Structural models and dynamic models.

Question 4

What is a design pattern in software development?

Answer 4

A way of reusing abstract knowledge about a problem and its solution.

Question 5

What is the first step in designing system architecture?

Answer 5

Understand the interactions between the systems and their environment.

Question 6

What is a system context model?

Answer 6

A structural model that demonstrates the other systems in the environment of the system being developed.

Question 7

What is the primary role of the Weather Data object in the Data Collection System?

Answer 7

To receive data from instruments and pass it to the Transmitter object.

Question 8

Why is object identification an iterative process?

Answer 8

It relies on the skill, experience, and domain knowledge of system designers and may not be correct on the first attempt.

Question 9

What is the significance of understanding system context in software design?

Answer 9

It helps to establish boundaries of the system and structure system functionality.

Question 10

What does software reuse involve in modern software development?

Answer 10

Constructing software by reusing existing components or systems.

Question 11

What is configuration management in software development?

Answer 11

The process of managing a changing software system during development.

Question 12

What common activities are included in object-oriented design processes?

Answer 12

Defining context, designing system architecture, identifying objects, and developing design models.

Question 13

What is an interaction model?

Answer 13

A dynamic model that shows how the system interacts with its environment as it is used.

Question 14

What type of objects may be identified in a weather station system?

Answer 14

Ground thermometer, anemometer, and barometer.

Question 15

What cost factors should be considered when reusing software components?

Answer 15

Time spent in searching, buying costs, adaptation costs, and integration costs.

Question 16

What is the goal of version management in configuration management?

Answer 16

To keep track of different versions of software components.

Question 17

What are the criteria for determining the level of detail in software design?

Answer 17

The type of system and whether using a plan-driven or agile approach.

Question 18

What are Host-Target Development environments?

Answer 18

Development on one computer (host) while executing on another (target).

Question 19

What are the two models of design modeling?

Answer 19

Static models and dynamic models.

Question 20

What are some examples of dynamic models?

Answer 20

Sequence models and state machine models.

Question 21

What is a use case in software design?

Answer 21

A description of how a user will interact with a system to achieve a goal.

Question 22

What are the benefits of using design patterns?

Answer 22

To capture best practices and good designs that can be reused.

Question 23

What does a structural model in design depict?

Answer 23

The static structure of the system in terms of object classes and relationships.

Question 24

What is included in the application domain for a weather station?

Answer 24

Hardware objects related to the instruments in the system.

Question 25

Why is software configuration important in software development?

Answer 25

It supports system integration by managing changes and tracking code access.
