The koryki transpiler: turns KQL and IQL -- concise, human-readable query languages written against a semantic layer rather than against tables -- into SQL, with grammar, intermediate query model, rewrite rules, type checking, a function catalog and a JDBC execution layer. Pair it with the artifact for the target database: koryki-duckdb, -postgresql, -oracle, -snowflake, -trino, -mariadb, -mssql or -sqlite.
