Organization overview &
Introduction:
This system “Inventory system” has been developed by Ms. AMRITA
SINGH as an academic project for the Computer Science Department of S.K.
College of Science & Commerce as a part of the T.Y. BSc Computer
Science Course.
This system was created with a lot of anticipation towards mastering the
basics of system creation .It was designed in such a way so as to help us make
use of basic technologies like Visual Studio and MS SQL .It has used the
concepts of maintaining a uniform system structure and during the process of
creating this system an honest effort has been made towards creating a
professional system in the future.

8
Description of the System:
During the past several decade’s personnel function has
been transformed from a relatively obscure record keeping staff to
central and top level management function. There are many factors
that have influenced this transformation like technological
advances, professionalism, and general recognition of human beings
as most important resources.
 A computer based management system is designed to handle the entire
primary Information required to calculate monthly statements. Separate
database is maintained to handle all the details required for the correct
statement calculation and generation.
 This project intends to introduce more user friendliness in the various
activities such as record updating, maintenance, and searching.
 The searching of record has been made quite simple as all the details of
the Book can be obtained by simply keying in the identification of those
Books.
 Similarly, record maintenance and updating can also be accomplished by
using the identification of the Book with all the details being
automatically generated. These details are also being promptly
automatically updated in the Master files thus keeping the record
absolutely up-to-date.

9
 The entire information has maintained in the database or Files and
whoever wants to retrieve can’t retrieve, only authorization user can
retrieve the necessary information which can be easily is accessible from
the file.
Limitations of the Present System:
The present system has several shortcomings that are as follows:-
 In Present system each and every record is maintains in registers, so
there will be lot of redundancy in maintain book records.
 Also there is no security due to all records are maintain in register.
 Modification of one record causes to other records related to that record,
so work becomes very critical, so some time data loss will be ocular.
 Storage of information is costly.
 Require knowledge about this system.
 More time required for reading & adding records in register
 Searching any old record of any job done or damaged required more
time due to critical system of register.

10
Proposed System:
This system computerized all the requirements of the owner. It will give the
owner the feature of maintaining all the profiles of its customer, Suppliers, the
Product in which the owner deals in, the companies of whose product the
owner sells. It gives the user the functionality of searching stock without
manually checking it as stock entries are updated throughout the sales and
purchase transaction. It also keeps track of the enquiries made in the owner by
various people.
OBJECTIVES
1) Data management.
2) Data retrieval at will.
3) Data modification.
4) Save time thereby increasing performance.
5) Reducing work process time.
6) Provide various report facility.
7) Cost effective and less manpower required.

11
Advantages of The Proposed System:
 This system uses MS SQL as data base which is strong and secure
database for proposed system.
 The proposed system empowers the user with a new computer based
system by reducing the efforts of data maintenance.
 The proposed developed according to the user specification hence it is a
user-centered system.
 This system provides a facility to generate a bill as soon as the customer
purchases a product.
 If the customer has not paid the full payment then there is a facility to
check the balance amount that has to be paid by the customer.

12
Limitation of the Proposed System :
 The system prepared is competent but we cannot say that it is a perfect
system. This system like any other system has some flaws &
shortcomings in it. They are as follows:
 This system is semi-functional. This means that the system covers the
manipulation related to the record only.
 Only one person can use the system.
 There would be high rate & better quality of performance.
System requirementsSystem requirements
Hardware and software requirements:
The least hardware requirements are:
1) Minimum 2 GB HDD space
2) Pentium or Celeron based processor

13
3) 128 MB RAM
The least software requirements are:
1) Operating system: - Windows XP, Windows7.
2) Front-end Tool: - Visual studio 2008.
3) Back-end Tool: - MS SQL Server 2005.
4) Report Generation: - Crystal Report Basic.
FEASIBILITY STUDY
Every project would be feasible, if provided with
unlimited resources and unlimited time. But unfortunately, the
development of computer-based system of book is more likely plagued
by a security of resources and difficult time constraint. It is both
necessary and prudent to evaluate the feasibility of the project at the
earliest possible time. During software engineering we concentrate our
attention on four primary area of interest. The techniques used in
conducting an initial investigation and feasibility study are very similar
but the objectives are not so.
The major objectives of feasibility study are to further define the
problem and to determine the best way to solve it. The typical primary
objectives are:

14
• A centralized database will be developed.
• Runtime operating decision-making will be eliminated.
• Unnecessary control procedure will be automated.
• The minimum of paper work should be produced.
• The output produced by the system should be in a usable format

System Analysis
STAKE HOLDERS
A corporate stake holder is a party that can affect or be affected by
the actions of the business as a whole.
TYPES OF STAKE HOLDERS:
 Internal stake holder

