We investigatetherole of commutativityin queryprocessing of linear recursion. We give a sufficientconditionfor two linear,function-free,constant-free,andrange-restricted rules to ...
This paper presents a parallel algorithm for recursive query processing and shows how it can be efficiently implemented in a local computer network. The algorithm relies on an int...
: We describe the architecture of a relational databasesystem that is extensible by user-defined data types and operations, including relation operations. The central concept is to...
