Technology of Exploratory OLAP Based on the Integral Analytical Model

The paper presents the original approach to the exploratory OLAP of the heterogeneous resources based on the integral analytical model. Applying the multidimensional data model as a technological fundament allows to analyze the structure of the joining sources according to unified notation, allows to present information in form of native multidimensional view and provides efficient integration of the sources by matching the dimensions. Storing information about the physical location and comparability of the analytical concepts within multidimensional model enables to form automatically the exploratory queries. The proposed approach leans on analysis and matching resources on the conceptual level (i.e. without physical data consolidation) that allow to process data with a lot of records and entities. In the paper, the requirements to exploratory OLAP technology are defined and the main issues and their solutions are formulated based on preliminary scientific results. The principal stages for analytical exploration support according to author’s method of the integral OLAP-modeling are described.
