Study Notes

What is Design?

Design is a meaningful representation of something to be built.
It's a process where requirements are translated into a blueprint for constructing software.
The blueprint gives a holistic view of the entire software.

Software Design Process?

It's the most creative part of the development process.
The Design Model is created from the Requirements Engineering Model.
This process involves diversification and convergence.

Software design work products

Different modules are designed.
Control relationships among modules are established.
Interfaces among the modules are specified.

Characteristics of good Design

Implements all explicit requirements.
Accommodates implicit requirements.
It should be readable and understandable.
It should provide a complete picture of the software.
