The Design Patterns Portal

Design Patterns, also known as software design patterns, are a reusable solution to a software engineering problem. Design patterns give the developer a starting point and can help improve efficiency, readability, scalability, and maintainability. By starting with a commonly known design pattern, the software becomes easier to read and understand for other developers familiar with the design pattern.

	Basic Design Patterns Basic design patterns deal with simple patterns of at least one loop, or multiple loops with communication happening in just one direction between the loops. Single Loop State Machine Event Handler Multiple Loop Master/Slave Producer/Consumer	Intermediate Design Patterns Intermediate design patterns deal with multi-loop patterns usually implementing a messaging scheme communicating bi-directional between the loops.