17
Internal stake holders-Market (or primary)Stake holders are those that
are engaged in economic transactions with the business.
 External stake holders-
Non market(or secondary) stake holders are those who although they do
not engaged in direct economic exchange with the business are
affected by or can affect its actions.
 Owner
The owner of the admission system needs to keep a check on
everything which is visiting admission system about each and every
registration and viewing and making changes i.e. update, delete etc. this is
one of the important issue to be handled . Book should be updated
regularly as if the new book comes in to avoid any mistake.
FACT FINDING TECHNIQUES:

18
The system referred is the “Inventory system” that deals with the bills
of the customer & supplier. The following are the fact-finding techniques,
which were followed:
1) Going through all the existing documentation, files, registers:
I went through all the files and registers in which the supplier’s
details were kept. I also referred the handmade bills and receipts. From
this I traced out the history, which was required for the existing system
to be implemented.
2) Research and site visit:
I visited the shop several times, which was very important for gathering the
details about the items stored in the shop and the how the bill is generated.
3) Observation:
By visiting the shop I observed how the manual process is been taking place.
Through observation I was able to see what exactly is to be done.
4) Questionnaires:
Questionnaires are the special purpose documents that allowed me to collect
information and opinions from respondents. Through questionnaires it was
possible to know the requirements of the respondent.
5) Interviews:
Through interviews it was possible for me to collect information from the
respondent face-to-face
Event Table

Use Case Diagram

21
The use case diagram is used to identify the primary elements and processes that
form the system. The primary elements are termed as "actors" and the processes are called
"use cases." The use case diagram shows which actors interact with each use case.

27
Class Diagram
The class diagram is used to refine the use case diagram and define a detailed
design of the system. The class diagram classifies the actors defined in the use case
diagram into a set of interrelated classes. The relationship or association between the
classes can be either an "is-a" or "has-a" relationship. Each class in the class diagram may
be capable of providing certain functionalities.

28
Sequence Diagram
A sequence diagram represents the interaction between different objects in the
system. The important aspect of a sequence diagram is that it is time-ordered. This means
that the exact sequence of the interactions between the objects is represented step by step.
Different objects in the sequence diagram interact with each other by passing "messages".

29
COLLABORATION DIAGRAM
A collaboration diagram, also called a communication diagram or interaction
diagram, is an illustration of the relationships and interactions among software objects in the
Unified Modeling Language.

Component Diagram
The component diagram represents the high-level parts that make up the system.
This diagram depicts, at a high level, what components form part of the system and how
they are interrelated. A component diagram depicts the components culled after the
system has undergone the development or construction phase.

33
Package Diagram
A package diagram in the Unified Modeling Language depicts
the dependencies between the packages that make up a model. Package diagrams can use
packages containing use cases to illustrate the functionality of a software system

34
Deployment Diagram
The deployment diagram captures the configuration of the runtime elements of the
application. This diagram is by far most useful when a system is built and ready to be
deployed.

35
System Flow Chart:
A systems flow chart shows the key inputs and outputs associated with the program.
The shape of the symbols indicates the types of input or output devices.

Validation

42
There are many approaches to software testing. Reviews, walkthroughs,
or inspections are considered as static testing, whereas actually executing programmed code
with a given set of test cases is referred to as dynamic testing. Static testing can be (and
unfortunately in practice often is) omitted. Dynamic testing takes place when the program
itself is used for the first time (which is generally considered the beginning of the testing
stage). Dynamic testing may begin before the program is 100% complete in order to test
particular sections of code (modules or discrete functions). Typical techniques for this are
either using stubs/drivers or execution from a debugger environment. For
example, spreadsheet programs are, by their very nature, tested to a large extent
interactively ("on the fly"), with results displayed immediately after each calculation or text
manipulation.
White box testing is when the tester has access to the internal data structures and
algorithms including the code that implement these.
Types of white box testing
The following types of white box testing exist:
 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 methods - improving the coverage of a test by introducing faults to
test code paths
Test coverage
White box testing methods can also be used to evaluate the completeness of a test suite that
was created with black box testing methods. This allows the software team to examine parts

43
of a system that are rarely tested and ensures that the most important function points have
been tested.
Two common forms of code coverage are:
 Function coverage, which reports on functions executed
 Statement coverage, which reports on the number of lines executed to complete the
test
They both return code coverage metric, measured as a percentage.

46
Test Case
The forms were tested for their functionality and error messages are displayed
wherever the input does not meet the required requirements
 Login form giving error message.
If any invalid user want to take entry into the system then this form restrict him from
entering into the system. By entering invalid username or password it gives an error
message
 Add Book Form gives an error message.
Add Book form gives an error message if valid data entry is not done. For example, Price
should be numeric.
 Update Book Form gives error message
Update Book form gives an error message if valid data entry is not done. For example, if no
book is selected then it gives an error message ‘Please select Book’.
