Chapter 1:- Introduction
1.1 Overview
Information for tutor guardian(i-TG) system is application that tracks current student’s academic information.
It maintains academic information for ready access by office staff, their faculty advisors, and committee
members. Instead of tedious paper work, tutor guardian will be able to submit required information
electronically, and the departments will be able to evaluate the submissions with a much quicker turnaround.
Information for tutor guardian System has been modularized into following modules.
ADMINISTRATOR MODULE
In this module when the administrator will enter in to the administrator page and this page consists of
two following sub modules.
 Student Addition/ Updation / Deletion: In i-TG each Student is added, updated or deleted according to
its branch.
 Attendance/Result Generation: In i-TG information about attendance and Internal result is generated.
1.2 Project Objective :-.
 Can be used anywhere any time as it is a web based application(user location doesn’t matter).
1.3 PROJECT SCOPE:
Student Information System is a web-based application for students, faculty, academic staff and parents who
want to get and retrieve student’s whole information instantly via internet. The major benefit of this web portal
is to store the students information at one place (like SERVER) and it can be accessed via online interaction.
The i-TG web portal is to replace the old and traditional file(paper work) storing process. Instead of tedious
paper work, students will be able to submit required information electronically, and the departments will be able
to evaluate the submissions with a much quicker turnaround

2.2 Feasibility Report :-
2.2.1 Innovativeness and Usefulness :-
Technical feasibility centers on the existing manual system of the test
management process and to what extent it can support the system.
According to feasibility analysis procedure the technical feasibility of the
system is analyzed and the technical requirements such as software facilities ,input
are identified.
2.2.2Market Potential and Competitive advantages:-
Economic analysis is most frequently used for evaluation of the effectiveness of the
system. This part of feasibility study gives the top management the economic
justification for the new system. This system has a great market potential because,
if the organization implements this system, it need not require any additional
hardware resources as well as it will be saving lot of time.
DEVELOPMENT METHOD:
The following methods and approaches are used to develop this project.

Oriental Institute of science and technology Page 10
Microsoft SQL Server
A database management, or DBMS, gives the user access to their data and helps them transform the data
into information. These systems allow users to create, update and extract information from their database.
A database is a structured collection of data. Data refers to the characteristics of people, things and
events. SQL Server stores each data item in its own fields. In SQL Server, the fields relating to a particular
person, thing or event are bundled together to form a single complete unit of data, called a record (it can also be
referred to as raw or an occurrence). Each record is made up of a number of fields. No two fields in a record
can have the same field name.
 SQL Server Tables
SQL Server stores records relating to each other in a table. Different tables are created for the
various groups of information. Related tables are grouped together to form a database.
 Primary Key
Every table in SQL Server has a field or a combination of fields that uniquely identifies each record
in the table. The Unique identifier is called the Primary Key, or simply the Key. The primary key
provides the means to distinguish one record from all other in a table. It allows the user and the
database system to identify, locate and refer to one particular record in the database.
 Foreign Key
When a field is one table matches the primary key of another field is referred to as a foreign key. A
foreign key is a field or a group of fields in one table whose values match those of the primary key of
another table.
 Referential Integrity
Not only does SQL Server allow you to link multiple tables, it also maintains consistency
between them. Ensuring that the data among related tables is correctly matched is referred to as
maintaining referential integrity.
 Relational Database
Sometimes all the information of interest to a business operation can be stored in one table. SQL
Server makes it very easy to link the data in multiple tables. Matching an employee to the department in
which they work is one example. This is what makes SQL Server a relational database management
system, or RDBMS. It stores data in two or more tables and enables you to define relationships between
the table and enables you to define relationships between the tables.
 Data Abstraction

