Abstract : This volume presents practical ideas and prototype systems for integrating existing information and communications resources. It is divided into four parts. The first part, 'Knowledge-Based Pictorial Information Systems,' describes a prototype system that enables users to manage all types of information, especially pictorial information. The Image Database Management System (IDBM) provides an integrated standard that can be used to specify the information to be retrieved, in a format acceptable to all participating computers. The second part, 'Storage and Retrieval of Pictorial Information in Heterogeneous Computing Systems,' studies existing techniques for storing pictorial images, such as bit-mapped mechanisms, vector-based techniques, and quadtree and pyramid-oriented approaches. Recent advances in compression techniques are also discussed. The third part, 'An Expert System for Accessing and Integrating Design Analysis Knowledge,' presents an approach for integrating information from multiple design environments. Mechanical design packages such as CADAM and CATIA, thermal design packages such as ITAM and PHOENIS, and other specialized packages can be linked together through a common expert system. The fourth part highlights a number of critical connectivity issues in the context of data communication networks maintained by two large organizations. (RH)
