MongoDB Like PICK in the 1906's

Hi, I’m new to Mongodb, I’m following the courses, which I think are very good.
Many years ago I worked with a system called “PICK” or “UNIVERSE”, created in the 1960s.
Saving distance is really similar in many concepts, such as for example the embedding of objects, “attribute patterns” and in geneal the handling of data. It’s the same idea, the same philosophy.
I feel like a fish in the water.
