INTRODUCTION

Student Result Analysis System is software which is helpful for students as well as the college authorities. In the current system all the activities are done manually.

It is very time consuming and costly. Our Student Result Analysis System deals with the various activities related to the students. During analysis, data

collected on the various files, decision points and transactions handled by the present system. The commonly used tools in the system are Data Flow Diagram, interviews, etc.

In the Software we can register as a user and user has of three types,

student, admin and manager. Admin has the power to add new user and can

edit and delete a user. A student can register as user and can use visible for

mark list and attendance his profile. The admin can add edit and delete marks

for the student. All the users can see the marks. The manager can add and

delete new student and staff performance,

EXISTING SYSTEM

Student Result Analysis System is software which is helpful for students as well as the college authorities. In the current system all the activities are done manually.

In the Software we can register as a user and user has of three types,

student, admin and Teacher. Admin has the power to add new user and can edit

and delete a user. A student can register as user and can use visible for mark list

and attendance his profile. The admin can add edit and delete marks for the

student. All the users can see the marks. The Teacher can add and delete new

student and staff performance,

Sometimes, these records may get misplaced or destroyed due

to some reason, in such cases problems arise when reference to those records

are required. The manual data entry on paper forms and maintenance of not as

efficient as it is required to be. Thus, it contradicts the concept of paperless

DRAWBACK OF EXISTING SYSTEM

1. The present system requires lot of manpower and there may be a delay for some work in case of absence/ shortage of Teachers.

2. The organization may lose their data because of- i. Ignorance of Teacher towards their responsibility.

ii. Misplacement of register.

iii. Lack of Care.iv. Wrong data entry in register.v. Inconvenience of maintenance of registers or records. (storage

space).

3. College may face problem in case of reassignment some Student.

4. Teacher may add wrong marks.

5. In case of forms having particular format, College may find problem to take Xerox again and again,

NEED FOR COMPUTERIZATION

The migration from a traditional (manual) system of working to a modern system by using computer wherever possible is known as computerization.

With computerization Student Result analysis will have the following

Advantage:

1. Accuracy, Automation.2. Much more detail of customer can be recorded in little time.3. Information on fingerprint detail like service provided and bill for

individual customer can be maintained.4. G.U.I. & user friendly environment.5. Searching and sorting of any record can be done.6. Very easily very quickly without any hassle7. Information of all kinds is kept much more secured. Unauthorized

personnel are prohibited from accessing any data for reading or modifying.

8. It helps in maintain a paperless office. Paper is merely used for banking up of customer record.

9. To avoid redundancy.

Monitor : 15 VGA Colour..

Ram : 1 GB.

SOFTWARE REQUIREMENTS:

Operating system : Windows XP. Windows 7, Windows 8

SYSTEM ANALYSIS

EXISTING SYSTEM:

System Analysis is a detailed study of the various operations performed by a

system and their relationships within and outside of the system. Here the key

question is- what all problems exist in the present system? What must be done to

solve the problem? Analysis begins when a user or manager begins a study of the

program using existing system.

During analysis, data collected on the various files, decision points and

transactions handled by the present system. The commonly used tools in the system

are Data Flow Diagram, interviews, etc. Training, experience and common sense are

required for collection of relevant information needed to develop the system. The

success of the system depends largely on how clearly the problem is defined,

thoroughly investigated and properly carried out through the choice of solution. A

good analysis model should provide not only the mechanisms of problem

understanding but also the frame work of the solution. Thus it should be studied

thoroughly by collecting data about the system. Then the proposed system should be

analyzed thoroughly in accordance with the needs.

System analysis can be categorized into four parts.

System planning and initial investigation

Information Gathering

Applying analysis tools for structured analysis

Feasibility study

Cost/ Benefit analysis.

In the current system we need to keep a number of records related to the

student and want to enter the details of the student and the marks manually. In this

system only the teacher or the school authority views the mark of the student and

they want to enter the details of the student. This is time consuming and has much

cost.

PROPOSED SYSTEM:

In our proposed system we have the provision for adding the details of the

students by themselves. So the overhead of the college authorities and the teachers is

become less. Another advantage of the system is that it is very easy to edit the

details of the student and delete a student when it found unnecessary. The marks of

the student are added in the database and so students can also view the marks

whenever they want.

Our proposed system has several advantages

User friendly interface

Fast access to database

Less error

More Storage Capacity

Search facility

Look and Feel Environment

Quick transaction

All the manual difficulties in managing the student details in a college

have been rectified by implementing computerization.

