Pattern-based exploration of design alternatives for the evolution of software architectures
We propose a pattern-based software development method comprising analysis (using problem frames) and design (using architectural and design patterns), from which especially evolving systems benefit. Evolution operators guide a pattern-based transformation procedure, including re-engineering tasks for adjusting a given software architecture to meet new system demands. Through application of these operators, relations between analysis and design documents are explored systematically for accomplishing desired software modi. cations. This allows for reusing development documents to a large extent, even when the application environment and the requirements change.
