Decomposition and Interfaces Revisited

Abstraction and hierarchical decomposition are key principles for mastering complexity in science and engineering. In Software Engineering, the interfaces that result from the application of those principles play a crucial role, particularly when building large and complex systems. This article revisits general principles behind abstraction and decomposition and presents a collection of fundamental principles and design goals to guide the modularization of a system and the definition of interfaces.
