Description of the System The current system used by shop is basically entering data

related to the customers, manually done using registers.

All product or customer related information is filled in their

respective form or receipt copy of the same is given to the

customer too.

All the records of order product form and all reports are stored

in different registers.

This system also enables the owner to calculate profit.

After completion of project and satisfactory result project issubmitted to Client Company with completion.

Limitations of theCurrentSystem:

Lack of Data security :

Tampering of data.

Physical destruction of data.

Unauthorized access of data by other person.

Overhead of data management :

Lots of paper work.

Updating is complicated :

Difficult to rectify the data.

Wastage of time for searching required details.

Proposed System:4 | P a g e


5/101

Since existing system is manual, focus is on automating the entire

system and computerizes the handling process. So that the work

should be easy and more accurate.

Proposed System

Requirement:

To make provision for user friendly interface to enter the all

required details.

Have provision to generate various required details of

customer, product, order etc. easily with the help of Name, ID,

etc.

Maintain all updated details of products, inventory and

employees.

To produce bill slip to customer.

Advantages of Proposed

System

FEASIBILITY STUDYEvery project would be feasible, if provided with unlimited

resources and unlimited time. But unfortunately, the development

of computer-based system of product 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:

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.

UML Diagrams

descriptionsThe underlying premise of UML is that no one diagram can capture

the different elements of a system in its entirety. Hence, UML is

made up of nine diagrams that can be used to model a system at

different points of time in the software life cycle of a system. The

nine UML diagrams are:

Use case diagram: The use case diagram is used to

identify the primary elements and processes that form thesystem. 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.

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. These

functionalities provided by the class are termed "methods" of

the class. Apart from this, each class may have certain

"attributes" that uniquely identify the class.

Object diagram:The object diagram is a special kind of

class diagram. An object is an instance of a class. This

essentially means that an object represents the state of a class

at a given point of time while the system is running. The object

diagram captures the state of different classes in the system

and their relationships or associations at a given point of time.

State diagram:A state diagram, as the name suggests,

represents the different states that objects in the system

undergo during their life cycle. Objects in the system change

states in response to events. In addition to this, a state

diagram also captures the transition of the object's state from

an initial state to a final state in response to events affecting

the system.

14 | P a g e


15/101

Activity diagram:The process flows in the system are

captured in the activity diagram. Similar to a state diagram, an

activity diagram also consists of activities, actions, transitions,

initial and final states, and guard conditions.

Sequence diagram: A sequence diagram represents theinteraction 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".

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 thesystem and how they are interrelated. A component diagram

depicts the components culled after the system has undergone

the development or construction phase.

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.

Now that we have an idea of the different UML diagrams, let us seeif we can somehow group together these diagrams to enable us to

further understand how to use them.

UML Diagram Classification

Static,Dynamic, and

ImplementationA software system can be said to have two distinct characteristics: a

structural, "static" part and a behavioral, "dynamic" part. In

addition to these two characteristics, an additional characteristic

that a software system possesses is related to implementation.

Before we categorize UML diagrams into each of these three

characteristics, let us take a quick look at exactly what these

characteristics are.

Static:The static characteristic of a system is essentially

the structural aspect of the system. The static characteristics

define what parts the system is made up of.

Dynamic:The behavioral features of a system; forexample, the ways a system behaves in response to certain

events or actions are the dynamic characteristics of a system.

Implementation:The implementation characteristic of a

system is an entirely new feature that describes the differentelements required for deploying a system.

The UML diagrams that fall under each of thesecategories are:

Static

Use case diagram

Object diagram

State diagram

3 Implementation Component diagram

4+1 View of UML

DiagramsConsidering that the UML diagrams can be used in different stagesin the life cycle of a system, let us take a look at the "4+1 view" of

UML diagrams. The 4+1 view offers a different perspective to

classify and apply UML diagrams. The 4+1 view is essentially how a

system can be viewed from a software life cycle perspective. Each of

these views represents how a system can be modeled. This will

enable us to understand where exactly the UML diagrams fit in and

their applicability.

These different views are:

Design View:The design viewof a system is the structural

view of the system. This gives an idea of what a given system

is made up of. Class diagrams and object diagrams form the

design view of the system.

Process View:The dynamic behavior of a system can be

seen using theprocess view. The different diagrams such as

the state diagram, activity diagram, and sequence diagram are

used in this view.

Component View:Next, you have the component view

that shows the grouped modules of a given system modeled

using the component diagram.

Deployment View:The deployment diagram of UML is

used to identify the deployment modules for a given system.

This is the deployment viewof the

Use case View:Finally, we have the use case view. Use

case diagrams of UML are used to view a system from this

perspective as a set of discrete activities or transactions.

ValidationThere 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 ofthe application using public and private APIs

Code coverage - creating tests to satisfy some criteria of codecoverage (e.g., the test designer can create tests to cause allstatements in the program to be executed at least once)

Fault injection methods - improving the coverage of a test byintroducing faults to test code paths

37 | P a g e


38/101

Mutation testing methods

Static testing - White box testing includes all static testing

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 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 testThey both return code coverage metric, measured as a percentage.

CONCLUSIONAn attempt is made in all its earnest towards

the successful completion of the project. This system

was verified with valid as well as with invalid data.

This system is user friendly since it has been

developed in visual studio 8 a successful GUI

environment. Since the connection can be extended to

any database. The control will be more powerful.

Connecting it to any type of database extends the

development control. Any suggestions for future

development of the system are welcome

Upgrading the system if may can be done without

affecting the proper functioning of system.
