Data mining algorithms use various Trie and bitmap-based representations to optimize the support (i.e., frequency) counting performance. In this paper, we compare the memory requi...
Several requirements for algebra suitable for ecient cost-based optimization are presented. It is shown that known XML algebras do not fully satisfy this requirements. A new alge...