Oriental Institute of science and technology Page 11
A major purpose of a database system is to provide users with an abstract view of the data. This
system hides certain details of how the data is stored and maintained. Data abstraction is divided into
three levels.
o Physical level: This is the lowest level of abstraction at which one describes how the data are actually
stored.
o Conceptual Level: At this level of database abstraction all the attributed and what data are actually
stored is described and entries and relationship among them.
o View level: This is the highest level of abstraction at which one describes only part of the database.
Advantages of RDBMS
 Redundancy can be avoided
 Inconsistency can be eliminated
 Data can be Shared
 Standards can be enforced
 Security restrictions ca be applied
 Integrity can be maintained
 Conflicting requirements can be balanced
 Data independence can be achieved.
Disadvantages of RDBMS
A significant disadvantage of the RDBMS system is cost. In addition to the cost of purchasing of
developing the software, the hardware has to be upgraded to allow for the extensive programs and the
workspace required for their execution and storage. While centralization reduces duplication, the lack of
duplication requires that the database be adequately backed up so that in case of failure the data can be
recovered.
JAVA 1.6
The most important characteristic of Java is that it was designed from the outset to be machine
independent. We can run Java programs unchanged on any machine and operating system combination that
supports Java. Java programs are intrinsically more portable than programs written in other languages. An
application written in Java will only require a single set of source code statements, regardless of the number of
different computer platforms on which
it is run, so it is very useful for internet application.
 Platform independence - Java programs can be run on many platforms without modification. This portability is assured
by using a Virtual machine1
. When a Java program is compiled byte-code is created rather than a standard executable
file. Effectively, this is machine code for a virtual machine, which is then interpreted by the Java interpreter. The byte-
code can be run on any platform which has a suitable interpreter.
 Security - since Java has always been designed with distributed applications in mind, security has been incorporated
right from the start, and if anything this has been seen to be too restrictive.

Java and the JDK
The Java Development Kit contains all the necessary tools for the development of Java applications and
applets, including a compiler, interpreter, class libraries, applet viewer and debugger. The current version of the
JDK, 1.4.2, is freely available from Sun's web she- for machines running Windows 95, Windows NT, Solaris
SPARC and Solaris x86, and a version for the Macintosh is expected later this year (version 1,0 is currently
available). Ports to other machines may also be available from other sources. It should be noted that browsers may not
yet support applets created using features in the latest JDK.
Characteristics of Java
 Simple
 Secure
 Portable
 Object-oriented
 Robust
 Multithreaded
 Architecture-neutral
 Interpreted
 High performance
 Distributed
 Dynamic
J2EE
The Java-2 Enterprise Edition (J2EE™) provides a component-based approach to the design,
development, assembly, and deployment of enterprise applications. The J2EE platform offers a multitiered
distributed application model, reusable components, a unified security model, flexible transaction control, and
web services support through integrated data interchange on Extensible Markup Language (XML)-based open
standards and protocols.
Components of J2EE
 SERVLET
Java servlets are small, platform-independent Java programs that can be used to extend the
functionality of a Web server in a variety of ways. Servlets are to the server what applets are to the
client—small Java programs compiled to bytecode that can be loaded dynamically and that extend the
capabilities of the host. It is a server side programming language.
 JSP
Java Server Pages is the extension of servlet to simplify the programming and coding of servlet.
It includes HTML tags to make coding easy. Ultimately it convert into the servlet at the time of calling.

CHAPTER 3:- PROCESS MODEL(complete)
3.1 Proposed Process Model:-
In this project Waterfall Model is followed.
.
Fig 3.1

Oriental Institute of science and technology Page 14
This model contains 6 phases:-
 Feasibility and requirement analysis :-
Requirement gathering activity involves the analysis of the problem and
collection of the relevant information relating to the product. The main aim of
this activity is to determine whether it would be financially and technically
feasible to develop the product.
 Requirement gathering:-
The goal of this phase is to understand the exact requirements of the customer
and to document them properly.
 System Design :-
The goal of this phase is to transform the requirement specification into a
structure that is suitable for implementation in some programming language.
 Testing:-
In this phase all the modules of the software are tested.
 Deployment of System:-
In this all the modules are integrated and then deployed.
 Operation and Maintenance:-
Release of software inaugurates the operation and life cycle phase of the
operation.
The phases always occur in this order and do not overlap.

