Abstract
Todays new applications require that reasonable inferences be made on the data within the database i.e. knowledge of the application domain is required. Knowledge is a higher level abstraction than the data or facts alone. Active databases strive to encapsulate an application domain’s knowledge within the database. REFLEX is an active database research prototype. It’s main tenet is that it provides knowledge management facilities for traditional existing database management systems. This short paper discusses the knowledge management facilities and the unique features that REFLEX provides such as its novel concurrency mechanism, self-activity, its non-destructive knowledge model, and its graphical user-interface.
