2. INTRODUCTION
2.1 PROBLEM DEFINITION :
Student Mark Analysis system is used for the Students and
the faculty to have an easy access for viewing the marks. It also makes the work
simpler. Here in this the students can only view the marks if their Username and the
Password are correct. They do not have the permission to change or update the marks. It
is only the faculty who can update and view the students mark. It is also the duty of the
faculty to generate the report card, to distribute the report cards and he/she can view the
report cards. All these processes are done efficiently and easily in this Student
Mark Analysis System.
This system consists of modules like
Student details
Staff details

3.2 SOFTWARE SPECIFICATION
FRONT END
: VISUAL BASIC 6.0
BACK END
: MS ACCESS
OPERATING SYSTEM : WINDOWS XP
4. SOFTWARE DESCRIPTION
4.1 ABOUT VISUAL BASIC:
Visual Basic being powerful graphical client / server application development tool
is more users – friendly and enhances the power of database management system. This
front – end has the capability of connecting and retrieving data from multiple databases. It
can access data from most databases irrespective of where the data is stored. This is
possible because Visual Basic communicates with Microsoft Access.
Users find it easy to work with application developed in visual basic since it is
Graphical User Interface. The input and output designing can be made more attractive.
Visual basic provides facility for mouse move events and timer events.
The Visual Basic is a very open environment that supports the clients / server
architecture, ActiveX, Component Object Model (COM), and Distributed Component
Object Model (DCOM). It also supports Open Database Connectivity (ODBC). The
client / server processing method have been used to communicate between the systems.
Client / Server programming
Client / server systems have evolved in conjunction with advances in desktop
computing; new storage technologies, improved network communication and enhanced
database technology.
A network of terminals called a client that is communication over a network with a
file server having a disk on which all the files are stored. The client is usually the “frontend” processor that is operated by the end user.
The server “back-end” provides data to a client, but at times the server may need
to perform some processing to produce the required data. Usually, the severs are the
containers of data. As with client, the processes that are best suited and most economical
for the server should be placed on in.
Guidelines to use a Visual Basic application:
Create the user interface: You can create an interface by inserting controls and objects
on the form. In order to make the program easier to read and debug, assign appropriate
names to the objects.
Set the properties of user interface elements: After adding objects to a form, you need
to set the objects properties.
Write code for events: After setting the initial properties form and each object, you
need to add code that executes in response to events. Events are actions performed on the
controls used. For example, click is an event that can be performed for a command.
Save the project: After the project has been created, you can save it using the save
project as menu item on the file menu option. Saving a project also saves its forms and
code modules
Test and debug the application: The run tool on the toolbar can be used to run the
project that has been created. You can also use the debugging tools to check for errors
and modify the code.
The different properties of visual basic are:
Label box:
Label controls are used to place static text on a form, it is used for labeling
purpose.
Text box:
A text box control is used for entering and editing text. It can be either single or
multi-line.
Command button:
It is one of the most used controls. It performs event-triggered programming.
Code window:
This is our basic code area. Double clicking on the form or object will bring up the
code window.
Debug window:
This allows us to run individual commands immediately by typing in the
command and pressing the enter key.
Event handler:
Windows define a number of events that visual basic supports, including click,
double click, mouse move, key press. We can write code to handle any of these events
using event handlers.
Form:
A form window or dialog box created in visual basic.
Project explorer window:
A project file is a special file that tells visual basic which forms, modules and
custom control files associated with that file.
Properties window:
Window containing the properties of a form or control object. With the exception
of those properties that can only be set at run time, we can use this window to set the
values for others.
Exe file creation:
An executable file runs without invoking visual basic and the speed of execution is
very high
Data report:
It is one of the tools for generating reports in visual basic. It is used to create eyecapturing reports. Data environment is used for connecting the database and data layout is
used for designing reports based on the users’ choice.
4.2 ABOUT MS ACCESS :-
Access is called the backend because it supports all the program modules and
utilities co-ordinate all the communication between user and the data in the database.
Access allows conditional retrieval and manipulation of data, creation and detection of
tables.
Create a wide variety of both stand alone tables and databases that link many
tables together.
Add to and edit one database by simply filling in the blank on one computer
screen.
Search for and display information in an almost endless variety of ways, then print
out the results.
Generate printed reports.
Automatically performs mathematical calculations on numerical data in our
database.
Helps in creating tables with primary keys.
Helps in designing forms.
It acts as a backend for number GUIs
Features of Access Includes:
Windows based application.
Large data management capacity.
Importing, exporting and linking external files.
Wizards and builders.
Built-in wizards.
It supports GUI and SQL.
Faster than other database packages beyond comparison.
5. SYSTEM ANALYSIS
5.1 EXISTING SYSTEM
At present all the activities are done manually. Manually using the system, whole
providing economy, flexibility and adaptability at low data becomes more complex when
the volume of the data increases. In this method of details are stored in files .
When the firm expands in the size of function a stage will be reached where
manual processing becomes inadequate and inefficient.
Drawbacks of existing system:
Physical volume of the data is very large.
Delay in information search and retrieval.
Problems of updating and backup.
Damage of papers.
The student details in separate records are tedious task. Referring to all these records and
updating is needed. There is a chance for more manual errors.
5.2 PROPOSED SYSTEM
This By developing the system we can attain the following facilities.
Easy to handle and feasible
Cost reduction.
Fast and convenient.
Advantages of the proposed system:
Eliminating of redundancy of data.
Faster data retrieval.
Build in security features.
Unique paper work.
Centralized database.
Reports
User friendly
Ease of access
6. PROJECT DESCRIPTION
The project title ““STUDENT MARK ANALYSIS
SYSTEM”.
This project Consists of Mainly two modules namely.
Student details
Staff details
6.1 Student Details:
When the authorised student enters the system using his credentials he can read
only his mark details rather can’t change them.
6.2Staff:
In this module we maintain the data like Username and Password. In this
Module, the staff are enter into the student details. The staff can perform following
operations in student mark analysis system.
LOAD GRADES:
The Load Grades allows us to load the updated grade to the Report card.
VIEW GRADES:
This module allows the faculties as well as the Students to view the Grades, Marks, Total
and the Average Marks obtained by the Student. This is the only module that can be
accessed by the Student when the User id and the User name Matches.
SAVE GRADES:
Save Grades is used to save the grade that has been allotted to Students.
UPDATE GRADES:
This module allows the faculty to update grades and then to update the
marks of the students whenever the semester of the examination results are released.
ADD STUDENT:
The staff can add new student details .
Reports
In this system, we can have the following report
Student mark details.

