Abstract

Presents a rule language with an event based semantics that naturally embeds the behaviour of both active rules and deductive rules and conditional update streams. The language has a quite general data model that allows the definition of both flat and structured data. Language syntax and semantics are formally defined. An interpreter then illustrated. By using several examples, the authors show that this language allows various forms of data manipulations to be expressed as well as quite general triggering computations
