Play with RooQL

Play with RooQL is a browser-based playground that compiles natural language questions into SQL from an Apache Ossie model.

Play with RooQL is an interactive browser playground designed to demonstrate metric compilation and query execution. Users select predefined questions about a sample coffee shop to see how the tool translates metrics into SQL. The system uses an Apache Ossie model for metric definitions and executes the generated queries locally using DuckDB. Nothing is sent to a server during this process, ensuring local execution. It targets developers and analysts interested in semantic modeling and text-to-SQL compilation.
