2.SYSTEM ANALYSIS
2.1.EXISTING SYSTEM
The existing system for the ATM machine project operates in real-time, facilitating efficient
transactions for users. It encompasses various components, including hardware such as card
readers, pin pads, and cash dispensers, as well as software systems for account verification,
transaction processing, and network communication. Users interact with the system through
intuitive interfaces, enabling them to perform tasks such as withdrawing cash, checking balances,
and transferring funds seamlessly. The system incorporates robust security measures, including
encryption protocols and authentication mechanisms, to safeguard sensitive user information and
prevent unauthorized access. Regular maintenance and updates ensure the system's reliability and
compliance with evolving security standards, ensuring a smooth and secure banking
experience for customers.

present a picture identification. Rather, the person must only insert a bank card and enter a
personal identification number. ...
❖ Inability To Perform Complex Transactions ATMs can only perform relatively basic
transactions. ...
❖ Fees With the advent of ATMs came ATM fees. ...
❖ Privacy ...

❖ Difficulty of Use.

2.2. PROPOSED SYSTEM

4.3. UML DIAGRAMS

UML stands for Unified Modelling Language. UML is a standardized general-purpose

modelling language in the field of object-oriented software engineering. The standard is managed,
and was created by, the Object Management Group. The goal is for UML to become a common
language for creating models of object-oriented computer software. In its current form UML is
comprised of two major components: a Metamodel and a notation. In the future, some form of method
or process may also be added to; or associated with,

The Unified Modelling Language is a standard language for specifying, Visualization,

Constructing and documenting the artefacts of software system, as well as for business modelling
and other non-software systems. The UML represents a collection of best engineering practices that
have proven successful in the modelling of large and complex systems. The UML is a very important
part of developing objects-oriented software and the software development process. The UML uses
mostly graphical notations to express the design of software projects.

13
GOALS

The Primary goals in the design of the UML are as follows:

Be independent of programming languages and development process.

Provide a formal basis for understanding the modelling language.
Support higher level development concepts such as collaborations, frameworks, patterns and
components.
Integrate best practices.
Provide users a ready-to-use, expressive visual modelling language so that they can develop
and exchange meaningful models.
Provide extendibility and specialization mechanisms to extend the core concepts.

14
4.4. USE CASE DIAGRAM
A use case diagram in the Unified Modelling Language (UML) is a type of behavioural
diagram defined by and created from a Use-case analysis. Its purpose is to present a graphical
overview of the functionality provided by a system in terms of actors, their goals (represented as use
cases), and any dependencies between those use cases. The main purpose of a use case diagram is to
show what system functions are performed for which actor. Roles of the actors in the system can be
depicted.

Fig: 4.4. Use case diagram

15
4.5. CLASS DIAGRAM

Fig: 4.5. Class diagram

In software engineering, a class diagram in the Unified Modelling Language (UML) is a type
of static structure diagram that describes the structure of a system by showing the system's classes,
their attributes, operations (or methods), and the relationships among the classes. It explains which
class contains information.

16
4.6. SEQUENENCE DIAGRAM
A sequence diagram in Unified Modelling Language (UML) is a kind of interaction diagram
that shows how processes operate with one another and in what order. It is a construct of a Message
Sequence Chart
Sequence diagrams are sometimes called event diagrams, event scenarios, and timing diagrams.

Fig: 4.6. Sequence diagram

17
4.7. ACTIVITY DIAGRAM

Activity diagrams are graphical representations of workflows of stepwise activities and actions with
support for choice, iteration and concurrency. In the Unified Modelling Language, activity diagrams can be
used to describe the busine ss and operational step-by-step workflows of components in a system. An activity
diagram shows the overall flow of control.

