In the context of data warehousing, what is the significance of degenerate dimensions in a fact table?
- A degenerate dimension is a dimension that is also used as a measure in the fact table
- A degenerate dimension is an alternative term for a primary key
- A degenerate dimension is derived from other dimensions
- A degenerate dimension is irrelevant in data warehousing
In data warehousing, a degenerate dimension is a dimension key that does not have its own dimension table but is instead stored in the fact table. It's essentially a dimension attribute that is treated as a measure due to its significance in analysis. Understanding this is crucial for designing efficient data warehouses.
