A new approach for supporting reactive capability is described in the context of an advanced object-oriented database system called ADOME-II. Besides having a rich set of pre-defined composite event expressions and a well-defined execution model, ADOME-II supports an extensible approach to reactive processing so as to be able to gracefully accommodate dynamic applications' requirements. In this approach, production rules combined with methods are used as a unifying mechanism to process rules, to enable incremental detection of composite events, and to allow new composite event expressions to be introduced into the system declaratively. This allows the definition of new production rules each time an extension of the model takes place. Methods of supporting new composite event expressions are described, and comparisons with other relevant approaches are also conducted. A prototype of ADOME-II has been constructed, which has as its implementation base an ordinary (passive) OODBMS and a production rule base system. © 2002 Elsevier Science Inc. All rights reserved.
