1: INTRODUCTION
1.1 Abstract
Electricity consumers are often faced with the problem of inaccuracy and delay in
monthly billing due to the drawback in reading pattern and human errors. Thus, it
is essential to have an efficient system for such purposes via electronic platform with
consideration to proximity. The proposed system automates the conventional
process of paying electricity bill by visiting the Electricity Board which is
tiresome and time consuming. It is also designed to automate the electricity bill
calculation and payment for user convenience. The Microsoft Structured Query
Language (SQL) server is also used for creating back-end database. The system
would be having two logins: the administrative and user login. The administrator can
view the user’s account details and can add or update the customer’s information of
consuming units of energy of the current month in their account. The Admin has
to feed the system with the electricity usage data into respective users account. The
system then calculates the electricity bill for every user and updates the
information into their account every month. Users can then view their electricity bill
and pay before the month end.

1.2 Existing System and Need for System
Existing System:
In existing system following are key point:
 Limited Accessibility: Traditional stores and physical suppliers often have limited
geographical reach. Customers may need to travel long distances to access a diverse
range of car accessories, which can be time-consuming and costly.
 Limited Product Information: Physical stores may provide limited information
about car accessories and auto parts, making it challenging for customers to make
informed purchasing decisions. Comprehensive product details, specifications, and
customer reviews are often lacking.

7
Need for System:
The need for a new system arises from several factors:
 Enhanced Accessibility: The e-commerce platform provides a global reach,
allowing customers from various locations to access an extensive catalog of car
accessories and auto parts, eliminating the need for physical travel.
 Comprehensive Product Information: Detailed product descriptions,
specifications, high-quality images, and customer reviews empower customers
with the information they need to make informed purchasing decisions.
 Efficient Ordering: The system streamlines the ordering process by enabling
customers to place orders online, reducing manual intervention, errors, and
processing time.
 Secure Transactions: A secure payment gateway ensures the confidentiality of
customer data and financial information, mitigating security concerns associated
with traditional payment methods.

1.5 Brief Description of Technology Used JAVA:
Java is one of the most popular and widely used programming language and
platform. A platform is an environment that helps to develop and run pro- grams written
in any programming language. Java is fast, reliable and secure. From desktop to web
applications, scientific supercomputers to gaming consoles, cell phones to the Internet,
Java is used in every nook and corner. Java is a programming language and computing
platform first released by Sun Microsystems in 1995. There are lots of applications and
websites that will not work unless you have Java installed, and more are created every
day. Java is fast, secure, and reliable. From laptops to datacenters, game consoles to
scientific supercomputers, cell phones to the Internet, Java is everywhere! Java is a
general-purpose, concurrent, object-oriented, classbased, and the run- time environment
(JRE) which consists of JVM which is the cornerstone of the Java platform. This blog
on what is Java will clear all your doubts about why to learn java, features and how it
works.
JDK:
The Java Development Kit (JDK) is an implementation of either one of the Java
Platform, Standard Edition, Java Platform, Enterprise Edition, or Java Platform, Micro
Edition platforms released by Oracle Corporation in the form of a binary product aimed
at Java developers on Solaris, Linux, macOS or Windows. The JDK includes a private
JVM and a few other resources to finish the development of a Java Application. Since
the introduction of the Java platform, it has been by far the most widely used Software
Development Kit (SDK). On 17 November 2006, Sun announced that they would release
it under the GNU General Public License (GPL), thus making it free software. This
happened in large part on 8 May 2007, when Sun contributed the source code to the
OpenJDK.

2. PROPOSED SYSTEM
Proposed System:
Key Components of the Proposed System:
• User Registration and Authentication: The system will allow users to create
accounts, providing essential information such as name, contact details, and
shipping address. Account creation ensures a personalized experience and the ability
to track orders.
• Product Catalog: A comprehensive catalog of carbide tools will be featured on the
website, complete with product descriptions, specifications, high-resolution images,
and pricing information. Products will be organized into categories and
subcategories for easy navigation.
• Search and Filter Functionality: Users can search for specific car accessory by
name, size, length, diameter, category, or material. Advanced filtering options will
enable users to refine their searches based on criteria like price range, brand, and
specifications.
• Product Details: Detailed product pages will provide in-depth information about
each car accessory, including material, dimensions, applications, and customer
reviews. Users can add items to their shopping carts directly from these pages.
• Shopping Cart: A user-friendly shopping cart system will allow customers to
review, modify, and finalize their orders. The cart will display the total cost,
including taxes and shipping fees, before checkout.
• Secure Checkout: The system will integrate a secure payment gateway to facilitate
smooth and secure transactions. Multiple payment options, including credit/debit
cards and digital wallets, will be supported.
• Order Management: Registered users can track their order status and history. They
will receive email notifications at various stages of the order processing, from order
confirmation to shipment tracking.
• User Reviews and Ratings: Customers can leave reviews and ratings for products
they have purchased, helping others make informed decisions.

