CQL: Categorical Databases | Hacker News

Hacker News discussed CQL, a category-theory-inspired database language, and whether it offers real advantages over SQL.

The post framed CQL as a research language, not a database engine, and compared it with relational theory and standard SQL features.

Commenters debated whether CQL is fundamentally new or mostly a theoretical reworking of familiar relational ideas.

Potential benefits mentioned included stronger compile-time integrity checks, better handling of nulls, and more type-like guarantees.
