Design Methods for Reactive Systems describes methods and techniques for the design of software systems-particularly reactive software systems that engage in stimulus-response behavior. Such systems, which include information systems, workflow management systems, systems for e-commerce, production control systems, and embedded software, increasingly embody design aspects previously considered alone-such as complex information processing, non-trivial behavior, and communication between different components-aspects traditionally treated separately by classic software design methodologies. But, a

The goal of this book is to present and compare various options one for systems architecture from two separate points of view. One, that of the information technology decision-maker who must choose a solution matching company business requirements, and secondly that of the systems architect who finds himself between the rock of changes in hardware and software technologies and the hard place of changing business needs.Different aspects of server architecture are presented, from databases designed for parallel architectures to high-availability systems, and touching en route on often- negl

Forms are everywhere on the web? For registration and communicating, for commerce and government. Good forms make for happier customers, better data, and reduced support costs. Bad forms fill your organization?s databases with inaccuracies and duplicates and can cause loss of potential consumers.Designing good forms is trickier than people think. Jarrett and Gaffney come to the rescue with Designing Forms that Work, clearly explaining exactly how to design great forms for the web. Liberally illustrated with full-color examples, it guides readers on how to define requirements, how to write questions that users will understand and want to answer, and how to deal with instructions, progress indicators and errors.

Targeted at Library and Information Science (LIS) professionals, this book concentrates on usability evaluation methods used to design usable and user-centered library websites. Aimed at the practitioner, it is a practical guide to methods that are used to gather information from potential users that shape the design of the website based on an interactive design process. From planning the study to writing the report, this book guides the reader through the process of usability evaluation using examples from the author's experience with usability evaluation of library interfaces. It describes u

Semantics in Business Systems begins with a description of what semantics are and how they affect business systems. It examines four main aspects of the application of semantics to systems, specifically: How do we infer meaning from unstructured information, how do application systems make meaning as they operate, how do practitioners uncover meaning in business settings, and how do we understand and communicate what we have deduced? This book illustrates how this applies to the future of application system development, especially how it informs and affects Web services and business rule- base
