In this paper, we present an approach that allows evaluating an XPath query in arbitrary directions, including a mixture of bottom-up and top-down direction. For each location step, it can be decided whether to evaluate it top-down or bottom-up, such that we can start

Cellular Automata: Research Towards Industryblem is formalized as follows: given a set of queries and a budget e.g., an available memory space, find the objects to materialize (views and/or indexes) that (1) satisfy the given budget and (2) minimize the query cost. In this paper, we depart from this setting by adopting a user-centric point of
