Book Description
A little more than a decade ago my colleagues and I faced the necessity for providing a database management system which might commonly serve a number of different types of computer aided design applications at different manufacturing enterprises. We evaluated some wellknown cases of conceptual models and commercially available DBMSs, and found none fuHy meeting the requirements. Yet the analysis of them led us to the development of what we named the Logical Structure Management System (LMS). Syntactically the LMS language is somewhat similar to ALPHA by E. F. Codd. The underly ing conceptual model is entirely different from that of the relational model, however. LMS has been since put into practical use, meanwhile a further ef fort in search of asound theoretical base and a concrete linguistic framework for true product modeling together with comparative studies of various ap proaches has been made. Here, the term product modeling is used to signify the construction of informational models of design objects and design pro cesses in which it must be possible to include not a fixed set of attributes and relations, such as geometry, physical properties, part-of hierarchy, etc. , but whatever aspects of design designers may desire to be included. The purpose of this book is to present the major results of the said effort, which are primarily of a theoretical or conceptual nature. Following the intro duction (Chap.

Book Description
Materials Information for CAD/CAM addresses the problem of designing databases, expert system, communication systems, and decision support aids that can be integrated with manual and software-supported tasks in design and manufacture, in CAD and CAM. This book covers tasks of materials selection, materials process simulation, and materials modelling that involve access to materials identification or property information. Organized into eight chapters, this book begins with an overview of the use of materials information in engineering design and manufacture. This text then explains how computerized CAD/CAM systems change the ways in which this information has been effectively used. Other chapters consider the organizational and technical aspects of data interchange in general. This book discusses as well the requirements in representing materials information in databases. The final chapter deals with integrated design environments with respects to their capabilities for utilizing materials information. This book is intended to be suitable for anyone who is planning the construction, management, or use of any kind of engineering materials property information system.

Book Description
To understand what we know and be aware of what is to be known is a necessary approach to treating CAD/CAM issues. The challenge for all of us interested in CAD/CAM and engineering data handling is to under stand what we know and what we need to know about today's and tomorrow's technology, to track the explosive development of our field and its broadening range of applications, to sort through the details which compete for our attention, and to perceive underlying trends. A key development in the past year was the rapid and widespread acceptance by all user segments of personal computer-based CAD/CAM workstations, coupled with widespread use of software packages, both those developed for PC-based workstations and others converted from main frame and mini systems for use on PC-based or 32-bit workstations. If this trend continues for a few more years, as much as 900/0 of all design work may be accomplished on advanced versions of PC-based workstations. Many software systems vendors unknown until recently to the PC-based CAD/CAM community have now come to dominate the market-companies such as Autodesk, Chessell-Robocom, Future Net, T&W Systems, P-CAD, Cascade, 4-D Graphics, CADAM, Wang & Hornbuckle, and more than 20 other companies who sell PC-based CAD/CAM software.

Book Description
Interest in product data exchange and interfaces in the CAD/CAM area is steadi ly growing. The rapidly increasing graphics applications in engineering and sci ence has led to a great variety of heterogeneous hardware and software products. This has become a major obstacle in the progress of systems integration. To improve this situation CAD/CAM users have called for specification and imple mentation of standardized product data interfaces. These needs resulted in the definition of preliminary standards in this area. Since 1975 activities have been concentrated on developing standards for three major areas: - computer graphics, - sculptured surfaces, and - data exchange for engineering drawings. The Graphical Kernel System (GKS) has been accepted as an international standard for graphics programming in 1984, Y14.26M (IGES) was adopted as an American Standard in 1981 and the VDA Surface Interface (VDAFS) has been accepted by the German National Standardization Institute (DIN NAM 96.4). Although considerable progress has been achieved, the complexity of the subject and the dynamics of the CAD/CAM-development still calls for more generality and compatibility of the interfaces. This has resulted in an inter national discussion on further improvements of the standards. The major goal of this book is to bring together the different views and experiences in industry and university in the area of Product Data Interfaces, thereby contributing to the ongoing work in improving the state of the art.

Book Description
th DEXA 2001, the 12 International Conference on Database and Expert Systems Applications was held on September 3–5, 2001, at the Technical University of Munich, Germany. The rapidly growing spectrum of database applications has led to the establishment of more specialized discussion platforms (DaWaK conference, EC Web conference, and DEXA workshop), which were all held in parallel with the DEXA conference in Munich. In your hands are the results of much effort, beginning with the preparation of the submitted papers. The papers then passed through the reviewing process, and the accepted papers were revised to final versions by their authors and arranged with the conference program. All this culminated in the conference itself. A total of 175 papers were submitted to this conference, and I would like to thank all the authors. They are the real base of the conference. The program committee and the supporting reviewers produced altogether 497 referee reports, on average of 2.84 reports per paper, and selected 93 papers for presentation. Comparing the weight or more precisely the number of papers devoted to particular topics at several recent DEXA conferences, an increase can be recognized in the areas of XMS databases, active databases, and multi and hypermedia efforts. The space devoted to the more classical topics such as information retrieval, distribution and Web aspects, and transaction, indexing and query aspects has remained more or less unchanged. Some decrease is visible for object orientation.
