DATASCOPE OVERVIEW 2.1 Architecture As depicted in Fig. 1, the DataScope system consists of threemaincomponents: Webinterface,user-interactionserver, and query engine. The user-interaction server translates user-interface events and parameters into query statements recognizable by the query engine. The … WebExperience tells us that although data analy-sis tasks may involve a high dimensional space, most OLAP operations are performed only on a small number of dimensions at a time. Based on this observation, we propose a novel method that computes a thin layer of the data cube together with associated value-list indices.
