Chapter 1, Problem 3RQ

Explanation of Solution

Decomposition:

• Decomposition is the process of breaking a system into smaller components.
• These components can be systems or subsystems and be again broken down into its components.
• It forms smaller and less complex pieces and is easier to understand than larger complicated pieces.
• Decomposition is thus a technique that allows system analyst to follow the below steps:
  • Break a system into small, manageable and understandable subsystems...

Explanation of Solution

Coupling:

• Coupling is a property in which subsystems are dependent on each other.
• If one subsystem is highly dependent on another subsystem, and if this subsystem fails then the other subsystem which is dependent will also fail or they will have functioning problems...

Explanation of Solution

Cohesion:

• Cohesion is a property in which the subsystem performs a single function.
• It actually refers to the degree to which elements inside a module belong together.
• High cohesion correlates with low coupling and low cohes...
