問題文
The hospital group must decide the default table type for their new clinical data platform. They want maintenance automated and later want external research tools to read the data under governance. Which choice and follow-on decision fit?
選択肢
- External tables as the default, so research tools can read the files directly from storage.
- Foreign tables as the default, so the clinical systems remain the source of truth.
- Unity Catalog managed tables as the default, with external access provided through the open APIs and credential vending rather than direct file access.
- Managed tables as the default, with research tools given the storage path so no additional setup is needed.
