Expert Database Systems

xpert database systems are E database management systems endowed with knowledge and expertise to support knowledgebased applications accessing large shared databases. The various architectures, tools, and techniques needed to build such systems draw upon aspects of AI, database management, and logic programming. In fact, the conceptual confluence of these fields creates a synergy promoting new insights and tools for building intelligent information systems. System-resident expertise can improve performance by (I) providing intelligent answers, (2) using database semantic integrity constraints for query optimization, and (3) combining knowledgeand data-driven search techniques in efficient inference schemes. Conversely, expertise may reside outside systems in knowledgebased applications that interpret vast quantities of data and provide users with decision-impelling recommendations. Thus, expert-database R&D seeks tools and techniques that make databases “active” reasoning agents and that allow database systems to support AI applications managing and accessing knowledge/databases. large
