The uptake of parallel DBMSs is being hampered by uncertainty about the impact on performance of porting database applications from sequential to parallel systems. The development of tools which aid the system manager or machine vendor could help to reduce this problem. This paper describes an analy
## Abstract We will prove in ZermeloβFraenkel set theory __without axiom of choice__ that the transitive hull __R__\* of a relation __R__ is not much βbiggerβ than __R__ itself. As a measure for the size of a relation we introduce the notion of ΞΊ^+^β__narrowness__ using __surjective__ Hartogs numbe
