....happen that rule execution ran into a cycle. Therefore, termination analysis became an issue that had to be treated in the context of usability. We have addressed these questions in SAMOS as follows: Performance issues of active object oriented DBMS: We have developed the Beast benchmark [41, 46] which helped evaluating the performance of SAMOS and other ADBMS. Usefulness: We evaluated SAMOS in various application scenarios, such as banking, consistency constraints, and workflow management. Tools to support users during the implementation of ADBMS applications: The SAMOS tools [69, ....
....It concentrates on the active functionality; for analyzing only passive functionality, 007 itself can be used. Beast has been used extensively to measure (and improve ) the performance of SAMOS [41] A comparison with the performance of other ADBMS has also been pursued; results are reported in [46]. The tests proposed by Beast are subdivided into three classes: event detection tests, rule management tests, and . rule execution tests. 2. BEnchmark for Active database SysTems 19 of 31 Event detection tests measure the performance of primitive and composite event detection. In ....

....the event was generated T, where as the latter refers to the time when the event was detected by the system, which can be a time point T n. For example, an event manager is most likely to spend a non trivial amount 1. Active Real Time Database Systems 7 of time when detecting a composite event [GBLR96] Depending on whether the deadline is relative to the time of event occurrence or event detection and the importance of the triggered transactions has a dramatic impact on the requirements of the real time system. If the deadline is relative to the event occurrence, time cognizant mechanisms ....
....deferred. 4.5 Condition Evaluation Rule conditions in active databases are implemented as either boolean expressions, methods or database queries. Sophisticated implementations of active databases can apply techniques proposed for query optimization in order to speed up the condition evaluation [GBLR96] 4.6 ARTDB Prototypes and Platforms We will elaborate here on active real time database systems that have been built or that are currently under development. We will highlight the specific research problems that have been are under investigation in each one of the following projects: HiPAC, ....
