IMPORTANCE OF SYSTEM DESIGN IN SOFTWARE DEVELOPMENT

Question 1

System design provides a detailed plan that developers must follow during the
implementation phase.

Answer 1

BLUEPRINT FOR DEVELOPMENT

Question 2

Many possible problems may be recognized and corrected during the design phase.

Answer 2

EARLY DETECTION ISSUES

Question 3

A well-designed system is easier to scale and maintain.

Answer 3

SCALABILITY AND MAINTENANCE

Question 4

A class should have only one reason to
change. It should have a single, well-defined responsibility. When a class has multiple responsibilities, changes to one can impact others.

Answer 4

SINGLE RESPONSIBILITY PRINCIPLE (SRP)

Question 5

Software entities (classes, modules,
functions, etc.) should be open for extension but closed for modification.

Answer 5

OPEN/CLOSED PRINCIPLE (OCP)

Question 6

Subtypes must be substitutable for their
base types without altering the correctness of the program.

Answer 6

LISKOV SUBSTITUTION PRINCIPLE (LSP)

Question 7

Client-specific interfaces are better than
one general-purpose interface. Clients
should not be forced to implement a function they do not need.

Answer 7

INTERFACE SEGREGATION PRINCIPLE (ISP)

Question 8

This principle states that our classes should depend upon interfaces or abstract classes instead of concrete classes and functions.

Answer 8

DEPENDENCY INVERSION PRINCIPLE (DIP)
