Today's information systems utilize a variety of sophisticated software tools and systems. Database systems form the core technology supporting modern information systems. Previous work in this area has focused on semantic data models, knowledge-based systems, transaction management, GUI query tools, and state-of-the-art database systems (object-oriented, distributed and federated). Ongoing efforts include work in interoperable information systems (with emphasis on transactional workflow management), global information systems (with emphasis on infrastructure for managing heterogeneous data, meta-data for digital media, and information brokering), and intelligent information systems (with emphasis on integrating knowledge, data and models).