5. SYSTEM STUDY

5.1. FEASIBILITY STUDY

The feasibility of the project is analyzed in this phase and business proposal is put forth with
a Very general plan for the project and some cost estimates. During system analysis the feasibility
study of the proposed system is to be carried out. This is to ensure that the proposed system is not a
burden to the company.
For feasibility analysis, some understanding of the major requirements for the system is essential.
Three key considerations involved in the feasibility analysis are
ECONOMICAL FEASIBILITY
TECHNICAL FEASIBILITY
SOCIAL FEASIBILITY

5.1.1. ECONOMICAL FEASIBILITY

This study is carried out to check the economic impact that the system will have on the
organization.The amount of fund that the company can pour into the research and development of
the system is limited. The expenditures must be justified. Thus, the developed system as well within
the budget and this was achieved because most ofthe technologies used are freely available. Only
the customized products had to be purchased.

5.1.2. TECHNICAL FEASIBILITY

This study is carried out to check the technical feasibility, that is, the technical requirements
of the system. Any system developed must not have a high demand on the available technical
resources. This will lead to high demands on the available technical resources. This will lead to high
demands being placed on the client. The developed system must have a modest requirement, as only
minimal or null changes are required for implementing this system.

5.1.3. SOCIAL FEASIBILITY

His level The aspect of study is to check the level of acceptance of the system by the user. This
includes the process of training the user to use the system efficiently. The user must not feel
threatened by the system, instead must accept it as a necessity The level of acceptance by the users
solely depends on the methods that are employed to educate the user about the system and to make
him familiar with it.

19
6. SYSTEM TESTING
The purpose of testing is to discover errors. Testing is the process of trying to discover every
conceivable fault or weakness in a work product. It provides a way to check the functionality of
components, sub-assemblies, assemblies and/or a finished product It is the process of exercising
software with the intent of ensuring that the

Software system meets its requirements and user expectations and does not fail in an
unacceptable manner. There are various types oftests. Each test type addresses a specific testing
requirement.

6.1. TYPES OF TESTS

6.1.1. UNIT TESTING

Unit testing involves the design oftest cases that validate that the internal program logic is
functioning properly, and that program inputs produce valid outputs. All decision branches and
internal code flow should be validated. It is the testing of individual software units of the application
.it is done after the completion of an individual unit before integration. This is a structural testing,
that relies on knowledge of its construction and is invasive. Unit tests perform basic tests at
component level and test a specific business process, application, and/or system configuration. Unit
tests ensure that each unique path of a business process performs accurately to the documented
specifications and contains clearly defined inputs and expected results.

6.1.2. INTEGRATION TESTING

Integration tests are designed to test integrated software components to determine if they
actually run as one program Testing is event driven and is more concerned with the basic outcome of
screens or fields. Integration tests demonstrate that although the components were individually
satisfaction, as shown by successfully unit testing, the combination of components is correct and
consistent. Integration testing is specifically aimed at exposing the problems that arise from the
combination of components.

6.1.3. FUNCTIONAL TESTING

Functional tests provide systematic demonstrations that functions tested are available as
specified by the business and technical requirements, system documentation, and user
manuals.Functional testing is centered on the following items:

20
Valid Input . identified classes ofvalid input must be accepted.

Invalid Input : identified classes of invalid input must be rejected.

Functions identified functions must be exercised.

Output identified classes of application outputs must be exercised.

Organization and preparation of functional tests is focused on requirements, key functions, or

special test cases. In addition, systematic coverage pertaining to identify Business process flows; data
fields, predefined processes, and successive processes must be considered for testing. Before
functional testing is complete, additional tests are identified and the effective value of current tests is
determined.

6.1.4. SYSTEM TESTING

System testing ensures that the entire integrated software system meets requirements. It tests
a configuration to ensure known and predictable results. An example of system testing is the
configurationoriented system integration test. System testing is based on process descriptions and
flows, emphasizing predriven process links and integration points.\,

6.2. WHITE BOX TESTING

White Box Testing is a testing in which in which the software tester has knowledge of the
inner workings, structure and language ofthe software, or at least its purpose. It is purpose It is used
to test areas that cannot be reached from a black box level.

