Abstract

Design patterns ease designing, understanding, andre-engineering software. Achieving a well-designedpiece of software requires a deep nderstanding and agood practice of design patterns. Understanding existing software relies on the ability to identify architectural forms resulting of the implementation of designpatterns. Maintaining software involves spotting placesthat can be improved by sing better design decisions,like those advocated by design patterns. Nevertheless,there is a lack of tools automatizing the use of designpatterns to achieve well-designed pieces of software, toidentify recurrent architectural forms, and to maintainsoftware. In this paper, we present a set of tools andtechniques to help OO software practitioners design,understand, and re-engineer a piece of software,sing design-patterns. A first prototype tool, PATTERNS-BOX, provides assistance in designing the architectureof a new piece of software, while a second prototypetool, PTIDEJ, identifies design patterns used in an existing one. These tools, in combination, support maintenance by highlighting defects in an existing design,and by suggesting and applying corrections based onwidely-accepted design patterns solutions.
