1 Introduction
In this report, the team will carry out discussions about OPP (Object-Oriented Programming) and the
different class relationships of OOP. Our team will then proceed to build an OOP scenario with the example
of a commercial e-site that includes a Use case diagram and a class diagram along with an explanation.
Finally, our team will discuss design patterns including Creational, Structural, Behavioral with their
introduction, scenario description, and diagram along with detailed explanations.
2 OOP general concepts
OOP is also known as Object-Oriented Programming. OOP is a common term and it is also a very important
and much-used programming technique today. OOP is a programming technique that allows programmers
to design and develop software based on class and object architecture. In object-oriented programming,
each programmer's program will have several objects that can interact with each other, belonging to
different classes, and each object will manage its own data (Attvater, 2017).
2.1 Object and Class in OOP
a) Object
An object is a software that includes related properties and methods. Specifically, an object consisting of
2 information is attributes and methods. Example "Student":
 (Attributes) are the information and characteristics of the subject: full name, age, score, ...
