I've thought about building a better query language too. I'd love the ability to model sum types in databases, something like:

    enum SchoolType {
       College {
           degrees: Vec<Degree>
       },
       HighSchool
    }

It's such a common pattern and yet it's so annoying to model in a normal relational database. I wouldn't be surprised if the rise of NoSQL is tied to the inability of relational databases to model basic patterns like this.

Part of me has wondered if a language is the solution. Maybe just a better query builder with support for sum types is necessary. But I suppose there's something useful about having a consistent model based around a language, even if people aren't writing the language directly.
