DesignPatterns

Intro

• A design pattern systematically names, explains, and evaluates an important and recurring design problem and its solution.
• Patterns support reuse of software architecture and design.
• They give software engineers a vocabulary with which to describe their designs.
• Patterns solve design problems such as:
  • Finding appropriate classes to solve a problem.
  • Determining how abstract or how concrete a class should be.
  • Specifying interfaces of classes, architectures, and binary components.
  • Designing for change.
• Patterns are not code-reuse they are experience reuse !
