Discuss in detail the design concepts.

Abstraction

  • Functional abstraction
  • Data abstraction
  • Control abstraction

Information hiding

  • Each unit in the system hides the internal facts of its processing activities and modules communicate only through over defined interfaces.

Structure

  • It allows the breakup of a large system into smaller, more manageable units with well defined relationships to the other units in a system.
  • Network is the most common form of structure.

Hierarchical Structures/Structure Charts

  • It provides the structure of subroutines in a system, the data passed through routines, can be indicated on the arcs connecting routines.

Modularity

  • Modular system has a well-defined, manageable units with well defined interfaces among units.

Concurrency

  • Individual processes that can be activated concurrently if multiple processors are available.

Coupling and Cohesion

  • Data coupling - The data coupling is achievable by parameter passing or data interaction.
  • Control coupling - The modules share related control data in control coupling.
  • Common coupling - The global data is shared among modules.
  • Content coupling - Content coupling occurs when one module try to use of data or control information controlled in another module.
