Data mining cube

What is OLAP (online analytical processing)? - Definition ...

The result is the "measure"; each OLAP cube has at least one to perhaps hundreds of measures, which are derived from information stored in fact tables in the data warehouse. OLAP begins with data accumulated from multiple sources and stored in a data warehouse. The data is then cleansed and stored in OLAP cubes, which users run queries against.

When to use a cube to do data mining? SSAS - Cross Validated

You do not need to have a cube or an OLAP database to do data mining. Unless your data is already stored in a cube, or you want to mine OLAP dimensions or the results of OLAP aggregations or calculations, we recommend that you use a relational table or data source for data mining. When would I want to mine OLAP dimensions instead of views?

Data mining cube with value facts

 · If the only zero value in your data correspond to null (missing) value, you can either filter those out from the input data or have another computed measure be null whenever the measure is 0 and use that measure as input to the data mining algorithm. Hope this helps

Iceberg-Cubes - Department of Computer Science

An Iceberg-Cube contains only those cells of the data cube that meet an aggregate condition. It is called an Iceberg-Cube because it contains only some of the cells of the full cube, like the tip of an iceberg. The aggregate condition could be, for example, minimum support or a lower bound on average, min or max.
