Short answer

How can I check dataset schemas using my AI?

Your agent uses the connector to pull metadata for specific tables. This reveals column names and data types so you can verify the structure before running queries. You get a clear map of the dataset to prevent errors.

The outcomes

What you get from schema inspection

The AI maps out the data landscape so your queries actually work.

STRUCTURE

Table architecture

The agent identifies how tables are organized. You'll see the hierarchy of the dataset without manual digging.

TYPES

Column data types

Your agent checks if a column is a string, integer, or float. This prevents type mismatch errors in your analysis.

VALIDATION

Schema verification

The AI confirms the exact column names available. You won't waste time guessing which headers to use in your code.

HUMAN

Manual review

You decide if the schema matches your research needs. The AI provides the map, but you make the final call on the data's relevance.

The workflow

What your AI does when the request arrives.

The agent moves from broad discovery to specific column validation.