12
• Responsive Design: The website will be responsive, ensuring a seamless user
experience across devices, including desktops, tablets, and smartphones.

13
sibility Study:
echnical Feasibility
•Java: Java is a mature and widely used programming language known for its
portability, scalability, and robustness. Leveraging Java as the core programming
language for the e-commerce site ensures platform independence, allowing it to run on
various operating systems.
•JSP (Java Server Pages) and Servlets: JSP and Servlets are fundamental components
of the Java EE (Enterprise Edition) stack, specializing in dynamic web page creation
and handling user interactions. They enable the development of responsive and
interactive web interfaces, making them suitable for building an e-commerce site with
rich features.
•Hibernate: Hibernate is an Object-Relational Mapping (ORM) framework that
simplifies database interactions by mapping Java objects to database tables. Its use in
this project streamlines data management, enhancing data integrity and performance.
•Relational Database: An e-commerce site for carbide tools requires efficient data
storage and retrieval. Hibernate, in combination with a relational database management
system (RDBMS) such as MySQL or PostgreSQL, ensures organized and structured
data storage. This choice supports complex queries, relationships, and transactions.
•Payment Gateways: Integrating secure and reliable payment gateways, such as PayPal
or Stripe, is crucial for processing online transactions securely.

14
 Economic Feasibility
• Cost Analysis: The economic feasibility analysis begins with a comprehensive cost
assessment. This includes the initial development costs, which involve hiring skilled
Java developers, web designers, and database administrators to build and launch the
platform. Additionally, ongoing operational costs such as hosting, maintenance, and
marketing expenses need to be factored in.
• Revenue Projections: Revenue generation is a central aspect of economic feasibility.
Projections are made based on the expected sales volume, average order value, and
pricing strategy for car accessories . Market research and competitive analysis are
instrumental in estimating the potential market share and revenue growth.
• Return on Investment (ROI): Calculating the ROI involves comparing the expected
returns from the e-commerce site to the initial investment. This metric helps
stakeholders determine how long it will take to recoup the development and operational
expenses and start generating profit.
• Scalability and Growth Potential: Economic feasibility also involves assessing the
scalability of the e-commerce site. Can it handle an increase in traffic and transactions
without a proportionate increase in costs? Identifying opportunities for growth, such as
expanding product offerings or entering new markets, is crucial.

15
 Operational Feasibility
• User-Friendly Interface: The operational feasibility of our e-commerce site begins
with its user-friendly interface. The Java, JSP, Servlet, and Hibernate technologies
allow for the creation of an intuitive and responsive website, making it easy for
users to navigate, search for products, and complete transactions. This user-
friendliness ensures that both tech-savvy and non-technical users can interact with
the platform comfortably.
• Scalability: One of the key operational aspects is the platform's ability to scale
with the growth of the business. Using Java and Hibernate, our e-commerce site can
accommodate an expanding product catalog, increased user traffic, and additional
features without compromising performance. This scalability is essential for
adapting to changing business requirements.
• Maintenance and Updates: The operational feasibility study also considers the ease
of maintaining and updating the system. Java, JSP, Servlet, and Hibernate offer a
structured and modular approach to development, making it relatively
straightforward to add new features, fix bugs, and apply security patches. This
ensures that the e-commerce platform can be efficiently maintained over time.

