Abstract: Optimization of nested queries, in particular finding equivalent “flattened” queries for queries that employ the SQL sub-query construct, has been researched extensiv...
Abstract. We present an algorithm for asymptotically efficient multiway blockwise in-place merging. Given an array A containing sorted subsequences A1, . . . , Ak of respective le...
Most operations of the relational algebra or SQL - like projection with duplicate elimination, join, ordering, group by and aggregations - are efficiently processed using a sorted...
We present two beneficial rendering extensions to the Projected Tetrahedra (PT) algorithm by Shirley and Tuchman. These extensions are compatible with any cell sorting technique,...
Abstract. The fact that so many different kinds of coordination models and languages have been proposed suggests that no one single approach will be the best for all coordination p...
