Modularity in continually evolving systems

Abstract

The design of a continually-evolving system deteriorates in proportion to the frequency of evolution as much as the complexity of evolution. Here we introduce a design paradigm, Temporal Control Flow Rule-based Architecture (TeCFRA), with a vision to support dynamic evolution in software architecture. TeCFRA provides this support especially when new rules for existing business processes co-exist with old rules. TeCFRA also strives to attain a higher precision level in change-impact analysis.