16
ectives of the proposed system:
The objectives of the e-commerce system for car accessories are to create a robust and
feature-rich platform that serves the needs of both customers and administrators. The
following are the primary objectives:
• User-Friendly Interface: Design a user-friendly and intuitive interface that encourages
easy navigation and product discovery.
• Comprehensive Product Listings: Ensure an extensive and up-to-date product catalog,
including detailed descriptions and images for each car accessory
• Security: Implement robust security measures to protect user data and financial

3. ANALYSIS AND DESIGN
3.1 Entity Relationship Diagram (ERD):
ER Diagram stands for Entity Relationship Diagram, also known as ERD is a diagram that displays the
relationship of entity sets stored in a database. In other words, ER diagrams help to explain the logical
structure of databases. ER diagrams are created based on three basic concepts: entities, attributes and
relationships.ER Diagrams contain different symbols that use rectangles to represent entities, ovato
define attributes and diamond shapes to represent relationships.
Entity Relationship Diagram
ER Diagram in DBMS An Entity–relationship model (ER model) describes the structure of a database
with the help of a diagram, which is known as Entity Relationship Diagram (ER Diagram). An ER
model is a design or blueprint of a database that can later be implemented as a database. The main
Components of E-R model are:
Entity set and relationship set. What is an Entity Relationship Diagram (ER Diagram)? An ER diagram
shows the relationship among entity sets. An entity set is a group of similar entities and these entities
can have attributes.
In terms of DBMS, an entity is a table or attribute of a table in database, so by showing relationship
among tables and their attributes, ER diagram shows the complete logical structure of a database. Lets
have a look at a simple ER diagram to understand this concept
Facts about ER Diagram Model:

19
ER model allows you to draw Database Design It is an easy to use graphical tool for modeling data
Widely used in Database Design It is a GUI representation of the logical structure of a Database It helps
you to identifies the entities which exist in a system and the relationships between those entitie
Why use ER Diagrams?
Here, are prime reasons for using the ER Diagram Helps you to define terms related to entity
relationship modeling Provide a preview of how all your tables should connect, what fields are going
to be on each table Helps to describe entities, attributes, relationships ER diagrams are translatable into
relational tables which allows you to build databases quickly ER diagrams can be used by database
designers as a blueprint for implementing data in specific software applications.
A simple ER Diagram:
In the following diagram we have two entities Student and College and their relationship. The
relationship between Student and College is many to one as a college can have many students however
a student cannot study in multiple colleges at the same time. Student entity has attributes such as Stu_Id,
Stu_Name & Stu_Addr and College entity has attributes such as Col_ID & Col_Name
Here are the geometric shapes and their meaning in an E-R Diagram
We will discuss these terms in detail in the next section (Components of a ER Diagram) of this guide
so don’t worry too much about these terms now, just go through them once.
Rectangle: Represents Entity sets. Ellipses: Attributes

20
Diamonds: Relationship Set
Lines: They link attributes to Entity Sets and Entity sets to Relationship Set Double Ellipses:
Multivalued Attributes
Dashed Ellipses: Derived Attributes Double Rectangles: Weak Entity Sets
Double Lines: Total participation of an entity in a relationship set

22
3.2 Class Diagram :
In software engineering, a class diagram in the Unified Modeling 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 objects.
The class diagram is the main building block of object-oriented modeling. It is used for general conceptual
modeling of the structure of the application, and for detailed modeling, translating the models into
programming code. Class diagrams can also be used for data modeling.[1] The classes in a class diagram
represent both the main elements, interactions in the application, and the classes to be programmed.
In the diagram, classes are represented with boxes that contain three compartments:
 The top compartment contains the name of the class. It is printed in bold and centered, and the first letter
is capitalized.
 The middle compartment contains the attributes of the class. They are left-aligned and the first letter is
lowercase.
 The bottom compartment contains the operations the class can execute. They are also left-aligned and the
first letter is lowercase.
In the design of a system, a number of classes are identified and grouped together in a class diagram that helps
to determine the static relations between them. In detailed modeling, the classes of the conceptual design are
often split into subclasses.
In order to further describe the behavior of systems, these class diagrams can be complemented by a state
diagram or UML state machine.

24
3.3 Use Case Diagram :
To model a system, the most important aspect is to capture the dynamic behavior.
Dynamic behavior means the behavior of the system when it is running/operating.
Only static behavior is not sufficient to model a system rather dynamic behavior is more important than
static behavior. In UML, there are five diagrams available to model the dynamic nature and use case
diagram is one of them. Now as we have to discuss that the use case diagram is dynamic in nature, there
should be some internal or external factors for making the interaction.
These internal and external agents are known as actors. Use case diagrams consists of actors, use cases
and their relationships. The diagram is used to model the system/subsystem of an application. A single
use case diagram captures a particular functionality of a system.
Hence to model the entire system, a number of use case diagrams are used.

