Software Architecture definitions

Perry and Wolf, ’92 (aspects):→“Architecture is concerned with the selection of architectural elements, their interactions, and the constraints on those elements and their interactions necessary to provide a framework in which to satisfy the requirements and serve as a basis for the design.”

→Elements are divided into processing elements, data elements and connection elements

Garlan and Shaw, ’93 (elements):→ Architecture for a specific system may be captured as “a collection of computational components - or simply components - together with a description of the interactions between these components - the connectors –”
