Problem-Oriented Documentation of Design Patterns

چکیده
In order to retrieve, select and apply design patterns in a tool-supported way, we suggest to construct and document a problemcontext pattern that reflects the essence of the problems that the design pattern is meant to solve. In our approach, software engineers can choose examples of source code or UML models from the special domains that they are experts in. We present a method that enables software engineers to describe the transformation from a problem-bearing source model to an appropriate solution model. Afterwards, the inverse of that transformation is applied to the UML solution model of the existing design pattern, resulting in an abstract problem-context pattern. This pattern can then be stored together with the solution pattern in a pattern library. The method is illustrated by deriving a problem-context pattern for the Observer design pattern.

An Empirical Investigation of Methods, for Teaching Design Patterns within, Object-Oriented Frameworks
Design patterns have become an important part of modern object-oriented design. It is necessary to evaluate and compare the effectiveness of different methods of pedagogical documentation in teaching design patterns. We compared patterns-style documentation with minimalist documentation. Patterns style disagrees with minimalism in that contextual information is not minimal it usually contains i...
متن کاملDescribing Framework Architectures: more than Design Patterns
In this paper we argue for the necessity of an architectural description of a framework. We then analyze why design patterns on their own are insu cient for such a description and propose that a variety of complementary forms of documentation are needed to address the requirements of an architectural description. We claim that traditional artifacts of domain analysis and object-oriented design ...
متن کاملA goal-oriented approach for representing and using design patterns
Design patterns are known as proven solutions to recurring design problems. The role of pattern documentation format is to transfer experience thus making pattern employment a viable technique. This research line proposes a goal-oriented pattern documentation that highlights decision-relevant information. The contribution of this paper is twofold. First, it presents a semi-structural visual not...
متن کاملPrivacy Design Patterns and Anti-Patterns Patterns Misapplied and Unintended Consequences
One critique of Privacy-by-Design has focused on its lack of concrete guidance for implementation. We have proposed privacy design patterns (drawing from architectural design patterns and object-oriented programming design patterns) as documentation that can be more directly applicable and have established a site to coordinate collaborative development of such patterns. We argue that patterns —...
متن کاملPatterns for Documenting Frameworks – Part I
Good design and implementation are necessary but not sufficient pre-requisites for the successful reuse of object-oriented frameworks. Although not always recognized, good documentation is crucial for effective framework reuse, and comes with many issues. Defining and writing good quality documentation for a framework is often hard, costly, and tiresome, especially when not aware of its key pro...
متن کاملEvolution Support by Homogeneously Documenting Patterns, Aspects and Traces
The evolution of complex software systems is promoted by software engineering principles and techniques like separation of concerns, encapsulation, stepwise refinement, and reusability of design solutions. Design patterns capture the expertise for reusable design solutions. Aspect-oriented programming is a methodology that enables the modularization of cross-cutting concerns. Traceability links...