CHAPTER 7:- TESTING
 Software testing is the process of executing a program with intension of finding errors in the code.
 It is a process of evolution of system or its parts by manual or automatic means to verify that it is
satisfying specified or requirements or not.
 To purpose of system testing is to check and find out the errors or faults as early as possible so
losses due to it can be saved.
 Testing is the fundamental process of software success.
 Testing is not a distinct phase in system development life cycle but should be applicable
throughout all phases i.e. design development and maintenance phase.
 Testing is used to show incorrectness and considered to success when an error is detected.
Different levels of testing are used in the test process; each level of testing aims to test different aspects of
the system:-
The first level is unit testing. In this testing, individual components are tested to ensure that they operate
correctly.
The second level is integration testing. It is a systematic technique for constructing the program
structure. In this testing, many tested modules are combined into the subsystems which are then tested.
The good here is to see if the modules can be integrated properly.
Third level is integration testing. System testing is actually a series of different tests whose primary
purpose is to fully exercise computer based system. These tests fall outside scope of software process and
are not conducted solely by software engineers.
7.1 Testing Used:-
 White Box Testing
 Black box Testing

Oriental Institute of science and technology Page 65
7.1.1 White box testing:- White-box testing tests internal structures or workings of a program, as
opposed to the functionality exposed to the end-user. In white-box testing an internal perspective of the
system, as well as programming skills, are used to design test cases. The tester chooses inputs to exercise
paths through the code and determine the appropriate outputs.
While white-box testing can be applied at the unit, integration and system levels of the software testing
process, it is usually done at the unit level. It can test paths within a unit, paths between units during
integration, and between subsystems during a system–level test. Though this method of test design can
uncover many errors or problems, it might not detect unimplemented parts of the specification or
missing requirements.
Techniques used in white-box testing include:
 API testing (application programming interface):- testing of the application using public and
private APIs.
 Code coverage:-creating tests to satisfy some criteria of code coverage (e.g., the test designer can
create tests to cause all statements in the program to be executed at least once).
 Fault injection method:- intentionally introducing faults to gauge the efficacy of testing strategies.
 Mutation testing methods.
 Static testing method.
7.1.2 Black-Box Testing:- Black-box testing treats the software as a "black box", examining functionality
without any knowledge of internal implementation. The testers are only aware of what the software is
supposed to do, not how it does it. Black-box testing methods include: equivalence partitioning, boundary
value analysis, all-pairs testing, state transition tables, decision table testing, fuzz testing, model-based
testing, use case testing, exploratory testing and specification-based testing.
7.1.3Alpha testing:- Alpha testing is simulated or actual operational testing by potential users/customers
or an independent test team at the developers' site. Alpha testing is often employed for off-the-shelf
software as a form of internal acceptance testing, before the software goes to beta testing.

Oriental Institute of science and technology Page 66
7.1.4 Beta testing:- Beta testing comes after alpha testing and can be considered a form of external user
acceptance testing. Versions of the software, known as beta versions, are released to a limited audience
outside of the programming team. The software is released to groups of people so that further testing can
ensure the product has few faults or bugs. Sometimes, beta versions are made available to the open public
to increase the feedback field to a maximal number of future users

CHAPTER 9:- FUTURE ENHANCEMENTS(complete)
This is the version 1 of this system and in near future it will be more developed than it is now .This
software product in fewer days will get euipped with new features of providing top 10 student ,last 10
students according to their mid-sem1 marks,mid-sem2 marks,attendance and their overall acadmic
performance will also be provided to TG.We enhance our software and transform it as online software
such that any one access it from anywere.we also make a parent zone from where parent can access
details of his son/daughter.To avoid server down problems a new version will be launched which will be
fruitful to the user during the rush hours.