6.3. BLACK BOX TESTING

Black Box Testing is testing the software without any knowledge of the inner workings,
structure or language of the module being tested. Black box tests, as most other kinds of tests, must
be written from a definitive source document, such as specification or requirements document, such
as specification or requirements document. It is a testing in which the software under test is treated,
as a black box. You cannot
"see" into it. The test provides inputs and responds to outputs without considering how the software
works.

6.4. TEST STRATEGY AND APPROACH

Field testing will be performed manually, and functional tests will be written in detail.

21
Test objectives
All field entries must work properly.
Pages must be activated from the identified link
The entry screen, messages and responses must not be delayed
Features to be tested
Verify that the entries are of the correct format
No duplicate entries should be allowed
All links should take the user to the correct page

Integration Testing
Software integration testing is the incremental integration testing of two or more integrated
software components on a single platform to produce failures caused by interface defects.

The task ofthe integration test is to check that components or software applications, e.g.,
components in a software system or — one step up — software applications at the company level —
interact without error.

Test Results: All the test cases mentioned above passed successfully. No defects encountered.

Acceptance Testing
User Acceptance Testing is a critical phase of any project and requires significant participation
by the end user. It also ensures that the system meets the functional requirements.

Test Results: All the test cases mentioned above passed successfully No defects encountered.

8. SOFTWARE ENVIRONMENT
8.1. JAVA TECHNOLOGY
Java technology is both a programming language and a platform.

The Java Programming Language

The Java programming language is a high-level language that can be characterized by all the
following
Simple
Architecture neutral
Object oriented
Portable
Distributed
High performance
Interpreted
Multithreaded
Robust
Dynamic
Secure
With most programming languages, you either compile or interpret a program so that you can
run it on your computer. The Java programming language is unusual in that a program is both
compiled and interpreted. With the compiler, first you translate a program into an intermediate
language called Java byte codes —the platform-independent codes interpreted by the interpreter on
the Java platform. The interpreter parses and runs each Java byte code instruction on the computer.
Compilation happens just once; interpretation occurs each time the program is executed. The
following figure illustrates how this works:

Fig: 8.1 (a) program compilation and interpretation

26
 You can think of Java byte codes as the machine code instructions for the Java Virtual Machine
(Java VM)_ Every Java interpreter, whether it's a development tool or a Web browser that can run
applets, is an implementation ofthe Java VM_ Java byte codes help make "write once, run anywhere"
possible. You can compile your program into byte codes on any platform that has a Java compiler.
The byte codes can then be run on any implementation ofthe Java VM That means that if a computer
has a Java VM, the same program written in the Java programming language can run on Windows
2000, a Solaris workstation, or on an iMac

Win32 Solaris MacOS

Fig: 8.1(b) program execution example

8.2. JAVA PLATFORM

A platform is the hardware or software environment in which a program runs. We've already
mentioned some of the most popular platforms like Windows 2000, Linux, Solaris, and MacOS. Most
platforms can be described as a combination ofthe operatlng system and hardware. The Java platform
differs from most other platforms in that it's a software-only platform that runs on top of other
hardware-based platforms.

The Java platform has two components:

• The Java V irtual Machine (Java VM)

• The Java Application Programming Interface (Java API)
You've already been introduced to the Java VM It's the base for the Java platform and is ported onto
various hardware-based platforms.

The Java API is a large collection of ready-made software components that provide many
useful capabilities, such as graphical user interface (GUI) widgets. The Java API is grouped into
libraries of related classes and interfaces; these libraries are known as packages.

27
 Java Platform

Fig: 8.2(a) java platform

Native code is code that after you compile it, the compiled code runs on a specific hardware
platform. As a platform-independent environment, the Java platform can be a bit slower than native
code. However, smart compilers, well-tuned interpreters, and just-in-time byte code compilers can
bring performance close to that of native code without threatening portability

What Can Java Technology Do?

The most common types of programs written in the Java programming language are applets and
applications. Ifyou've surfed the Web, you're probably already familiar with applets. An applet is a
program that adheres to certain conventions that allow it to run within a Java-enabled browser.

