How should data be organized inside a data warehouse?

[Charles Jone]

Appropriate data warehouse data structures are dependent on the use of the data. Typically, a fact table will house a measurable business event, and a dimension table will contain descriptive information like the customer, product or date. A star schema may facilitate reporting, whereas other more normalized schemas may be more appropriate in other operational or complicated situations. The challenge is, make it simple, performant and flexible. I would also note clearly relationships and business definitions. When you are considering the complexity of your warehouse, it’s helpful to look at real world architecture examples, like those of Datalance.
