The key operations in All of the previous chapters focus on the left-hand side, the transformation process from the operational database to the data warehouse, where we discuss in length the step-by-step transformation process of various cases, using extensive case studies OLAP (On-Line Analytical Processing) [9, 5,, 2,] is an important notion in data analysis. It is a technology that enables analysts to extract and view business data from different points of view. There exists a sim-ilar need to deploy graph analysis from different perspec-tives and with multiple granularities Carlos Hurtado. OLAP systems support data analysis through a multidimensional data model, according to which data facts are viewed as points in a space of application-related “dimensions”, organized into levels which conform to a hierarchy On-Line Analytical Processing. Given the un-derlying data, a cube can be constructed to provide a multi-dimensionaland multi-levelview, which allows for effective analysis of the data from different perspectives and with multiple granularities.
