Integrating Design Patterns into Forward Engineering Processes

摘要

Design patterns are reusable solutions to recurring problems that occur during software development. Most UML CASE tools do not assist in the integration and code generation of design patterns, this task is still left to the programmer. This paper describes a forward engineering process of UML static models which supports working with design patterns. This approach is based on the integration of semi-formal notations in UML with algebraic specifications. Transformations are supported by a library of reusable schemes and by a system of transformation rules which allow translating UML to algebraic specifications and object oriented code step by step. All the proposed transformations could be automated; they allow traceability and could be integrated into iterative and incremental software development process. Eiffel was chosen to show the feasibility of our approach.
