Abstract
This chapter presents the NAOS rule system developed at the LSR-IMAG laboratory, University Joseph Fourier-Grenoble. This system incorporates active capabilities into the O2 object-oriented DBMS. It is able to manage and detect various types of events. The detection process is based on a subscription mechanism plus an event graph for composite event detection. NAOS provides immediate and deferred rules. Execution of these rules takes place in nested (recursive) and consecutive (iterative) cycles, respectively. Both kinds of cycles belong to the triggering transaction.