FEASIBILITY ANALYSIS

Whatever we think need not be feasible .It is wise to think about the

feasibility of any problem we undertake. Feasibility is the study of impact, which

happens in the organization by the development of a system. The impact can be

either positive or negative. When the positives nominate the negatives, then the

system is considered feasible. Here the feasibility study can be performed in two

ways such as technical feasibility and Economical Feasibility.

Technical Feasibility:

We can strongly says that it is technically feasible, since there will not be much

difficulty in getting required resources for the development and maintaining the

system as well. All the resources needed for the development of the software as well

as the maintenance of the same is available in the organization here we are utilizing

the resources which are available already.

Economical Feasibility

Development of this application is highly economically feasible .The

organization needed not spend much money for the development of t he system

already available. The only thing is to be done is making an environment for the

development with an effective supervision. I f we are doing so, we can attain the

maximum usability of the corresponding resources .Even after the development, the

organization will not be in condition to invest more in the organization. Therefore,

the system is economically feasible.

TESTING PROCEDURE

Test program includes of providing the program with a set o test

inputs (test cases) & observing that programs behaves as expected or not. If the

programs fails to behave as expected, then the condition under which the

failure occur are added for debugging and correction. Following are some

commonly used terms associated with testing:

1) Failure:

This condition includes presence of an error or defect or bug. They

were presence of error does not necessarily leads to failure.

2) Fault: It is incorrect intermediate stage that may have been entered during

program execution. For e.g.: unexpected change in the value of variable. A

fault may of May or may not lead to failure.

3) Test case:

It is a triplet (I, S, O) where I is data input; S is a state of system at

which data is inputted. & O is expected output of the system.

4) Test suit: It is a set of all test cases with which a given software product is

tested

TYPES OF TESTING:

Following are the major types of testing:

1) Unit testing.

2) Integration testing.

3) System testing.

4) Black box testing.

5) White box testing.

1) UNIT TESTING:

Unit testing is the testing of different modules of system in

isolation. The reason why unit testing modules of a system in isolation. The

reason why unit testing is necessary is that the other modules. With which this

module needs to be interface may not be ready. Also it is always good to test

the module in isolation because debugging. (Removal of errors in independent

module is faster than integrated system) In order to test single module we

need the complete environment for its execution. Testing a module is giving a

desired result or not. If the module with asset of inputs and observing that the

module is gaining a desired result or not. If the module fails for giving the

desired result then the condition under which failure occur is noted or

debugging & correction. This is called as unit testing.

2) INTEGRATION TESTING:

During integration testing different module of the system are integrate

using integration plan specific the steps and order in which modules are

combined to realize the full system, after each integration step the partly

integrated system is tested. The primary objective of integration testing is to

test module interface. There are different approaches of integrated testing.

a) Bio-bang approach.

b) Top –Down approach.

c) Bottom-Up approach.

d) Mixed approach.

a) Bio-bang integration testing:

It is simplest approach to integration testing where all the

modules are integrated in a single step. In simple words all the modules are

simply put together and tested.

b) Top-Down approach:

Top-Down integration testing starts with the main routine i.e. the

root modules & one or two sub-ordinate routines in the system. The top-down

integration testing approach requires the use of program to simulate the effect

of lower level routines that are called by the routines under test.

c) Bottom-up approach:

In this testing each sub system is tested separately and then full

system is tested. A subsystem may consist of many modules which

communicate among each other through well-defined interfaces.

d) Mixed integration testing:

A mixed (sandwiches) integration testing focuses on both top- down

and bottom-up approach. In top-down approach testing starts only after top

level module have been coded & unit tested. Similarly bottom-up testing can

start only after bottom level modules are ready. The mixed approach overcame

the shortcomings of both top-down & bottom up approach as testing can start

when module becomes available. Therefore this is one of the most commonly

used approaches to perform integration testing.

3) SYSTEM TESTING:

Software may consist of other system elements hardware,

information, people etc. at the end of development system integration and

validation. Tests are conducted. These tests are not conducted by the software

engineers however the step is taken during design & testing can improve the

probability of successful system integration testing. System testing is a series

of different tests whose aim is to ensure that the

System elements are properly integrated and they type are performing the

allocated function properly. There are different types of system testing

available software based system as follows:

A) Recovery testing:

Many computer based system are having a facility to recover faults

within specified time. In some cases we require system which is fault tolerant

i.e. the fault should not becomes the cause of overall system failure. In other

cases a system failure must be corrected within specified time.

Recovery testing is a system is a test that forces the software to become

fail in variety of ways verifies hat recovery is properly performed or not. It

recovery is performed by the system itself then check-pointing mechanism,

data recovery, restart activities are performed. If a system requires human

interface then mean time to repair (MTPR) activity is performed.

B) Security testing:

Any computer based system that manager sensitive information may

causes harmful action due to improper or illegal penetration. Penetration

includes variety of activities like hackers who attempt to penetrate a system,

Employer who attempts to penetrate a system for revenge etc.

