Modularity

• What is Software Modularity
• A Modular System is a system structured into
  highly independent abstractions called modules.
• Modularity is important for both design and
  implementation phases.
• What is a module
• A software entity encapsulating the
  representation of an
• Abstraction
• A work assignment for a programmer or group of
  programmers.

Modular Design Methodology

• Modular decomposition
• Modular Composibility
• Modular Understandability
• Modular continuity
• Modular protection

Principles of Modular Design

• Linguistic modular units
• Few interfaces
• Small Interfaces
• Explicit Interfaces
• Information Hiding

Cohesion Coupling

• Cohesion
• Cohesion means that a certain module performs
  a set of closely related actions.
• Coupling
• It is the degree to which each program module
  relies on each other module.
