What should be included in use case model artifact?
Artifact: Use-Case Model. This artifact is a model of the system’s intended functions and its environment, and serves as a contract between the customer and the developers. It is used as an essential input to activities in analysis, design, and test.
Which is correct for use case dependency?
An include dependency from one use case (called the base use case) to another use case (called the inclusion use case) indicates that the base use case will include or call the inclusion use case. A use case may include multiple use cases, and it may be included in multiple use cases.
What are dependencies in use case diagram?
You can use dependency relationships in class diagrams, component diagrams, deployment diagrams, and use-case diagrams to indicate that a change to the supplier might require a change to the client. You can also use a dependency relationship to represent precedence, where one model element must precede another.
What is dependency in use case?
In an Unified Modeling Language (UML) use case diagram, an include dependency is a generalization relationship that describes the inclusion of the behavior described by another use case. A UML use case can include more than one use cases and it can be included in multiple use cases.
Which actor has an interest in the Behaviour of use case?
Offstage actor
Often a computer system, but could be an organization or person. Why identify? To clarify external interfaces and protocols. Offstage actor—has an interest in the behavior of the use case, but is not primary or supporting; for example, a government tax agency.
What is the difference between association and dependency?
An association almost always implies that one object has the other object as a field/property/attribute (terminology differs). A dependency typically (but not always) implies that an object accepts another object as a method parameter, instantiates, or uses another object.
What are the three main scope levels of use cases?
Cockburn distinguishes three main levels of use cases, being Summary, User Goal and Subfunction.
How to show the include keyword in UML?
An include dependency is shown as a dashed arrow from the base use case to the inclusion use case marked with the include keyword. The base use case is responsible for identifying where in its behavior sequence or at which step to include the inclusion use case.
Which is an artifact of the use case?
These related artifacts consist typically of the collaboration and sequence diagrams which express the behavior of the use case in terms of collaborating objects. Properties Property Name Brief Description UML Representation
When to use include dependency in a project?
You can use an include dependency when a use case may be common to multiple other use cases and is therefore factored out of the different use cases so that it may be reused. The Log Activity use case in Figure 4-6 is included in the Manage Project, Manage Resource, and Administer System use cases.
What does include mean in a use case?
An include dependency from one use case (called the base use case) to another use case (called the inclusion use case) indicates that the base use case will include or call the inclusion use case. A use case may include multiple use cases, and it may be included in multiple use cases.
