Concurrent rule execution in active databases
Cataloged from PDF version of article.An active DBMS is expected to support concurrent as well as sequential rule execution
in an efficient manner. Nested transaction model is a suitable tool to implement rule execution as it can
handle nested rule firing and concurrent rule execution well. In this paper, we describe a concurrent
rule execution model based on parallel nested transactions. We discuss implementation details of how
the flat transaction model of OpenOODB has been extended by using Solaris threads in order to
