Report on UML Class Diagram for Fast Food Restaurant Design Pattern

This report analyzes a UML class diagram for a fast-food restaurant, detailing its construction and application in system design. The report explains the use of UML diagrams for visually representing system models, including classes and actors, and how they aid in software development. It describes the structure of a class diagram, including classes, attributes, and operations, and how these elements communicate within the system. The report highlights the benefits of UML diagrams, such as providing a top-level view of the system and improving project health, while also acknowledging the need for specialized tools like MS Visio for creating enhanced diagrams. The report includes a sample class diagram and concludes by emphasizing the importance of UML diagrams in understanding design patterns and facilitating software development in the context of fast-food restaurant systems.

Introduction
The UML or a unified Modelling Language diagram is used to build a design pattern of
any system. It is able to represent the model visually. It can represent every class and every
actor. This diagram can help a developer to complete their projects. In this report, a class
diagram is developed by using UML. With the help of the case study, this class diagram is
developed and this report can provide the construction process of a class diagram.
Discussion
A UML class diagram is used to represent the functional requirements of the specific
system with the help of classes. With the help of the UML class diagram, a person can get basic
information on the system. It can communicate with the different aspects of a system. A class
diagram is able to generate the top-level view of a specific system and it can hide the important
aspects but in the end, this diagram can execute the whole project. Before start coding, a
developer design the prototype of a system. The class diagram provides an overview of a system
that can help a developer to complete the entire project. It can improve project health. After
completing the writing code, a developer can generate this diagram to provide an overview of the
projects. It can identify every activity and workflow of the project. Sometimes, the UML
diagram works as the complete design of a system but it required CASE tools (Helmers, 2015).
But everyone is not able to use the case tool, it required certain expertise to use this kind of
application.
UML diagrams are not a programming language like other stand-alone languages.
But with the help of proper tools, it can be work as pseudo programming. By using the right
software, UML diagrams can be converted into the code. This is a useful method for developers.

Drawing diagrams takes less time and effort than writing codes. With the minimum time span the
entire code can be generated from the drawing. UML is not only used for programming
purposes, but it can also use in business and non-IT systems.
A class diagram is one of the popular diagrams in the software industry. Nowadays, most of the
programing language follow OOP paradigm (Jana, 2014). By using a class diagram, OOP based
software can be developed easily. This diagram contains every class with their attribute (Ho-
Quang et al., 2014). Every class has a specific three sections. At the top, class names is
mentioned. Below the class name, the attribute name is defined and in the end, it indicates the
functions.
To construct a class diagram a developer needs to create a class, attributes and operations.
Class name always start with the capital letter and bold format. An attribute is a property of a
class and it can describe a class. Operation of the class provides the several operations within
class. It can be a function or relationship in the class.

The above class diagram can determine every important class in the fast-food restaurant
and it shows the communications between every classes (Object Oriented Design, 2020).

Conclusion
In conclusion, it can be stated that the role of the UML diagram is one of the main
attributes of this project. Based on the project case study, this class diagram is developed. To
develop an enhanced class diagram, MS Visio is used. MS Visio is one of the best and

appropriate tools to develop a class diagram. This diagram can help to understand the design
pattern of fast-food restaurants.