However, the Java programming language is not just for writing cute, entertaining applets for
the Web. The general-purpose, high-level Java programming language is also a powerful software
platform. Using the generous API, you can \Wite many types of programs.
An application is a standalone program that runs directly on the Java platform. A special kind
of application known as a server serves and supports clients on a network. Examples of servers are
Web servers, proxy servers, mail servers, and print servers. Another specialized program is a servlet.
A servlet can almost be thought of as an applet that runs on the server side. Java Servlets are a popular
choice for building interactive web applications, replacing the use of CGI scripts. Servlets are similar
to applets in that they are runtime extensions of applications. Instead of working in browsers, though,
servlets run within Java Web servers, configuring or tailoring the server.
How does the API support all these kinds of programs? It does so with packages of software
components that provides a wide range of functionality. Every full implementation of the Java
platform gives you the following features:
The essentials: Objects, strings, threads, numbers, input and output, data structures, system
properties, date and time, and so on.
Applets. The set of conventions used by applets.
Networking: URLs, TCP (Transmission Control Protocol), UDP (User Data gram Protocol)
sockets, and
IP (Internet Protocol) addresses.

28
Internationalization. Help for writing programs that can be localized for users worldwide.
Programs can automatically adapt to specific locales and be displayed in the appropriate language.
Security. Both low level and high level, including electronic signatures, public and private key
management, access control, and certificates.
Software components: Known as JavaBeans, can plug into existing component architectures.
Object serialization. Allows lightweight persistence and communication via Remote Method
Invocation (RMI).
Java Database Connectivity (JDBC): Provides uniform access to a wide range of relational
databases. The Java platform also has APIs for 2D and 3D graphics, accessibility, servers,
collaboration, telephony, speech, animation, and more. The following figure depicts what is
included in the Java 2 SDK.

10. INPUT AND OUTPUT DESIGN
INPUT DESIGN

The input design is the link between the information system and the user. It comprises the
developing specification and procedures for data preparation and those steps are necessary to put
transaction data in to a usable form for processing can be achieved by inspecting the computer to
read data from a written or printed document or it can occur by having people keying the data directly
into the system. The design of input focuses on controlling the amount of input required, controlling
the errors, avoiding delay, avoiding extra steps and keeping the process simple. The input is designed
in such a way so that it provides security and ease of use with retaining the privacy. Input Design
considered the following things•

What data should be given as input?

How the data should be arranged or coded?
The dialog to guide the operating personnel in providing input.
Methods for preparing input validations and steps to follow when error occur.

31
OBJECTIVES

Input Design is the process of converting a user-oriented description ofthe input into a computer-
based system. This design is important to avoid errors in the data input process and show the
correct direction to the management for getting correct information from the computerized
system.
It is achieved by creating user-friendly screens for the data entry to handle large volume ofdata_
The goal of designing input is to make data entry easier and to be free from errors. The data
entry screen is designed in such a way that all the data manipulates can be performed. It also
provides record viewing facilities.
When the data is entered it will check for its validity. Data can be entered with the help of screens.
Appropriate messages are provided as when needed so that the user will not be in maize of instant.
Thus, the objective of input design is to create an input layout that is easy to follow

OUTPUT DESIGN

A quality output is one, which meets the requirements of the end user and presents the
information clearly. In any system results of processing are communicated to the users and to other
system through outputs. In output design it is determined how the information is to be displaced for
immediate need and the hard copy output. It is the most important and direct source information to
the user. Effcient and intelligent output design improves the system 's relationship to help user
decision-making.

Designing computer output should proceed in an organized, well thought out manner; the right
output must be developed while ensuring that each output element is designed so that people will
find the system can use easily and effectively. When analysis design computer output, they should
Identify the specific output that is needed to meet the requirements.
Select methods for presenting information.
Create document, report, or other formats that contain information produced by the system.

The output form ofan information system should accomplish one or more ofthe following objectives.

Convey information about past activities, status or projections ofthe

Future.
Signal important events, opportunities, problems, or warnings.
Trigger an action.
