Pre-selecting data to fit management's decisions, like in option A, seems risky. I recall a practice question where bias in data selection led to poor outcomes.

I'm a little confused by this question. The options seem to be focused on different aspects of the data, but I'm not sure which one is the "BEST" approach. I might need to review my notes on data warehousing to make sure I understand the key principles here.

Option D definitely stands out to me as the best choice. Standardizing and cleansing the data before loading it into the data warehouse is crucial to maintaining data quality and integrity. The other options seem to be more about manipulating the data, which could compromise its accuracy.
