For several terms at Cambridge in 1939, Ludwig Wittgenstein lectured on the philosophical foundations of mathematics. A lecture class taught by Wittgenstein, however, hardly resembled a lecture. He sat on a chair in the middle of the room, with some of the class sitting in chairs, some on the floor. He never used notes. He paused frequently, sometimes for several minutes, while he puzzled out a problem. He often asked his listeners questions and reacted to their replies. Many meetings were largely conversation. These lectures were attended by, among others, D. A. T. Gasking, J. N. Findlay, Stephen Toulmin, Alan Turing, G. H. von Wright, R. G. Bosanquet, Norman Malcolm, Rush Rhees, and Yorick Smythies. Notes taken by these last four are the basis for the thirty-one lectures in this book. The lectures covered such topics as the nature of mathematics, the distinctions between mathematical and everyday languages, the truth of mathematical propositions, consistency and contradiction in formal systems, the logicism of Frege and Russell, Platonism, identity, negation, and necessary truth. The mathematical examples used are nearly always elementary.

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- based approaches, and how semantics will play out with XML and the semantic Web. The book also contains a quick reference guide to related terms and technologies. It is part of Morgan Kaufmann's series of Savvy Manager's Guides. * Presents an easy and enjoyable introduction to semantics in the context of business IT systems. * Articulates the business value of semantics, while providing relevant introductory technical background. * Describes the semantic underpinnings of data modeling, business rules, enterprise integration, and Web services. * Contains a handy quick-reference guide to technologies and terminology. * For more information, links, and discussions, go to www.savvymanagers.com.

A thorough update to the industry standard for designing, developing, and deploying data warehouse and business intelligence systems The world of data warehousing has changed remarkably since the first edition of The Data Warehouse Lifecycle Toolkit was published in 1998. In that time, the data warehouse industry has reached full maturity and acceptance, hardware and software have made staggering advances, and the techniques promoted in the premiere edition of this book have been adopted by nearly all data warehouse vendors and practitioners. In addition, the term "business intelligence" emerged to reflect the mission of the data warehouse: wrangling the data out of source systems, cleaning it, and delivering it to add value to the business. Ralph Kimball and his colleagues have refined the original set of Lifecycle methods and techniques based on their consulting and training experience. The authors understand first-hand that a data warehousing/business intelligence (DW/BI) system needs to change as fast as its surrounding organization evolves. To that end, they walk you through the detailed steps of designing, developing, and deploying a DW/BI system. You'll learn to create adaptable systems that deliver data and analyses to business users so they can make better business decisions.

Latin names ? frequently unpronounceable, all too often wrong and always a tiny puzzle to unravel ? have been annoying the layman since they first became formalised as scientific terms in the eighteenth century. Why on earth has the entirely land-loving Eastern Mole been named Scalopus aquaticus, or the Oxford Ragwort been called Senecio squalidus ? 'dirty old man'? What were naturalists thinking when they called a beetle Agra katewinsletae, a genus of fish Batman, and a Trilobite Han solo? Why is zoology replete with names such as Chloris chloris chloris (the greenfinch), and Gorilla gorilla gorilla (a species of, well gorilla)? The Naming of the Shrew will unveil these mysteries, exploring the history, celebrating their poetic nature and revealing how naturalists sometimes get things so terribly wrong. With wonderfully witty style and captivating narrative, this book will make you see Latin names in a whole new light.
