What are design patterns?

A design pattern is a solution to a common programing problem in software design. Patterns are not complete solutions but conceptual ideas for dealing with common issues. Patterns help communicate a common language among developers.

Keynotes:

  • What are design patterns?

    • A proven solution to a common issue in software design.

    • Patterns encourage reusable design strategies.

    • Common vocabulary and structure.

  • What design patterns are not?

    • An exact solution to a problem.

    • They don't replace good design strategy.

    • Can lead to inefficient solutions

  • What makes a pattern.

    • purpose

    • usefulness

    • applicability

    • acceptance (early stages proto-pattern)

  • Common Types of Patterns

    • Creational Patterns

    • Structural Patterns

    • Behavioral Patterns
