UnverifiedIn text-to-SQL scenarios, schemagate first uses mathematical methods such as BM25, embedding and table-name matching to roughly filter candidate tables, then fuses and ranks them via RRF, and if the user provides an API key it calls an LLM to re-rank the top 20 candidate tables.73% similarUnverifiedSqlDBM provides a semantic modeling layer on top of the physical schema, defining business context, metrics, synonyms, filters, and governed joins.71% similarUnverifiedThe mainstream implementation path for NL2SQL is to feed the database schema as context to a large language model, which infers user intent and generates SQL statements.71% similarUnverified关系型数据库以表-行-列结构组织数据通过SQL查询，非关系型数据库以JSON文档等形式存储数据，牺牲一致性换取Schema灵活性70% similarUnverified当数据库规模较大时需要做Schema裁剪，根据用户问题只检索相关表结构，避免超出模型的上下文窗口限制70% similar
