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...
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 ...
For data elimination, methods for data transformation may also be used. If we build a new function that blends the features to make the process of data mining more effective, it is called a choice of attributes.For example, male/female and student traits may be built into male/female ...
We also introduce a cube cell notation that is useful for describing data cube computation methods. 5.1.1 Cube Materialization: Full Cube, Iceberg Cube, Closed Cube, and Cube Shell Figure 5.1 shows a 3-D data cube for the dimensions A, B, and C, and an aggregate measure, M. Commonly ...

Multidimensional cube space analytics rely on the high-dimensional structure of the data to explore multi-lattice and abstraction levels of the cube. Common dimensional exploration methods rely on bottom-up, top-down approaches, namely rollup, where fine granularities are gradually aggregated in coarse...
