Case Study I: Chemical Reaction Networksapabilities into the O. 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 nes

Die verschiedenen Automatensysteme,and presents a framework that is used later in the book to characterize the functionality of different active systems. The framework is the major contribution of the chapter, but an important side-effect of its presentation for the book is that much of the terminology associated with active database systems is introduced and defined.

Die Konstruktionselemente des Automaten,is indicated how existing optimization techniques for passive databases can be adapted and extended for use with active rules, and in particular, how the results of rule analysis can be combined with multiple query optimization techniques to support effective optimization of rule bases.

Die Konstruktionselemente des Automaten,ms in most commercial database systems is no guarantee that they will be used. This is partly due to the lack of sophisticated tools to assist in the process of designing, debugging, and administrating large rule sets. This chapter reports advances achieved so far, and identifies areas where enhancements are required.

Entscheidungsverfahren für ,-Automatenave been developed independently by different vendors, and triggers developed for one system generally do not work with another. This chapter describes how triggers are supported in the SQL3 standard, and in particular how the triggers relate to other features of the standard.

Entscheidungsverfahren für ,-Automateny of Zurich, the main goal of which is the development of an active object-oriented database system supporting advanced active functionality. The first implementation of the SAMOS prototype (release SAMOS 1.0) was completed in 1995 and is available in the public domain (http://www. ifi.unizh.ch/DBTG/SAMOS/release.html).
