Computer Aided Database Design

Computer-aided Database Design

Hardbound. The book describes current research and development activities carried on by the DATAID research project in the area of methodology and tools for database design.The present book is divided into two parts. The first part is devoted to the description of tools that have been developed in order to support the conceptual, logical and physical design of a database application. The second part is devoted to a review of the DATAID-1 manual methodology, together with reports of its experimentations and with proposals of extensions as regards distributed design and dynamics handling.Main Features of this book are: 1. Indications of the basic characteristics for a tool which supports the design activities and handles the related documentation. 2. Considerations about the role of tools with respect to methodologies. 3. Description of several advanced tools developed for the various design phases. 4. Considerations about the role of methodologies in t

CAD*I Database

In this ESPRIT research report of a group of engineers in the CAD*I project the possibility of using a database management system (DBMS) for computer aided design (CAD) purposes is analyzed and conditions are derived that enable CAD systems to manage CAD models containing increasing amounts of data and more and more intelligent relations. Today CAD models constitute isolated islands of data stored in independent files, and to create and maintain relations between pieces of information stored in several models (files) in a multi-user environment is a complex task. At a conceptual level, a relational DBMS associated with the language SQL (ISO standard) is the ideal tool to create and maintain such relations. At the implementation level, it is of the highest importance to define the optimum granularity of information to be stored in the database in order to get a good response time from such a system.
