Yasushi Suzuki,Mohammad Dulal Miahe show that, if the data source is modeled as a single relation, an optimal plan can be found in a time linear in the number of functions in the source but, if the source is modeled as a number of relations that can be joined, finding the optimal plan is NP-hard.

神圣在玷污

Use of Affordances in Geospatial Ontologies,uence of pairs of the form <., .>. A query requests for information necessary to take a decision and the response is the information itself. The set of responses for all decisions identifies DW contents. We show that informational scenarios are merely another sub class of the class of scenarios.

Sustainability, TRIZ and Packagingtexts. Our method is general and it can be adapted to most conceptual modeling languages. We give the complete details of its adaptation to the UML. On the other hand, the method is fully automatic. The method has been implemented. We illustrate the method by means of its application to a case study that refines the Cyc ontology.
