In this report, you will learn how to use the "disjunction" method. This is one of the most important methods that return the disjunction of two expressions. In addition to basic operations (child, descendant, filter, and template), we are. Consider disjunction, DTD and variable variables WRT study two semantics: (1) variables defined by external conditions, (2) the values of variables defined existentially Fits almost complete classification of complexity. The problem of deterrence WRT these fragments. (Wiley, 2004, 12) Current unnesting methods fail in the presence of disjunctive predicates. Despite the fact that the ...
