Title: Performing OLAP Operations in Data cube with Dimensions Having Irregular Hierarchical Relationships
Keywords: OLAP, Data cube, Summarizability, Hierarchy transformation, OLAP operations

Abstract: OLAP provides for analysis of large collections of historical factual data aggregated by the levels of hierarchically structured dimensions. In case that a hierarchy is irregular aggregation results will be incorrect. Algorithms for rendering irregular hierarchies summarizable thus ensuring correctness of aggregations are proposed. Mechanism for performing basic OLAP operations in relational environment is designed.
