Week 3

What is the difference between a UML actor and a UML profile?

A UML actor models an entity that interacts with a system object and a UML profile provides a way of extending an existing model to other domains or platforms.

What is the difference between a passive state and an active state in UML state diagrams?

A passive state is simply the current values assigned to an object's attributes whereas an active state of an object indicates the status of the object as it undergoes a continuing transformation or processing.

Which of the following statement is the BEST to answer the following question: Requirements gathering necessitates a collaborative approach of sharing information. Why is this such a difficult aspect of the project development?

Every person involved in the project will bring their own viewpoint to the solution. Dealing with the different personalities, their way of expressing themselves and their expectations can cause conflict. Working to deescalate conflict but still achieve the desired outcome can take skill.

How does the UML model use "sequence diagrams"?

For behavioral modeling.

Fill in the blank to this question. The __________ encompasses the data that flow into the system, the data that flow out of the system, and the data stores that collect and organize the data that are maintained permanently.

Information domain

Which of the following statements BEST describes what requirements engineering means?

Requirements engineering is the term for the broad spectrum of tasks and techniques that lead to an understanding of requirements.

Which of the following BEST explains the use of the UML activity diagrams?

The UML activity diagram supplements the use case by providing a graphical representation of the flow of interaction within a specific scenario.

Which of the following statements BEST describes the term "elaboration" in relation to software engineering?

The elaboration task focuses on developing a refined requirements model that identifies various aspects of software function, behavior, and information.

Use cases within the software engineering project tells a story about how the end user interacts with the system. What would be the first step in developing a use case?

The first step would be to define the actors.

Which statement BEST describes an "analysis model"?

The intent of the analysis model is to provide a description of the required informational, functional, and behavioral domains for a computer-based system.

Which of the following could not be a potential class?

Time of entry

Of the following statements, which is the BEST answer to the following question: What might cause a situation to occur where it becomes necessary to negotiate the requirements of the software engineering activities?
