hello ,
when we install any package the terminal shows in end " reading database"
(used by package manager like .deb or rpm). but as in linux everything is
nothing but a file. so database shown above must be a part of the filesystem
.. so why we not say that " reading filesystem".
what differs and imposes to say filesystem or database differentlly inspite
of one being one subset of other (filesystem)?

"Database" can be stored as a file or a collection of related
files.  It need not be a hash or RDBM based system.

IMHO,
'reading a filesystem' would imply scanning a bunch of directories which
contain unrelated files, whereas 'reading a database' implies information
is in some sort of defined structure.

Just my $0.02 worth.
