What is include relationship in use case?
In UML modeling, an include relationship is a relationship in which one use case (the base use case) includes the functionality of another use case (the inclusion use case). The include relationship supports the reuse of functionality in a use-case model.

What is use case diagram explain with example?
A use case diagram is a graphical depiction of a user’s possible interactions with a system.

The use cases are represented by either circles or ellipses.
What is relationship in use case diagram?
In UML, a relationship is a connection between model elements. A UML relationship is a type of model element that adds semantics to a model by defining the structure and behavior between the model elements.
What are the two types of relationships between use cases?
There can be 5 relationship types in a use case diagram.
- Association between actor and use case.
- Generalization of an actor.
- Extend between two use cases.
- Include between two use cases.
- Generalization of a use case.
What is a sample use case?
A use case is a description of how a person who actually uses that process or system will accomplish a goal. For example, imagine you’re a cook who has a goal of preparing a grilled cheese sandwich. The use case would describe through a series of written steps how the cook would go about preparing that sandwich.
How do you do a use case diagram?
How to Draw a Use Case Diagram?
- Identify the Actors (role of users) of the system.
- For each category of users, identify all roles played by the users relevant to the system.
- Identify what are the users required the system to be performed to achieve these goals.
- Create use cases for every goal.
- Structure the use cases.
What are components of a use case diagram?
Use case diagram components An actor can be a person, an organization, or an outside system that interacts with your application or system. They must be external objects that produce or consume data. System: A specific sequence of actions and interactions between actors and the system.

How is the include relationship used in a use case?
As the name implies, the include relationship is a relationship that can exist between two use cases. It allows you to insert the behavior from one use case into another. In other words, at some point in Use Case A, you’d jump over to Use Case B, move through those steps, then return back to where you left off in Use Case A.
How is the include relationship used in UML?
UML Use Case Include. Use case include is a directed relationship between two use cases which is used to show that behavior of the included use case (the addition) is inserted into the behavior of the including (the base) use case. The include relationship could be used: to simplify large use case by splitting it into several use cases,
How to explain relationships in use case diagrams?
When it comes to drawing use case diagrams one area many struggles with is showing various relationships in use case diagrams. In fact many tend to confuse < >, < > and generalization. This article will look into various use case diagram relationships in detail and explain them using examples.
What should be included in a use case template?
You need to define the flow of the process that starts when a use case is started. The flow needs to detail how the communication will flow, who the information will be displayed to, what they need to do, and where the primary actor will end up. There are 3 things which you need to mention when writing the flow.
