There are many different types of data models that can be utilized in the data warehousing arena. I would like to clarify the types of models that are useful for designing and deploying dimensional structures. This column is not intended to be a discussion about or in any way to compare and contrast the uses of entity-relationship modeling and dimensional modeling. Perhaps I'll discuss that at another time.

This column includes references to detailed dimensional design topics. It is intended to provide a context for the entire modeling effort. Some of you may not be familiar with all of the design topics mentioned this month. I plan to address these topics in the future.
