Can Use Case Include A Use Case And Include A Use Case

Include use case is one where a use case incorporates another use case. In UML notation the include relationship annotated with the ltltincludegtgt keyword and a dashed arrow pointing towards the include use case. Include relationship may or may not appear on its own as a behavior sequence.

Include Relationship Between Two Use Cases. Include relationship show that the behavior of the included use case is part of the including base use case. The main reason for this is to reuse common actions across multiple use cases. In some situations, this is done to simplify complex behaviors. Few things to consider when using the ltltinclude

In include relationships, the arrow points from the including use case to the included use case, indicating that the included use case is always necessary. 3. Triggers and Preconditions Extend relationships are triggered by some condition or event that occurs during the execution of the base use case, which is defined by a precondition.

This means that the included use case cannot be performed without the presence of the including use case. The include relationship is depicted by a solid line with an open arrowhead pointing towards the included use case. This relationship is typically used when a use case represents a common behavior that is reused within other use cases

The arrow goes from the extending use case to the use case being extended, which is sort of the backwards of includes. An example of an extend in your case might be a Transfer Cash use case that could extend Verify Balance, which in the event that the balance were insufficient for the transaction would attempt to cover it from another account

Use Cases Compose Post, Add Image Include Relationship The quotCompose Postquot use case includes the functionality of quotAdd Image.quot Therefore, composing a post includes the action of adding an image. 3. Extend Relationship. The Extend Relationship illustrates that a use case can be extended by another use case under specific conditions.

The time to use the ltltincludegtgt relationship is after you have completed the first cut description of all your main Use Cases. You can now look at the Use Cases and identify common sequences of user-system interaction. When a use case is depicted as using the functionality of another use case, the relationship between the use cases is named as

Include use cases are used to represent functionality that is shared across multiple use cases. They allow you to avoid duplicating the same functionality across multiple use cases, and instead refer to a single use case that contains the shared functionality. This can help to reduce the complexity of your use cases, and make them easier to

Example 1 - Simple Use Case 2 We can use Use Cases in other contexts, for example to describe some common framework code or an infrastructure subsystem. In this case the description of the Use Cases would treat the business application as the Actor and is written from the view point of the application developer, who plays the part of the user

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, to extract common parts of the behaviors of two or
