問題文
A utility ingested meter readings in three separate feeds with inconsistent units and trailing whitespace in the account column. The team wants one clean feed before mapping. Which capability is designed for that work?
選択肢
- An identity resolution ruleset, since normalizing values across several sources is exactly what match criteria do when they compare the same attribute from different feeds during a run.
- A data transform, which combines, shapes, cleans, and prepares the ingested data inside the platform before it is modeled.
- A formula field on the target object.
- A definition written in query language can express the same cleansing logic and its result is stored as an object, so a calculated insight is the right mechanism.
