Semantic layer & auto-mapping
To evaluate auto‑mapping, test on representative schemas and review the generated entities, joins and metrics.
Criteria include accuracy (correct joins and data types), completeness (coverage of all relevant tables), and ease of editing.
Also assess performance: does the generated model run efficient queries?
Look for features like entity detection, sample data preview, and suggestions based on data patterns.
Consider how the tool handles edge cases like many‑to‑many relationships or slowly changing dimensions.
MageMetrics provides a preview interface and allows users to refine the auto‑generated semantic graph, while learning from corrections to improve future mappings.
