Architecture style-based calculi for non-functional properties

Engineers wield various "calculi" to help determine solutions to their problems, calculation tools varying in power from tensile strength tables to the differential calculus. A calculus is normally based on induction over an algebraic structure. Here the author explores how architecture styles can be used to describe such structures. An example calculus based on an "integration" style is presented, which is intended for use as a substyle of other architecture styles. Calculation rules in terms of the architectural elements can be used to compute non-functional attributes of artifacts described in such styles. Naturally, computerized support for calculi will help to automate the tasks of software engineers.
