Adding dimensions to the FirstCube project
A dimension
in Analysis Services is a group of characteristics that describes a fact row. Previously, when working with the FirstCube
project in this book, you have worked with dimensions such as date and product. These have all been dimensions with a direct relationship to the fact table. However, several other types of dimensions can be used in Analysis Services. In this chapter, we will add dimensions of different kinds to the cube.
Adding referenced dimensions

column in the FactResellerSales
table, instead, this column exists in the DimReseller
table. Analysis Services solves this using something called a referenced dimension. To create a referenced dimension, perform the following steps:
