Patterns of home life: Informing design for domestic environments

This paper considers how we may provide support for the development of general design principles in domestic environments. In particular, we examine the potential for usingdesign patterns as a means of presenting ethnographic material and outlining design solutions. The paper reports on the development of an initial pattern language based on our studies of a number of domestic, environments and offers a general structure for presenting these patterns. Finally, we briefly reflect on our experiences of developing an on-line set of patterns for this class of environment.

Principles versus patterns

Early in the history of programming, brilliant people realized that every good software system has some desirable properties: It should be extensible; parts of it should be modifiable without major impact on other parts; and so on. Because of the Feigenbaum Bottleneck, it is very hard to describe precise, step-by-step instructions to build systems with such properties. It is easier to articulate the desirable properties in the form of design principles. Over the years, the wealth of knowledge accumulated as design principles has reached a critical mass. Entire books are now dedicated to the subject. Still, despite this body of knowledge, design remains difficult. A major problem is that principles are ambiguous and not very constructive. In more recent times, design patterns have emerged as a valid alternative to the principles-driven approach. If principles represent the “say-what” approach to design, patterns are the “show-how” way     

An approach for pattern oriented software development based on a design handbook

In many mature engineering disciplines, reuse of available design knowledge is helped by the presence of handbooks. These handbooks record the details of existing system components and help in the process of evaluating design alternatives while building new systems. In recent times, design patterns have been identified as fundamental components of an object oriented design. However, they are presented in a format that may not be best suited for systematic selection and use while evaluating design alternatives. This paper provides a procedure to construct a handbook based on design patterns. This handbook helps designers in methodical selection of design patterns. The construction of the handbook is based on the identification of a set of key attributes of a design pattern and quantification of these attributes using the principles of measurement theory. A new methodology for object oriented design which consults the handbook during the design process is also introduced. The proposed methodology along with the handbook helps in evaluating different design alternatives. This revised version was published online in June 2006 with corrections to the Cover Date.     

Towards pattern‐based architectures for event processing systems

Recently, event processing (EP) has gained considerable attention as an individual discipline in computer science. From a software engineering perspective, EP systems still lack the maturity of well‐established software architectures. For the development of industrial EP systems, generally accepted software architectures based on proven design patterns and principles are still missing. In this article, we introduce a catalog of design patterns that supports the development of event‐driven architectures (EDAs) and complex EP systems. The design principles originate from experiences reported in publications as well as from our own experiences in building EP systems with industrial and academic partners. We present several patterns on different layers of abstractions that define the overall structure as well as the building blocks for EP systems. Architectural patterns that determine the top‐level structure of an EDA can be distinguished from design patterns that specify the basic mechanisms of EP. The practical application of the catalog of patterns is described by the pattern‐based design of a sample EDA for a sensor‐based energy control system. Finally, we propose a coherent and general reference architecture for EP derived from the proposed patterns.Copyright © 2013 John Wiley & Sons, Ltd.     

A graph mining approach for detecting identical design structures in object-oriented design models

The object-oriented approach has been the most popular software design methodology for the past twenty-five years. Several design patterns and principles are defined to improve the design quality of object-oriented software systems. In addition, designers can use unique design motifs that are designed for the specific application domains. Another commonly used technique is cloning and modifying some parts of the software while creating new modules. Therefore, object-oriented programs can include many identical design structures. This work proposes a sub-graph mining-based approach for detecting identical design structures in object-oriented systems. By identifying and analyzing these structures, we can obtain useful information about the design, such as commonly-used design patterns, most frequent design defects, domain-specific patterns, and reused design clones, which could help developers to improve their knowledge about the software architecture. Furthermore, problematic parts of frequent identical design structures are appropriate refactoring opportunities because they affect multiple areas of the architecture. Experiments with several open-source and industrial projects show that we can successfully find many identical design structures within a project (intra-project) and between different projects (inter-project). We observe that usually most of the detected identical structures are an implementation of common design patterns; however, we also detect various anti-patterns, domain-specific patterns, reused design parts and design-level clones.     

A framework for epistemological analysis in empirical (laboratory and field) studies

In their search for generalizable behavioral patterns and design principles, cognitive field researchers should reflect on the epistemological limitations of empirical studies. In this paper we describe a framework for epistemological analysis that can help serve this purpose and discuss its application to two prototypical cases of cognitive engineering research: laboratory experiments and field studies. The framework examines two, often implicit, processes in empirical research: the abstraction from empirical data and the substantiation of theoretical constructs and principles. By explicitly considering these two processes in several systematic steps, we can gain appreciation for the epistemological contribution of empirical studies to cognitive engineering research. The framework and its application also provide guidance to such important issues as generalizability of results and external validity. Possible applications of this research include providing guidance to researchers and practitioners in evaluating design principles or conducting field studies.     

Avoiding repetition [software design]

Software design is not easy-not easy to do, teach, or evaluate. Much of software education these days is about products and APIs, yet much of these are transient, whereas good design is eternal, if only we could figure out what good design is. The author has been struck by one of the underlying principles that leads to better designs: remove duplication. The principle is simple: say anything in your program only once. Stated blandly like that, it hardly bears saying. Yet identifying and removing repetition can lead to many interesting consequences. The author looks at a simple case of subroutine calls. He considers the benefits of design patterns
