Isn't this the whole point of executable file formats? To avoid loading everything all at once, share immutable segments with other processes, be extremely fast when loading, and integrate with OS page fault handlers to load data on demand?

I don't understand this project at all.

Even if it's possible to query the executable using SQL, we can always just use the SQL frontend to interface with executable data. I mean, ELF as a backend format for the "executable database". Like osquery interfaces with the system using SQL language. Osquery doesn't convert all OS data structures to sqlite :)

Btw, I think SELF is already "coined" by Signed ELF executables - SELF files, existing for example on Playstation 3.
