Issues in Active Databases

چکیده
This paper examines an emerging technology known as active databases. The focus is on issues which need to be considered in their development and the way they have been addressed in currently implemented systems. We examine what deenes active behavior, why it is useful, the semantics of its spec-iication and choices that have to be made when realising it in an actual system. We see that a multitude of options exist when designing an active database and future research will prove to be both necessary and fruitful.

These systems impose certain unique requirements on databases that monitor and control them. These requirements are such that traditional data and transaction management models appear inadequate. We present an analysis ...
