In software engineering, a design pattern is a general repeatable solution to a commonly occurring problem in software design. A design pattern isn’t a finished design that can be transformed directly into code. It is a description or template for how to solve a problem that can be used in many different situations.
There are three basic kinds of design patterns:
- creational
- structural
- behavioral
Creational patterns provide instantiation mechanisms, making it easier to create objects in a way that suits the situation.
Structural patterns generally deal with relationships between entities, making it easier for these entities to work together.
Behavioral patterns are used in communications between entities and make it easier and more flexible for these entities to communicate.
