Design Patterns

Creational Patterns give clear recipes for making objects in flexible ways, such as factories or builders, so your code stays easy to change and extend.

Structural Patterns show how to arrange classes like building blocks, wrapping or linking them neatly so you can reuse code without rewriting it.

Behavioural Patterns focus on how objects cooperate and pass work along, using techniques like commands or observers to reduce tight links and simplify testing.

Data Access Patterns guide you in reading and writing information through clear interfaces, hiding database details so storage can change without breaking the rest of the code.

Architectural Patterns draw the big picture of an application, setting rules for layers, modules, and data flow so teams can build reliable and maintainable systems.
