Explain in detail the design concepts.

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

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