草稿数据和正式数据的英文命名应该怎么取比较精确？

Draft data and formal data are both accurate names for these types of data. However, if you want to be more specific, you can use terms like "preliminary data" or "working data" for draft data, and "final data" or "official data" for formal data. Other possible names for formal data may depend on the specific context, such as "validated data" or "certified data" if the data has gone through a verification process.
