In this tutorial, we will learn about the data cube technology in data mining, what is data cube technology used for, data cubes classifications. By Palkesh Jain Last updated : April 17, 2023 What is Data Cube
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 ...
It is important to note that the data you use for data mining does not need to be stored in an Online Analytical Processing (OLAP) cube, or even in a relational database, although you can use both of these as data sources. You can conduct data mining using any source of data that ha...
Sections 5.2.2 and 5.2.3 discuss methods for efficient iceberg cube computation. Introducing iceberg cubes will lessen the burden of computing trivial aggregate cells in a data cube. However, we could still end up with a large number of uninteresting cells to compute. For example, suppose that...

In a reasonable time frame, data aggregation will allow analysts to view and analyze vast volumes of data. Hundreds, thousands, or even more atomic data records may be represented by a row of aggregate data. Instead of having all of the computation cycles to access each underlying atomic data...

Suh and Chung [44] present a distributed algorithm for data cube computation that can be adopted in shared-nothing systems. The proposed algorithm gains efficiency by adopting the workload assignment strategy that reduces the total network cost and allocates the workload evenly to each processor, ...
A data warehouse is modeled for a multidimensional data structure called data cube. Each cell in a data cube stores the value of some aggregate measures. Data mining in multidimensional space carried out in OLAP style (Online Analytical Processing) where it allows exploration of multiple combinations...
