[delegate]

Not really. This db allows traversing the (deeply nested) data structures without loading them into memory. Eg. In Clojure you can do ``` (get-in db [:people "john" :address :city]) ```

Where `:people` is a key in a huge (larger than memory) map. This database will only touch the referenced nodes when traversing, without loading the whole thing into memory.

So the 'query language' is actually your programming language. To the programmer this database looks like an in-memory data structure, when in fact it's efficiently reading data from the disk. Plus immutability of course (meaning you can go back in history).
