Ontwikkelingspatronen

Ontwikkelingspatronen, also known as development patterns, are recurring solutions to common problems in software development. They represent best practices used by experienced object-oriented software developers. These patterns are typically described at a high level of abstraction and can be applied to various programming languages and paradigms. The concept of development patterns was popularized by the book "Design Patterns: Elements of Reusable Object-Oriented Software" by Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides, often referred to as the "Gang of Four" (GoF).

Development patterns are categorized into three main groups: creational, structural, and behavioral. Creational patterns deal with object creation mechanisms, trying to create objects in a manner suitable to the situation. Examples include Singleton, Factory Method, and Abstract Factory. Structural patterns concern class and object composition, aiming to ensure that if one part of a system changes, the entire system does not need to. Examples include Adapter, Decorator, and Proxy. Behavioral patterns are concerned with algorithms and the assignment of responsibilities between objects. Examples include Observer, Strategy, and Command.

The use of development patterns promotes code reuse, reduces complexity, and improves maintainability. They provide a shared vocabulary for developers, making it easier to communicate and collaborate. However, it's important to note that not all problems can be solved with patterns, and overuse or misuse of patterns can lead to unnecessary complexity. Therefore, patterns should be applied judiciously and with a deep understanding of the problem at hand.
