CQL: Categorical Databases

- Open-source Categorical Query Language (CQL) uses category theory to handle tasks like querying, migrating, and evolving databases.
- CQL includes an automated theorem prover that ensures program correctness and prevents data integrity violations at compile time.
- It preserves data quality with zero degradation, offering perfect provenance by tracking how output rows are derived from inputs.
- CQL enhances developer productivity through higher-level abstractions, such as generalizing SQL's select-from-where to return multiple related tables.
- Key features include flexible I/O (JDBC-SQL, CSV), graphical visualization, rich data integrity constraints, and user-defined functions in Java/JavaScript.
- CQL is stateless, not a database management system, but a functional language for in-memory data processing, scalable like SQL chase engines.
- It is powered by applied category theory and serves as a reference implementation for David Spivak's ologs, with commercialization by Conexus AI.
