Hospital Management System is a large system including several subsystems or modules providing variety of functions. UML use case diagram example below shows actor and use cases for a hospital's reception. Purpose: Describe major services (functionality) provided by a hospital's reception.
Use Case Diagram Guidelines. Although use case diagrams can be used for various purposes there are some common guidelines you need to follow when drawing use cases. These include naming standards, directions of arrows, the placing of use cases, usage of system boxes and also proper usage of relationships.
Actor in a use case diagram is any entity that performs a role in one given system. This could be a person, organization or an external system and usually drawn like skeleton shown below. A use case represents a function or an action within the system.

This Use Case Diagram is a graphic depiction of the interactions among the elements of Hospital Management System. It represents the methodology used in system analysis to identify, clarify, and organize system requirements of Hospital Management System.
Use-case diagrams describe the high-level functions and scope of a system. These diagrams also identify the interactions between the system and its actors. The use cases and actors in use-case diagrams describe what the system does and how the actors use it, but not how the system operates internally.

A use case is a written description of how users will perform tasks on your website. It outlines, from a user's point of view, a system's behavior as it responds to a request. Each use case is represented as a sequence of simple steps, beginning with a user's goal and ending when that goal is fulfilled.
UCDs have only 4 major elements: The actors that the system you are describing interacts with, the system itself, the use cases, or services, that the system knows how to perform, and the lines that represent relationships between these elements.
As mentioned, the three basic elements that make up a use case are actors, the system and the goal.
The primary event initiating a use case is called a stimulus. The secondary events that are part of the use case dialogue are called interactions. The dialogue with the actor contains all events and their related information. Events are objects and may participate in an inheritance relationship.

The main purpose is to present all functional requirements of the system diagrammatically with all the users who can access the functionality. The presentation is from the perspective of all users giving a high-level design and basic flow of events of the system.
Use Case diagram is a functional requirement documentation technique. It elicits the functionality as a black box with all the users who have access or a role in it.
When a use case can be associated with multiple Actors, then it’s a case of multiplicity of a use case. For example, as shown in the above image “Notation- Relationship And Association”, View-Courses’ is associated with two actors–‘New-User’ and ‘Registered-User’.
Extend is a relationship between two use cases. One is called the extended use case and the other extending use case.
Listed below are some readiness points before starting to draw a use case diagram to represent a System:
The current section explains the step-by-step approach to draw Use Case diagram. Refer to the ‘Document Sample’ and select the ‘System’ with status – Approved i.e. ‘Online Training Registration’. Change the status to Use Case Diagram ‘started’ to facilitate progress tracking of each System.
Example 1: This diagram represents a system named Student Management System that has five functionalities in scope.
A use case diagram is a visual representation of the different ways and possible scenarios of using a system. It illustrates how a user will perform actions and interact with a particular system, such as a website or an app.
Use case diagrams can aid your development process with the following benefits:
There are many different types of diagrams that can be used for designing and representing systems and processes. As for UML use case diagrams, they are classified into two types: behavioral and structural UML diagrams.
Use case diagrams contain a combination of different elements and specialized symbols and connectors. Whether you want your use case diagram to be simple or in-depth, it should include the following basic components:
Here are some use case diagram templates and examples to guide your diagram creation process:
Use case diagrams describe the relationship between the users, the system, and its use cases. They do not need to go into a lot of detail and explain how the system operates internally. Here is a guide on what to include and what not to include in your use case diagram:
Creating a use case diagram can help you illustrate how your system can fulfill the needs and goals of your users. Make sure to use Venngage’s diagram maker to create a successful use case diagram for your next project.
These include naming standards, directions of arrows, the placing of use cases, usage of system boxes and also proper usage of relationships.
Use case diagram is a behavioral UML diagram type and frequently used to analyze various systems. They enable you to visualize the different types of roles in a system and how those roles interact with the system. This use case diagram tutorial will cover the following topics and help you create use cases better.
So all of these can be considered as use cases. Top level use cases should always provide a complete function required by an actor.
System. The system is used to define the scope of the use case and drawn as a rectangle. This an optional element but useful when you’re visualizing large systems. For example, you can create all the use cases and then use the system object to define the scope covered by your project.
