a flexible XML query benchmark

Irena Holubová, Maroš Vranec


FlexBench represents a new, flexible approach to XML benchmarking. The flexibility is given by two aspects. Firstly, FlexBench involves a large set of testing data characteristics so that a user can precisely describe the application. And, secondly, FlexBench is able to adapt the set of testing queries to the particular set of synthesized testing data. Hence, contrary to the existing works, the testing is not limited by the fixed set of queries and basic data characteristics (usually only size) to a single (and often simple) application.

Where to get it

FlexBench is open-source and is therefore freely accessible. Users are welcome with their feedback.
