The paper is dealing with data cubes built for data warehouse for OLAP purposes. OLAP (Online Analytical Processing) system offers multidimensional data analysis in which large volume of historically collected data is computed. To decrease the query time and to provide various options to the ...
When data is stored in a data warehouse, BI tools can perform complex aggregations across multidimensional datasets, typically using the Online Analytical Processing (OLAP) standard. They can display data in multi-dimensional views, using the concept of OLAP cubes. How to Implement an Enterprise Da...