8. IMPLEMENTATION
Implementation is the process of converting a new or revised system design into
an operational one. It is the key stage in achieving a successful new system because
usually it involves a lot of upheaval in the user department. It must therefore be carefully
planned and controlled, apart from planning the two major tasks of preparing for
implementation are education and training of users and testing of the system. Education
of user should really have taken place much earlier in the project, when they were being
involved in the investigation and design work, training has to be given to the staff
regarding the new system once the staff has been trained the system can be successfully
implemented.
9. TESTING
Software testing is a crucial element of software quality assurance and represents
the unlimited review of specification, design and code. Testing represents an interesting
anomaly for the software. During earlier definition and development phases, it was
attempted to build software from an abstract concept to a tangible implementation. The
testing phase is responsible for ensuring that the system performs that way that the
detailed design document specifies. Testing involves testing of developed system using
various data.
Thus a series of tests were performed for the proposed system before the system was
ready for implementation. The various types of testing done on the system are:
Unit testing
System testing
Validation testing
Output testing
White box testing
Black box testing
9.1 Unit Testing:
Unit testing focuses verification effort on the smallest unit of software design,
module. This testing was carried out during the coding itself. In this testing step, each
module is found to be working satisfactory as per the expected output from the module.
9.2 System testing:
The next level of testing is system testing where the system analysts tests all the
components to see that they interact correctly when combined as a system. A series of
testing are performed for the newly developed system before the system is ready for user
acceptance testing.
9.3 Output testing:
The output generated by the system under consideration is in the format
required by the user and the information in the reports accurate.
9.4 White Box testing:
White Box testing is test case design method that uses the control structure of the
procedural design to derive test cases. Using white box testing methods,
Guarantee that all independent paths within a module have been exercised at least
once.
Exercise all the logical decisions on their true and false sides.
Execute all loops at their boundaries and within their operational bounds
Exercise internal data structures to ensure their validity.
9.5 Black Box testing:
Black box testing methods focus on the functional requirements if the software.
That is, black box testing enables us to derive sets of input conditions that will fully
exercise all functional requirements of the program.

12. CONCLUSION
Thus the application on student mark list analysis system is developed using
rational rose and implemented using visual basic. The main aspects that are behind this
application is that they enabled us to bring out the new ideas that sustained within us for
many days. This application enables the student to retrieve their student details and mark
details at anywhere with a system.
