How is a table with only primary key stored on disk?
It says "An interior page contains K keys together with K+1 pointers to child b-tree pages."

How to make sure the K keys fit in a page? Can keys be strings so that there will be no guarantee that K keys will fit in a page?

Also what are the keys metioned in fileformat.html and the keys in the sense of SQL language? Thanks.
