Research on Multimedia, Medical and Web Information Systems
Description
Information systems technology with emphasis on the management (processing, information extraction, dissemination and retrieval) of complex information. As such, a database is not only considered from a standalone perspective; its strength lies in its potential association with other technological approaches e.g., web, content-based approaches.
