DISPONIBILIDADE IMEDIATA

 Computer-aided design syst,ems have become a big business. Advances in technology have made it commercially feasible to place a powerful engineering workstation on every designer''s desk. A major selling point for these workstations is the computer aided design software they provide, rather than the actual hardware. The trade magazines are full of advertisements promising full menu design systems, complete with an integrated database (preferably "relational"). What does it all mean? This book focuses on the critical issues of managing the information about a large design project. While undeniably one of the most important areas of CAD, it is also one of the least understood. Merely glueing a database system to a set of existing tools is not a solution. Several additional system components must be built to create a true design management system. These are described in this book. The book has been written from the viewpoint of how and when to apply database technology to the problems encountered by builders of computer-aided design systems. Design systems provide an excellent environment for discovering how far we can generalize the existing database concepts for non-commercial applications. This has emerged as a major new challenge for database system research. We have attem pted to avoid a "database egocentric" view by pointing out where existing database technology is inappropriate for design systems, at least given the current state of the database art.

Design Of Office Information Systems

 The goal of this book is to present a framework within which the myriad of office technologies and office systems design techniques can be better understood. There are a number of office books which deal with the social/organizational aspects of office automation or with office equip ment introduction strategies. This book differs from those in that it is written by technical computer people for technical computer people. As such, it assumes a general computer literacy and contains a technical emphasis with a social fiber woven in. Besides the framework, we also present the current state of office primitives, office tools, and office tech nology. We cover relevant work on-going by international standards bod ies, and we discuss the concepts that are emerging (or which we feel will be emerging) from universities and industrial research laboratories. Office technologies and techniques are classified as personal environment aids versus communal environment aids. We now fully realize how difficult it is to write a coherent book within this fuzzy, interdisciplinary, rapidly changing field. Concepts have been stressed wherever possible; there are some sub-areas where the generaliz ing concepts have not yet emerged. We also realize the potential danger of obsolescense. We have tried to combate this somewhat by the presen tation of concepts, generic tool design, and emphasizing our framework. This book is not a substitute for reading of the current periodical litera ture - that is where the most timely information lies.

Logic Programming And Databases

de Georg Gottlob, Letizia Tanca e Stefano Ceri

DISPONIBILIDADE IMEDIATA

 The topic of logic programming and databases. has gained in creasing interest in recent years. Several events have marked the rapid evolution of this field: the selection, by the Japanese Fifth Generation Project, of Prolog and of the relational data model as the basis for the development of new machine archi tectures; the focusing of research in database theory on logic queries and on recursive query processing; and the pragmatic, application-oriented development of expert database systems and of knowledge-base systems. As a result, an enormous amount of work has been produced in the recent literature, coupled with the spontaneous growth of several advanced projects in this area. The goal of this book is to present a systematic overview of a rapidly evolving discipline, which is presently not described with the same approach in other books. We intend to introduce stu dents and researchers to this new discipline; thus we use a plain, tutorial style, and complement the description of algorithms with examples and exercises. We attempt to achieve a balance be tween theoretical foundations and technological issues; thus we present a careful introduction to the new language Datalog, but we also focus on the efficient interfacing of logic programming formalisms (such as Prolog and Datalog) with large databases.
