Architectural and Design Patterns - 101
===
> A **pattern** is a recurring solution to a recurring problem. In the case of **Architectural Patterns**, they solve the problems related to the Architectural Style. For example, “what classes will we have and how will they interact, in order to implement a system with a specific set of layers“, or “what high-level modules will have in our Service-Oriented Architecture and how will they communicate“, or “how many tiers will our Client-server Architecture have“.
> **Architectural Patterns** have an extensive impact on the code base, most often impacting the whole application either horizontally (ie. how to structure the code inside a layer) or vertically (ie. how a request is processed from the outer layers into the inner layers and back).
> **Design Patterns** 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 They differ from Architectural Patterns in their scope, they are more localised and have less impact on the code base.
