He is a human database

There's
Sie ist ein wandelndes Lexikon.
Sometimes also used in this form
Sie ist ein lebendes Lexikon.
I think both Alleskönner and Tausendsassa could fit as well, if a more colloquial term is needed. Multitalent would be another option.
The word I would use is "savant." It was originally French, may have been adopted in German, but I'm not sure.
