DESIGN PATTERN MATCHING

Procedia Technology, 2012

Since the Gang of Four "GoF" has published their book on Design Patterns, this concept has been greatly expanded and becomes a necessity in software development. The Number of new discovered Design Patterns grows rapidly making it difficult for software developers and others to choose between these amounts of patterns for the appropriate one. Hence, a tool that helps making decision in choosing and selecting suitable patterns to solve a specific problem becomes imperative. In this paper we present a support system for making decision in the choice of patterns. We present a Data Management System and initiate a modeling language for Design Patterns aiming to automate querybased search for patterns with respect to their textual part of the description.

– Design patterns and their catalogs are an important phenomenon in software development, and they present a challenge to modeling techniques and supporting tools. In this paper we identify and illustrate the problem in terms of the creational family and one of its members, the

Software design patterns have received much attention since the publication of Erich Gamma, et al.’s Design Patterns: Elements of Reusable Object-Oriented Design in 1995. From the twenty-three patterns presented in that study, the repertory has increased both in scope and in quantity. As of the year 2000, over 700 patterns have appeared in print, including not only design patterns for software, but analysis patterns and process patterns as well. Despite the attention that has been paid to design patterns in particular, a framework for understanding them has been limited to the problem and solution spaces within which the patterns are seen to operate. In this study, the design patterns of Gamma, et al. are considered as structures, structures that have both static and dynamic “shapes.” The study will argue that these shapes provide a more intelligible basis for the classification of patterns than the schemes normally employed and that they illuminate a level of cohesion among the patterns that is largely hidden in other accounts. This study aims both to provide a better classification for patterns and to form groups of patterns with related static and dynamic structures, groups that will lay the groundwork for future study and collapse what are now treated as distinct patterns into a small number of basic shapes.

We propose design patterns as a new mechanism for expressing object-oriented design experience. Design patterns identify, name, and abstract common themes in objectoriented design. They capture the intent behind a design by i d e n tifying objects, their collaborations, and the distribution of responsibilities. Design patterns play many roles in the object-oriented development process: they provide a common vocabulary for design, they reduce system complexity b y naming and de ning abstractions, they constitute a base of experience for building reusable software, and they act as building blocks from which more complex designs can be built. Design patterns can be considered reusable micro-architectures that contribute to an overall system architecture. We describe how to express and organize design patterns and introduce a catalog of design patterns. We also describe our experience in applying design patterns to the design of object-oriented systems.

To counter a single problem in a software design many reusable design patterns can be utilized. A designer can choose any design pattern by avoiding such design which can harm the concept of reusability. Design patterns are considered as one of the best practices to solve issue during the developmental stages. In the present paper an elaborative and analytical study is used to give the basic introductory knowledge regarding design patterns, their types and new developments in this field.

Design patterns are well-known design solutions that are reported to produce substantial benefits with respect to software quality. However, to our knowledge there are no scientific efforts on gathering information on software projects that use design patterns. This paper introduces a web repository of design patterns instances that have been used in open source projects. The usefulness of such a repository lies in the provision of a base of knowledge, where developers can identify reusable components and researchers can find a mined data set.

A pattern is a general and consensual solution to solve a problem frequently encountered in a particular context. Patterns systems are becoming more and more numerous. They offer product patterns or process patterns of varied range and cover (analysis, design or implementation patterns, and general, domain or enterprise patterns). New application development environments have been developed together with these pattern-oriented approaches. These tools address two kinds of actors: patterns engineers who specify patterns systems, and applications engineers who use these systems to specify information systems. Most of the existing development environments are made for applications engineers; they offer few functionalities allowing definition and organization of patterns systems. This paper presents AGAP, a development environment for defining and using patterns. Not only does AGAP address applications engineers, but it also allows patterns engineers to define patterns systems. The main goal of AGAP is to meet needs of the pattern and application engineer.

Design patterns represent a highly effective way to improve the quality of software system, due to its ability to capture the best practices and design knowledge; this enable software engineer to develop their applications. Unfortunately, choosing suitable patterns to specific design problems are difficult task for novice. Over the past years of research in the field of software engineering several conferences and workshops are focused on writing and publishing patterns; this increases the degree of challenges that face the developer in determining the suitable design patterns. This paper presents method to facilitate and assist the designers in selecting the suitable patterns for their problems. We propose a strategy method to obtain the appropriate recommendation.

Software design patterns describe proven solutions to recurring software design problems. Knowledge of these patterns increases designers' abilities, leads to cleaner and more easily maintained software, speeds up implementation and test, and helps programmers document and communicate their designs.
