Database management is attracting wide interest in both academic and industrial contexts. New application areas such as CAD/CAM, geographic information systems, and multimedia are emerging. The needs of these application areas are far more complex than those of conventional business applications. The purpose of this book is to bring together a set of current research issues that addresses a broad spectrum of topics related to database systems and applications. The book is divided into four parts: - object-oriented databases, - temporal/historical database systems, - query processing in database systems, - heterogeneity, interoperability, open system architectures, multimedia database systems. COMPOSE: A system for composite specification and detection.- Access controls in object-oriented database systems - Some approaches and issues.- The decomposition property of non-deterministic databases.- The architecture of an object base environment for simulation.- Transition from a relation to object model implementation.- An object-oriented knowledge model for KBMS-supported evolutionary prototyping of software systems.- Applying OOAD in the design and implementation of an intelligent geographic information system.- Indexical databases.- A temporal query language for a conceptual model.- A data model for time-series analysis.- A relational model and SQL-like query language for spatial databases.- Parallel query processing.- Towards flexible distributed information retrieval.- Efficient parallel recovery in replicated databases.- Document allocation in multiprocessor information retrieval systems.- Amalgame: A tool for creating interoperating persistent, heterogeneous components.- Correctness and enforcement of multidatabase interdependencies.- FEMUS: A federated multilingual database system.- Communication and synchronization issues in distributed multimedia database systems.- Multimedia database systems.
