Function-oriented Design

Software Design :-

There are two types of software design

1. Function oriented design
2. Object oriented design

1. Function oriented design :-

• It mainly in emphasis on what the system does.
• The system is compressed of many smaller subsystem known as function.
• Function oriented design is a method to software design where the model is decomposed into a set of instruction unit or module where its unit or module has a clearly defined function. Does the system is designed from functional group point.

The important function oriented technique is :

• Structural analysis
• Structural design

Structural analysis :- Structural analysis technique is based on the following essential underlying principles.

• Top down decomposition approach
• Divide and conquer method
• Graphical representation (DFD)
