I have a question on Data warehousing - Dimension Types. I am interested to know what are different types of Dimesnions that can be used in Data warehousing.I am aware of three different types of Dimensions -
1. Confirmed Dimension
2. Junk Dimension
3. Degenerated Dimension
Is this list correct or are there any more types? Please advice.
Depending on the author you may get anything in between nine to a dozen "types" of dimensions - not to mention sub-types like Slowly Changing Dimensions of the Type 0, 1, 2 and 3.