25
 Purpose of use case diagram
The purpose of use case diagram is to capture the dynamic aspect of a system. However, this definition is
too generic to describe the purpose, as other four diagrams (activity, sequence, collaboration, and
Statechart) also have the same purpose. We will look into some specific purpose, which will distinguish
it from other four diagrams.
Use case diagrams are used to gather the requirements of a system including internal and external
influences. These requirements are mostly design requirements. Hence, when a system is analyzed to
gather its functionalities, use cases are prepared and actors are identified.
When the initial task is complete, use case diagrams are modelled to present the outside view.
In brief, the purposes of use case diagrams can be said to be as follows
 Used to gather the requirements of a system.
 Used to get an outside view of a system.
 Identify the external and internal factors influencing the system.
 Show the interaction among the requirements are actors.

28
Activity Diagram :
An activity diagram is a type of Unified Modeling Language (UML) flowchart that shows the flow from
one activity to another in a system or process. It's used to describe the different dynamic aspects of a
system and is referred to as a 'behavior diagram' because it describes what should happen in the modeled
system.
Even very complex systems can be visualized by activity diagrams. As a result, activity diagrams are
often used in business process modeling or to describe the steps of a use case diagram within
organizations. They show the individual steps in an activity and the order in which they are presented.
They can also show the flow of data between activities.
Activity diagrams show the process from the start (the initial state) to the end (the final state). Each
activity diagram includes an action, decision node, control flows, start node, and end node.
Benefits of activity diagrams :
 Here are some of the key benefits of using activity diagrams to show the flow of activities in a
system or process within your organization:
Shows the progress of workflow amongst the users, and the system
 Activity diagrams clearly show the progress of workflow between the users. This makes it easier for
managers to see what's working well and where the bottlenecks are within the system to make
relevant changes.
Demonstrates the logic of an algorithm
 Activity diagrams provide a clear visualization of the logic of an algorithm. This provides a clear
view of what's happening behind the scenes and makes it easy to identify what's working well and
needs improvement. Vividly shows the steps taken when performing a UML use case.
 A use case diagram is designed to show the different ways a user may interact with a system. An
activity diagram vividly shows every single step taken within this use case diagram. This helps
business managers to visualize business processes within the organization fully.
 Models the software architecture elements, including the method, operation, and function
 Activity diagrams can be used to model software architecture elements within a system by showing
the relationships between the components and the constraints for assembling these components.
This can provide a better understanding of how the system works.
 Simplifies the majority of the UML processes by clarifying complicated use cases

29
 Use cases can either be sequential or concurrent. Concurrent use cases can be tough to describe, as
many different processes are happening simultaneously. Activity diagrams provide a clear
visualization of these processes, making them easier to understand.

32
3. Sequence Diagram
To understand what a sequence diagram is, it's important to know the role of the Unified Modeling Language,
better known as UML.
UML is a modeling toolkit that guides the creation and notation of many types of diagrams, including behavior
diagrams, interaction diagrams, and structure diagrams.
A sequence diagram is a type of interaction diagram because it describes how and in what order—a group of
objects works together.
These diagrams are used by software developers and business professionals to understand requirements for a
new system or to document an existing process. Sequence diagrams are sometimes known as event diagrams
or event scenarios.
Note that there are two types of sequence diagrams: UML diagrams and code-based diagrams. The latter is
sourced from programming code and will not be covered in this guide.
Lucid chart’s UML diagramming software is equipped with all the shapes and features you will need to model
both.
Benefits of sequence diagrams
Sequence diagrams can be useful references for businesses and other organizations. Try drawing a sequence
diagram to:
Represent the details of a UML use case.
Model the logic of a sophisticated procedure, function, or operation.
See how objects and components interact with each other to complete a process.
Plan and understand the detailed functionality of an existing or future scenario.

33
Use cases for sequence diagrams
The following scenarios are ideal for using a sequence diagram:
Usage scenario: A usage scenario is a diagram of how your system could potentially be used. It's a great way
to make sure that you have worked through the logic of every usage scenario for the system.
Method logic: Just as you might use a UML sequence diagram to explore the logic of a use case, you can use
it to explore the logic of any function, procedure, or complex process.
Service logic: If you consider a service to be a high-level method used by different clients, a sequence diagram
is an ideal way to map that out.
Sequence diagram Visio - Any sequence diagram that you create with Visio can also be uploaded into
Lucidchart. Lucidchart supports .vsd and .vdx file import and is a great Microsoft Visio alternative. Almost
all of the images you see in the UML section of this site were generated using Lucidchart.

 Module Hierarchy Diagram
The hierarchy chart is a graphical representation that is used to represent the relationship between
various modules or systems in an organization. In programming, a hierarchy chart is used for
representing an organizational framework. The hierarchy charts can also be utilized to show an
organization’s reporting structure.
In such a hierarchy chart, the President is at the top, the Vice Presidents are on the next level which is
lower than its predecessor, and so forth. Within the context of a software program, it indicates the
relationship among modules (or capabilities).
The design team members create hierarchy charts to represent the relationship between modules in an
application.
Concept of the hierarchy chart
The hierarchy chart is a structure chart that is used to represent the control information and data that
gets exchanged between the modules. In a hierarchy chart, a rectangular symbol is used to represent
each module. An arrow sign with an open circle at the source end is used to represent each data pair
or flow of data.
The workflow, code selection and logical structures of the code are not shown in the structure chart.
However, some creators and designers include transaction hubs in a control module by identifying
high-level case structures.
Designers create a program using a hierarchy chart in the same way that an architect creates a plan
for a house. Each of the functions or modules are placed at their correct positions and also the flow of
data between the various modules is also listed.
An example of the hierarchy chart for a software application is discussed in the last section of this
article.
How to create Hierarchy chart to represent an organization's structure?

36
Find the most essential entity of the system. For example, the CEO is in the highest position in an
organization.
Choose the components for the second level, third level, fourth level, and so on. List them down.
Once you list them down in the hierarchy chart, connect them to show the relationship between
entities and their parts.
If one wants to add some more information, one can add them to the chart. Use themes available to
color the chart in order to make it visually attractive.
Download the hierarchy chart in an available format like png, jpg, etc., in order to use it in
presentations and documents.

37
Components of a Hierarchy chart
1.Module - It represents a task or a process.
Sub Module: It is a module that is actually a part of another module.
Control Module: It is a module responsible for coordinating several sub-modules. Library Module: It
is a module that can be called and reused by other modules.
2.Conditional Call - denotes a control module that has the ability to select any sub Module based on
a set of circumstances.
3.Loop - The loop refers to the repeated execution of a set of modules.
4.Data Flow - The flow of data between modules is represented by data flow. A directed Arrow with
an empty circle at the end represents it.
5.Control Flow - It depicts the control flow between the modules. A directed arrow with a filled
circle at the end is also used to express it.
6. Physical Storage- It is a storage space for all of the information.

5 : Limitations of System:
Limited scalability: The system may struggle to handle sudden spikes in
traffic or increased demand during peak periods.
 Security vulnerabilities: It might be prone to cybersecurity threats like
data breaches or hacking due to potential loopholes in security measures.
 Lack of personalization: Inadequate customization options may restrict
the ability to tailor the user experience for individual customers.
 Compatibility issues: It could face challenges in integrating with newer
technologies or software updates, potentially causing functionality issues.
 Performance bottlenecks: Slow loading times or processing delays may
hinder the overall user experience, impacting customer satisfaction

77
6 : Proposed Enhancement
 Diverse Payment Options: Integrate various payment gateways
(credit/debit cards, PayPal, digital wallets) to offer customers flexibility
in their payment methods.
 Customized Quotation System: Implement a quoting system where
customers can request custom quotes for bulk orders or specific tool
configurations. This could involve a form where they input quantities,
specifications, and receive tailored pricing.
 Payment Security Measures: Strengthen the site's security protocols by
using SSL certificates, encryption, and two-factor authentication to
safeguard sensitive payment information and build customer trust.

78
7 : Conclusion
In conclusion, while the ecommerce site for car accessories e commerce offers a
valuable
platform, its success hinges on addressing key areas like scalability, security,
personalization, compatibility, and performance. Investing in these aspects can
significantly enhance user experience, security measures, and adaptability,
ensuring sustained growth and customer satisfaction within the competitive
market of car accessories and tools.
