How many dimensions in an OLAP cube?
For a typical measure there are 3 to 8 dimensions. In a simple case, you may have Market, Product, Time. Telling where it was sold, what was sold, when it was sold. Or, you could have Geography, Channel, Customer, Product, Time In financial applications, you may have a few measure dimensions to select the data you want: scenario, version, account and then add a time dimension, an entity dimension The issue of dimensionality is discussed in detail in The Multidimensional Data Modeling Toolkit, you may want to take a look at that.
A cube has 12 edges. An easy way to figure out how many edges is to multiply the number of edges of the original shape, a square(4)and multiply it by how many dimensions it has(3). To figure how many dimensions remember that to figure volume of a cube you multiply length X width X height, 3 dimensions.
This question cannot be answered sensibly. A centimetre cube is a measure of volume, with dimensions [L3]. A gram is a measure of mass, with dimensions [M]. Basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information. It takes only a little mental effort to compare a centimetre cube of air and a cm cube foot of lead to see that the two will have very…
In SQL Server Analysis Services, a cube is a structure for representing data across multiple dimensions. For example, an Sales cube might have Product, Price and Customer dimensions, and each Sale would be measured against each of these dimensions. In SQL Server's T-SQL language, "cube" is an option that can be applied to the GROUP BY clause.
