問題文
An author wants contextual insights on a visualization that draws on a dataset holding several joined tables. What does the documentation require of that dataset?
選択肢
- The option that preserves grain has to be set on the fact table, which declares which of the joined tables acts as the fact table.
- The joined tables have to be split into one dataset each, since a dataset with more than one table falls outside what the feature supports.
- The option that preserves grain has to be set on every dimension table, which declares that none of them acts as the fact table.
- The related columns have to be trimmed to fewer than six, since a dataset with more than one table raises the count of columns that get compared.
