Engineering applications that use Active DBMSs (ADBMSs) often need to group activities into modes that are shifted during the execution of different tasks. This paper presents a me...
Making a database system active entails developing an expressive event specification language with well-defined semantics, algorithms for the detection of composite events, and an...
