This volume contains 14 survey articles by reputed database researchers. They give an account of the state of the art, present research highlights and offer an outlook into the '90s regarding the most likely evolution of database technology-research, ad-tech, products and applications. The volume is structured into the following parts: - The evolution of database technology and its impact on enterprise information systems (keynote paper); - Demands on database systems in the '90s (office, engineering, science, multimedia, standardization); - User aspects (application programmers, ad hoc query users); - Database system and architecture concepts for novel applications (data models, object orientation, deductive DBMS, extensibility, data replication); - System and implementation aspects (performance and reliability, distributed and cooperative DBMS, hardware impact). The volume may serve as an orientation for all those who are interested in database systems and their impact on computer applications.
