物件導向軟體之架構(Object-Oriented Software Construction)探討

The moment-to-moment processing of information by the nervous system involves the propagation and interaction of electrical and chemical signals that are distributed in space and time. Biologically realistic modeling is needed to test hypotheses about the mechanisms that govern these signals and how nervous system function emerges from the operation of these mechanisms. The NEURON simulation program provides a powerful and flexible environment for implementing such models of individual neurons and small networks of neurons. It is particularly useful when membrane potential is nonuniform and membrane currents are complex. We present the basic ideas that would help informed users make the most efficient use of NEURON.

Domain-specific languages (DSLs) are languages tailored to a specific application domain. They offer substantial gains in expressiveness and ease of use compared with general-purpose programming languages in their domain of application. DSL development is hard, requiring both domain knowledge and language development expertise. Few people have both. Not surprisingly, the decision to develop a DSL is often postponed indefinitely, if considered at all, and most DSLs never get beyond the application library stage.Although many articles have been written on the development of particular DSLs, there is very limited literature on DSL development methodologies and many questions remain regarding when and how to develop a DSL. To aid the DSL developer, we identify patterns in the decision, analysis, design, and implementation phases of DSL development. Our patterns improve and extend earlier work on DSL design patterns. We also discuss domain analysis tools and language development systems that may help to speed up DSL development. Finally, we present a number of open problems.

The potential benefits of using models are significantly greater in software than in other engineering disciplines because of the potential for a seamless link between models and the systems they represent. Unfortunately, models have rarely produced anticipated benefits. The key lies in resolving pragmatic issues related to the artifacts and culture of the previous generation of software technologies.

From the Publisher:
Component Software: Beyond Object-Oriented Programming explains the technical foundations of this evolving technology and its importance in the software market place. It provides in-depth discussion of both the technical and the business issues to be considered, then moves on to suggest approaches for implementing component-oriented software production and the organizational requirements for success. The author draws on his own experience to offer tried-and-tested solutions to common problems and novel approaches to potential pitfalls. Anyone responsible for developing software strategy, evaluating new technologies, buying or building software will find Clemens Szyperski's objective and market-aware perspective of this new area invaluable.

Component Software: Beyond Object-Oriented Programming

Component software

Software has gone from obscurity to indispensability in less than fifty years. Although other industries have followed a similar trajectory, software and its supporting industry are different. In this book the authors explain, from a variety of perspectives, how software and the software industry are different--technologically, organizationally, and socially.The growing importance of software requires professionals in all fields to deal with both its technical and social aspects; therefore, users and producers of software need a common vocabulary to discuss software issues. In Software Ecosystem, Messerschmitt and Szyperski address the overlapping and related perspectives of technologists and nontechnologists. After an introductory chapter on technology, the book is organized around six points of view: users, and what they need software to accomplish for them; software engineers and developers, who translate the user's needs into program code; managers, who must orchestrate the resources, material and human, to operate the software; industrialists, who organize companies to produce and distribute software; policy experts and lawyers, who must resolve conflicts inside and outside the industry without discouraging growth and innovation; and economists, who offer insights into how the software market works. Each chapter considers not only the issues most relevant to that perspective but also relates those issues to the other perspectives as well. Nontechnologists will appreciate the context in which technology is discussed; technical professionals will gain more understanding of the social issues that should be considered in order to make software more useful and successful.

Software Ecosystem: Understanding an Indispensable Technology and Industry

Software components, if used properly, offer many software engineering benefits. Yet, they also pose many original challenges starting from quality assurance and ranging to architectural embedding and composability. In addition, the recent movement towards services, as well as the established world of objects, causes many to wonder what purpose components might have. This extended abstract summarizes the main points of my Frontiers of Software Practice (FOSP) talk at ICSE 2003. The topics covered aim to offer an end-to-end overview of what role components should play, where they should be used, and how this can be achieved Some key open problems are also pointed out.

Component technology - what, where, and how?

The open source movement is affecting software development products and processes. Software products benefit from reusable elements' increased availability and flexibility but might suffer from tighter coupling and more complex dependencies between reused components. The software development process is gaining from the widespread availability and use of sophisticated open source development platforms and tools, and the adoption of corresponding development and coding practices by the programmer community. In addition, code as literature is helping the meaningful education of programmers. However, process integration and the coevolution of multiple open source and proprietary projects are still open problems.
