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 UML Use Case Diagrams. Use case diagrams are usually referred to as behavior diagrams used to describe a set of actions () that some system or systems () should or can perform in collaboration with one or more external users of the system ().Each use case should provide some observable and valuable result to the actors or other stakeholders of the system

Abstract Use Case. All UML 2.x specifications including UML 2.5 do not mention, define or explain abstract use cases.UML 1.x specification mentioned that the name of an abstract use case may be shown in italics but since UML 2.0 this sentence was removed from UML specifications without any explanations.. One reason that the sentence was removed could be that because use case is a classifier. Use cases are represented with a labeled oval shape. Stick figures represent actors in the process, and the actor's participation in the system is modeled with a line between the actor and use case. To depict the system boundary, draw a box around the use case itself. UML use case diagrams are ideal for Use-case: Use cases are used to represent high-level functionalities and how the user will handle the system. A use case represents a distinct functionality of a system, a component, a package, or a class. It is denoted by an oval shape with the name of a use case written inside the oval shape. The notation of a use case in UML is given below In software and systems engineering, a use case is a list of actions or event steps typically defining the interactions between a role (known in the Unified Modeling Language (UML) as an actor) and a system to achieve a goal.The actor can be a human or other external system. In systems engineering, use cases are used at a higher level than within software engineering, often representing. A use case describes a sequence of actions that provide a measurable value to an actor. A use case is drawn as a horizontal ellipse on a UML use case diagram, as you see in Figure 1. Use Case Names Begin With a Strong Verb; Name Use Cases Using Domain Terminology; Place Your Primary Use Cases In The Top-Left Corner Of The Diagra

3. A use case diagram at its simplest is a representation of a user's interaction with the system that shows the relationship between the user and the different use cases in which the user is involved.