Security testing is performed to verity that protection mechanism built into

system will protect from improper penetration or not.

During security testing tester attempts to penetrate the system in variety of

ways he may try to access the password, or he may attack the system to break

any defenses which is constructed into system, or be may corrupt the system,

he may brows insecure data, he may try to find key of data entry etc.

c) Stress testing:

Stress testing is executed in such a way that tester can demand

resources in abnormal way.

For example:-

i. A special test may be designed hat generate to interrupts per records

when ½ is the average rate.

ii. Input data rate can be increased by a magnitude to determine how input

functional will respond.

iii. Test career that requires maximum memory etc. a variation of stress

testing is a technique called sensitive testing. It is performed to uncover

improper processing

D) Performance testing:

For real time 7 embedded system software that performs required

function, but performance testing is necessary because in embedded system

software, required function & the performance both are importance

factors. Performance testing is design to test performance of software within a

particular time.

Performance test are often carried out along with stress testing &

usually requires both hardware & software elements

5) BLACK BOX TESTING:

In black box testing test career are form an examination of input &

output value n this testing knowledge of design code is not required.

Following are the two main approaches in black box testing.

a) Equivalence class partitioning.

b) Boundary value analysis.

a) Equivalence class partitioning:

In this approach input velour to program is portioned into a set

of equivalence class. The main idea of defining the equivalence is that

belonging to an equivalence class is good test in the software withall

values belonging to that equivalence class. Following are the general.

If the input data velour to system can specify by a range of velour, them one valid & two invalid equivalence class is generated.

If data assumes values from a set of discrete members then on

equivalence class of valid input values & other for invalid input should be

generated. For e.g.: a software that computers a square root of any integer

]which can takes values from i-5000 then there are 3 equivalence set

of integer from i-5000 & set of integer larger than 5000.

b) Boundary value analysis:

Some typical programming errors occur at the boundaries, of

different equivalent classer of input. The reason for such a error might

be due to some specific velour a programmer often fail to see the special

processing required by the input values that lies at boundary of different

equivalence.

Boundary value analysis is due to selection of test career of

boundaries of different equivalent class.

For example:-

For a function that computer the square root of integer values in

range i-5000 then the test care must include following

values {0, 1, 5000, and 5001}

5) WHITE BOX TESTING:

There are several white box testing methodologies used.

Each testing strategy is based on some Conclusions. One white box

testing may be stronger that other or may be equivalent i.e. errors are

uncovered by start egg. ‘A’ may be more than strategy ‘B’

When two testing strategies data errors that are different then

they are called are complementary testing strategies.

Various testing strategies come under white box testing is are

Follows

a) Statement coverage.

b) Branch coverage.

c) Condition coverage.

a) Statement coverage:

The statement coverage methodology aims to design test care

so art to force the execution of every statement. In a program at learn

once the main idea behind this strategy is that unless we execute a

statement. We cannot determine error in that statement. On the other

hand we also unable to determine whether the statement works

properly for all input velour or not

b) Branch coverage:

In branch coverage testing strategy the test career are designed to

make each branch condition true & false in terms. This is because each edge of

program control traversed at learns once. It is better testing strategy that

statement based testing strategy.

C) Condition coverage:

It is a structural testing in which test cares are designed

such that each component of conditional expression is give for e.. in a

conditional values. ((c1 and c2) or c3), (c1, c2 and c3) are executed

altered on according to true or false values. The condition coverage

based testing practical only if numbers of condition are small. For each

composite conditional expression all the elements must be tested

individually.

CONCLUSION

When this system was implemented, it was very difficult to make

Them used to this totally computerized system as they were habitual to traditional system of manually doing everything.

When the system was implemented, the user’s satisfaction was the

first priority.

The system was fully successful when it started to generate accurate

reports.

This system has tried its best to reduce its physical efforts of the user

and satisfy them.

In generation facilities of the system, the chances for wrong data entry have been totally eliminated.

SYSTEM LIMITATIONS

The system required the user who has a very good knowledge of

Computer, so any common user cannot work this system.

The system requires minimum windows operating system

98/2000/XP, Minimum 128 MB RAM, visual basic 6.0 studio, p-4

processor.

This system should be provided with advanced booking & online booking.

ENHANCEMENT

1. Using this software we can manage the details of the user these details will be store in the database and we can retrieve it any time as per the requirements by using this we can save our time and we can manage bulk of data.

2. As the environment is turning over the computerized system so this is the best implementation for any multiplex.

3. Using this we can share the data with many employee on our multiplex. And we can make the soft copy as well a s hard copy to maintain the data.
