In software engineering, a design pattern is a general reusable solution to a commonly occurring problem within a given context in software design.

A design pattern is not a finished design that can be transformed directly into source or machine code.

It is a description or template for how to solve a problem that can be used in many different situations.

Patterns are formalized best practices that the programmer can use to solve common problems when designing an application or system.

Object-oriented design patterns typically show relationships and interactions between classes or objects, without specifying the final application classes or objects that are involved.

Patterns that imply object-orientation or, more generally, mutable state, are not as applicable in functional programming languages.
