An Architecture is…

• set of significant decisions about the organization of a software system, • selection of the structural elements and their interfaces by which the

system is composed, • behavior of the structural elements as specified in the collaborations

among those elements, • composition of these structural and behavioral elements into

progressively larger subsystems, • architectural style that guides this organization (i.e. these elements

and their interfaces, their collaborations, and their composition).
