問題文
A weekly revenue figure changed after an upstream correction. The analyst needs to show stakeholders both the number as it was reported last Friday and the number as it stands now. Which approach produces that comparison?
選択肢
- Recreate last Friday's number by subtracting the correction amount from the current figure, using the note the upstream team sent.
- Compare the current figure against the value stored in last Friday's screenshot of the dashboard, since that is the reported number.
- Look at the table's history to read the revenue value directly out of the commit log entry for last Friday.
- Run the same aggregation twice, once against the table as of last Friday using time travel, and once against the current table.
