Abstraction

  • Functional abstraction
  • Data abstraction
  • Control abstraction

Information hiding

  • Every module in the system hides the internal details of its processing activities and modules communicate only by over defined interfaces.

Structure

  • It permits the decomposition of a large system into smaller, more manageable units with well explained relationships to the other units in a system.
  • Network is the most general form of structure.

Hierarchical Structures/Structure Charts

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

Modularity

  • Modular system consists of well-defined, manageable units with well defined interfaces between units.

Concurrency
