What's the difference between Architectural Patterns and Architectural Styles?

Question

In Software Architecture - Foundations, Theory and Practice, I can find definitions for both. The problem is that I don\'t get what each one of them means in plain Engl

Answer 1

In very simple words:

• An architectural style

  Is a concept, theory (and how it's implemented it is up to you). It can also apply to outside of the software world.

  In example: REST (Representational State Transfer) is an architectural style built on certain principles using the current “Web” fundamentals.

• An architectural patterns

  Describes a solution at the software system (or module) level. In other words how it interacts each other e.g. view with model, and model with controller.

• A design patterns

  Is a solution at the core level, it talks about classes, functions and how actually the logic flows.
