43 a diagram that shows the messages between an actor and the system is called a(n) _______.

Actions are performed with lines that extend between these lifelines. When an action line is connected to a lifeline it shows the interaction between the actor or system. Messages will often appear at the top or bottom of a system sequence diagram to illustrate the action in detail. 26. Answer : (d) Reason: Component diagram models the physical components of the system. 27. Answer : (c) Reason: Stereo types represent the built-in extensibility mechanism of UML. 28. Answer : (a) Reason: Noun-Phrase Method and (RC Approach are used to identify classes.

_ diagrams depict the interaction between an actor and the system fro a use case scenario System Sequence __ diagrams graphically depict how objects interact with each other via messages in execution of use case or operation.

A diagram that shows the messages between an actor and the system is called a(n) _______.

A system sequence diagram is, as the name suggests, a type of sequence diagram in UML. These charts show the details of events that are generated by actors from outside the system. A use case diagramis ';a diagram that shows the relationshipsamong actors and use cases within a system. 'Use case diagrams are often used to: UML is the modeling toolkit that you can use to build your diagrams. Use cases are represented with a labeled oval shape. Stick figures represent actors in the process, and the actor's participation in the system is modeled with a line between the actor and use case. To depict the system boundary, draw a box around the use case itself. 15. In a sequence diagram, a(n) message is identified by a line showing direction that runs between two objects. 16. The focus indicates when an object sends or receives a message. 17. A(n) state transition diagram shows how an object changes from one state to another, depending on events that affect the object. 18.

Reason: Gane and Sarson, Shlaer Mellor and Extreme Programming are not object oriented Methodologies. 292. Answer : (a) Reason: Use Case is a construct that helps analysts to work with users to determine system usage. 293. Answer : (c) Reason: 1..2 represents 1 or 2 but not 1-2. Association Between Actor and Use Case. This one is straightforward and present in every use case diagram. Few things to note. An actor must be associated with at least one use case. An actor can be associated with multiple use cases. Multiple actors can be associated with a single use case. UML Sequence Diagrams are interaction diagrams that detail how operations are carried out. They capture the interaction between objects in the context of a collaboration. Sequence Diagrams are time focus and they show the order of the interaction visually by using the vertical axis of the diagram to represent time what messages are sent and when. Collaboration diagrams (known as Communication Diagram in UML 2.x) are used to show how objects interact to perform the behavior of a particular use case, or a part of a use case.Along with sequence diagrams, collaboration are used by designers to define and clarify the roles of the objects that perform a particular flow of events of a use case.

• Sequence diagram: an “interaction diagram” that models a single scenario executing in a system • 2nd most used UML diagram (behind class diagram) • Shows what messages are sent and when • Relating UML diagrams to other design artifacts: • CRC cards → class diagrams • Use cases → sequence diagrams cases describe interactions between a system and external actors; sequence diagrams add more information to these by showing interactions between system objects. • Structural models show the organization and architecture of a system. Class diagrams are used to define the static structure of classes in a system and their associations. Which of the following best describes a use case ? A. It is text describing in detail one flow of events through a real situation. B. it is the system specification problem statement. C. it is text which describes the dialogue between actors and the system. D. a diagram drawn to illustrate how cases and actors interact by sending stimuli to one ... a) Use case diagram is a dynamic model of interaction between actors and product in a use case b) Use case Description is a static model of use case supported by a product c) All of the mentioned d) None of the mentioned Answer:D. 14. A UML diagram that facilitates requirements gathering and interacts between system and external users, is called as

Use Case Descriptions • actors - something with a behavior or role, e.g., a person, another system, organization. • scenario - a specific sequence of actions and interactions between actors and the system, a.k.a. a use case instance • use case - a collection of related success and failure scenarios, describing actors using the system to

Contents of Sequence Diagrams. You can have objects and actor instances in sequence diagrams, together with messages describing how they interact. The diagram describes what takes place in the participating objects, in terms of activations, and how the objects communicate by sending messages to one another.

Communication Diagram at a Glance. In the example of the notation for a communication diagram, objects (actors in use cases) are represented by rectangles. In the example (generic communication diagram): The objects are Object1, Object2, Object..., ObjectN-1 ..., and ObjectN. Messages passed between objects are represented by labeled arrows that start with the sending object (actor) and end with the receiving object.

The collaboration diagram is used to show the relationship between the objects in a system. Both the sequence and the collaboration diagrams represent the same information but differently. Instead of showing the flow of messages, it depicts the architecture of the object residing in the system as it is based on object-oriented programming.
