Order class is an abstract class and it has two concrete classes inheritance relationship SpecialOrder and NormalOrder. Use case diagrams consists of actors, use cases and their relationships. From the name, it is clear that the diagram deals with some sequences, which are the sequence of messages flowing from one object to another. 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. The same is true for reverse engineering.

Actually these specific purposes are different angles of a running system.
UML - Basic Notations
These diagrams have a better impact on our understanding. Hence, visualization is the most important part which needs to be understood and remembered. This high level design is refined again and again to get a complete and practical picture of the system. Class diagram describes the attributes and operations of a class and also the constraints imposed on the system. Use case diagrams are a set of use cases, actors, and their relationships.
UML - Useful Resources
It is basically additional elements used to represent some extra behavior of the system. If we look around, we will realize that the diagrams are not a new concept but it is used widely in different forms in different industries. These controllers are known as actors.
Initial state is defined to show the start of a process. A use case represents a particular functionality of a system. The notations are described in the following diagram. Sequence diagram is used to visualize the sequence of calls in a system to perform a specific functionality. Class diagram is not only used for visualizing, describing, and documenting different aspects of a system but also for constructing executable code of the software umk.
Hence, UML has notes notation to support this requirement. Object diagrams are a set of objects and their relationship is just like class diagrams. Tutorialspoiint static behavior is not sufficient to model a system rather dynamic behavior is more important than static behavior. When a class implements the interface, it also implements the functionality as per requirement. Now, these groups are known as components.
UML - Use Case Diagrams
Dependency is represented by a dotted arrow as shown in the following figure. This is prepared to have an idea of how the system will work when executed. This notation is also used in almost all diagrams to describe the end.
These events are responsible for state change of tugorialspoint system. Object diagrams can be described as an instance of class diagram.
Different notations are available for things and relationships.
It describes a particular aspect of the entire application. The purpose of use case diagram is to capture the dynamic aspect of tutorialspooint system.
Interface is just like a template where you define different functions, not the implementation. The class diagrams are widely used in the modeling of objectoriented systems because they are the only UML diagrams, which can be mapped directly with object-oriented languages.
Structural organization consists of objects and links. We can say that use cases are nothing but the system functionalities umk in an organized manner. We will look into some specific purpose, which will distinguish it from other four diagrams. Use case diagrams are considered for high level requirement analysis of a system. It consists of activities and links. Another important point is to identify the system boundary, which is shown in tktorialspoint picture.
The static view describes the vocabulary of the system. Deployment diagrams are used for visualizing the deployment view of a system.
