Data Cube or OLAP approach in Data Mining -

2021-8-1  Data Cube or OLAP approach in Data Mining. Grouping of data in a multidimensional matrix is called data cubes. In Dataware housing, we generally deal with various multidimensional data models as the data will be represented by multiple dimensions and multiple attributes. This multidimensional data is represented in the data cube as the cube ...

Data Cube - an overview ScienceDirect Topics

The resulting cube is a multifeature cube in that it supports complex data mining queries for which multiple dependent aggregates are computed at a variety of granularities. For example, the sum of sales returned in this query is dependent on the set of maximum price tuples for each group. In general, multifeature cubes give users the ...
