TQL Query lets Ana answer questions by querying your ontology directly instead of writing raw SQL against your warehouse. It compiles to warehouse-native SQL under the hood, but every query resolves through the governed metrics, dimensions, and joins defined in your .tql files, so the same question always produces the same answer no matter who asks it. This is Ana’s tool for reading the semantic layer. For the file format itself, including how metrics, dimensions, and relationships are defined and versioned in your ontology repo, see the .tql Manual.
