mnemiq vs orionbelt-semantic-layer

mnemiq: mnemiq is an open-source Text-to-SQL engine designed to answer natural-language questions over databases, emphasizing tunability and transparency. It ensures verifiable results by separating SQL generation from execution, providing clear reasons for query refusals rather than generating incorrect answers.; orionbelt-semantic-layer: OrionBelt Semantic Layer is an open-source Semantic Sidecar that injects governed business semantics into AI and analytics systems without architectural changes. It allows users to define dimensions, measures, and business rules in YAML, which are then compiled into optimized, dialect-specific SQL for various databases.
