Data

relationalai.semantics.frontend.base

Data(
    df: DataFrame,
    model: Model,
    schema: dict[str, Concept] | None = None,
    register_columns: bool = True,
)

Represents a temporary table backed by in-memory data.

Data objects are created by Model.data (and the convenience function data). They behave like a Table, so you can refer to their columns (for example d.name or d["name"]) in queries.

Notes

Most users should not instantiate this class directly. Prefer Model.data.
