the fixed Date and Time that can be mention by the ECA administration, behind this the problem is that, Student that are living far away will face difficulty to reach the campus for Examination on given Date and Time due to there works or a certain problems. And because of this they register the course out off date and time, and then they have to pay fine for late Examination.
When power failure or any system interruption occurs than student give exam from starting, that means student’s time wasted.




System Analysis &Design vis-à-vis user requirements


An Online Examination application will enable students to use the COLLEGE LAN to online Examination for Exam in the Institute.

The Online Examination application will have the following functionalities:

I. The application will enable a user to Exam.
II. The application will enable a student of the Institute to register to use the application.
III. The application will enable registered members can not re-Examination after entering their Examination details.
IV. The application will enable to view Examination details to the administrator.
V. The registered user can not be able to modify any personal details such as address or phone number after Examination.
VI. The application will also provide the facility to download form to Examination via post.
Following are the modules of Online Exam software:
