The paper treats business meaning as a typed, versioned knowledge graph and moves the query through seven staged phases before any SQL runs: parsing, semantic binding, join-path proof, constraint solving, logical planning, cost-based physical planning, and dialect generation. Useful details for data engineers: bounded BFS with grain and fan-out pruning to prove a join path instead of guessing it, drift detection with KL-divergence, KS statistics and tree edit distance on schema snapshots, and access policy applied as a scope subgraph at compile time rather than masking after execution." + reviewer: + linkedin: "https://www.linkedin.com/in/h-chouhan/" + name: "Harshit Chouhan" + twitter: "https://x.com/chouhanharshit1" + tags: "semantic layer, knowledge graph, query compilation, join path, schema drift, data governance, text-to-SQL, AI agents"
