Analysis model

Question 7

What are the 7 distinct requirements of engineering?

Answer 7

1. Inception -ask a set of questions that establish basic understanding of the problem
2. Elicitation- requirements from all stakeholders such as scope, objectives, boundaries etc.
3. Elaboration- inception and elicitation information is expanded and refined. Creation and refinement of user scenarios.
4. Negotiation- agree on a deliverable system that is realistic for developers and customers
5. Specification- can be any one or more of the following: written document, set of models , prototype, etc
6. Validation- a review mechanism that looks for errors in content or interpretations
7. Requirements management- identify, control, and track requirements and changes to requirements.

Question 8

Answer 8

Can be described as a quality attribute, performance attribute, security attribute, or general system constraint.

Question 9

A ______ describes a thread of usage for a system

Answer 9

Scenario

Question 10

At a technical level, software engineering begins with a series of modeling tasks that lead to a
specification of requirements and a design representation for the software to be built.

Answer 10

True

Question 11

The requirements model—actually a set of models—is the first technical representation of a
system.

Answer 11

True

Question 12

________ ______ results in the specification of software’s operational characteristics,
indicates software’s interface with other system elements, and establishes constraints that software
must meet.

Answer 12

Requirements analysis

Question 13

. ________ _________ allows you (regardless of whether you’re called a software engineer, an
analyst, or a modeler) to elaborate on basic requirements established during the inception,
elicitation, and negotiation tasks that are part of requirements engineering

Answer 13

Requirements analysis

Question 14

____ The ______ _____ bridges the gap between a system- level description … and a software
design…

Answer 14

analysis model

Question 15

All elements of the _____ _______ will be directly traceable to parts of the design model.

Answer 15

requirements model

Question 16

_________ ______ depict software requirements from the user’s point of view.

Answer 16

Scenario-based models

Question 17

The objective of _______ _______ is to create a variety of representations that describe
what the customer requires, establish a basis for the creation of software design, and define a set of
requirements that can be validated once the software is built.

Answer 17

requirements modeling

Question 18

The _______ ______ bridges the gap between a system-level description that describes
overall system and business functionality and a software design that describes the software’s
application architecture, user interface, and component-level structure.

Answer 18

requirements model

Question 19

What are the 5 requirements modeling action types of models? What is the purpose of
each?

Answer 19

Scenario-based
— system from the user’s point of view
Data
— shows how data are transformed inside the system
Class-oriented
— defines objects, attributes, and relationships
Flow-oriented
— shows how data are transformed inside the system
Behavioral
— show the impact of events on the system states

Question 20

In class-based methods, what are the 3 class types? Briefly define or state the use for each.

Answer 20

Entity classes, —-also called model or business classes, are extracted directly from the statement of the problem (e.g.,FloorPlan and Sensor).
Boundary classes —- are used to create the interface (e.g.,
interactive screen or printed reports) that the user sees and interacts with as the software is used.
Controller classes — manage a “unit of work” [UML03] from start to finish. That is, controller classes can be designed to manage:
—– the creation or update of entity objects;

Question 21

The ________ ______ indicates how software will respond to external events or stimuli.

Answer 21

behavioral model

Question 22

In general, an ____ occurs whenever the system and an actor exchange information.

Answer 22

event

Question 23

An event is not the _______ that has been exchanged, but rather the fact that information
has been exchanged.

Answer 23

information

Question 24

What are two states of a class? Define each

Answer 24

A passive state —— is simply the current status of all an
object’s attributes.
The active state —— of an object indicates the current
status of the object as it undergoes a continuing
transformation or processing.

Question 25

What are the Requirements Modeling Output for WebApps?

Answer 25

1. Content model —identifies the full spectrum of content
   to be provided by the application. Content includes text,
   graphics and images, video, and audio data.
2. Interaction model —describes the manner in which
   users interact with the app.
3. Functional model —defines the operations that will be
   applied to manipulate content and describes other
   processing functions that are independent of content but
   necessary to the end user.
4. Navigation model —defines the overall navigation
   strategy for the app.
5. Configuration model —describes the environment and
   infrastructure in which the app resides.
