Abstract
Active OODBMSs must provide efficient support for event detection, composition, and rule execution. Previous experience, reported here, building active capabilities on top of existing closed OODBMSs has proven to be ineffective. We propose instead an active OODBMS architecture where event detection and rule support are tightly integrated with the rest of the core OODBMS functionality. After presenting an analysis of the requirements of active OODBMSs, we discuss event set, rule execution modes, and lifespan of events supported in our architecture. We also discuss the coupling of event composition relative to transaction boundaries. Since building an active OODBMS ex nihilo is extremely expensive, we are building the REACH active OODBMS by extending Texas Instrument 's Open OODB Toolkit. Open OODB is particularly well suited for our purposes because it is the first DBMS whose architecture closely resembles the active database paradigm. It provides low-level event detection and invokes a...
