Calibre has 2 main parts per book:
1) the DB entry (actually many pieces: as it is a relational DB)
2) The books format(s) just stored in the file system
The DB entry contains a PATH to the book as well as lots of metadata.

Ownedbycats is referring to the command line tools, that can be used to perform tasks.(see the online help) No need to know SQL as all the tools do the needed lifting (without risking library integrity).
