Riassunto
This book constitutes the refereed proceedings of the 7th International Conference on Database and Expert Systems Applications, DEXA '96, held in Zurich, Switzerland, in September 1996.
The 77 revised full papers included were selected from a total of nearly 200 submissions. They report on a broad spectrum of advanced applications and the design of database and expert systems. Among the topics addressed are object-oriented databases, active databases, temporal databases, transactions and concurrency, relational databases, CSCW and workflow systems, parallel and distributed systems, expert systems, knowledge-based systems, and information retrieval.
