Column databases store data in a column-wise format instead of row-wise, which allows for better compression and thus a reduction in storage space. However, this trade-off requires more computing time to access the data. The other options listed are all techniques for organizing data in a data warehouse and are not directly related to storage space savings or computing time trade-offs.
