Many application domains involve constraints that, at a conceptual modeling level, apply to one or more schema paths, each of which involves one or more conceptual joins (where the same conceptual object plays roles in two relationships). Popular information modeling approaches typically provide only weak support for such join constraints. This paper contrasts how join constraints are catered f...

An intention of MapReduce Sets for Reduce side join part file expressions analysis has to suggest criteria how Reduce side join part file expressions in Reduce side join part file data can be defined in a meaningful way and how they should be compared. Similitude based MapReduce Sets for Reduce side join part file Expression Analysis and MapReduce Sets for Assignment is expected to adhere to fu...
