Definitions

Definition 1

An architectural pattern that consist in decomposing a complex system in horizontal layers corresponding to distinct levels of abstraction that are orthogonal to the system vertical functional subdivisions.

This architectural patterns provides stability by confining changes to components and their interfaces, the possibility to substitute components, the reusability of components or even layers, and facilitates understanding of the overall system.

Examples
