It represents the methodology used in system analysis to identify, clarify, and organize system requirements of Inventory Management System. This type of relationship reveals details about the system or application that are usually hidden in the use case.This Use Case Diagram is a graphic depiction of the interactions among the elements of Inventory Management System. In UML modeling, you can use an extend relationship to specify that one use case (extension) extends the behavior of another use case (base). A containment relationship supports the reuse of functionality in the use case model. In UML modeling, a Include relationship is a relationship in which one use case (base use case) contains the functionality of another use case (inclusion use case). Generalization relations are used in class diagrams, component diagrams, deployment diagrams, and use case diagrams to indicate that the child element accepts all the attributes, operations, and relationships defined in the parent element. It indicates that an actor can use the functionality of the business system.Ī generalization relation is a relationship in which one model element (child) is based on another model element (parent). An association is a relationship between an actor and a business use case. For example, the relationship between an actor and a use case illustrates that the actor can use certain functionality of the business system.Īn association is a relationship between two classifiers, such as an actor and use cases, that describes the cause of the relationship and the rules that govern it. Use case diagrams show use cases, actors, and the relationships between them. By reusing existing use cases using different types of relationships, the overall effort required to develop the system is reduced. The relationship between two use cases basically models the dependencies between two use cases. Use cases are also connected to each other in different kinds of relationships. In UML, relationships are connections between model elements.
