A multi-dimensional architecture is a data cube. The data cube is an abstract of data for displaying aggregated data from a variety of viewpoints. As the 'measure' attribute, the dimensions are aggregated, as the remaining dimensions are known as the 'function' attributes. In a multidimensional...
C. Data Cube Aggregation Data cube aggregation is a data mining technique that involves summarizing and aggregating data along multiple dimensions to create a concise and informative data representation. It is commonly used inonline analytical processing (OLAP)and data warehousing applications to provide ...
This paper work is aimed to give a comprehensive view about the links between computation regarding data hierarchy through data cubes and data mining. The paper discusses the possibilities of hierarchical data computation, data mining and knowledge discovery. In this paper data mining algorithms are ...
