[exim] pre - information - virtusertable - aliases (exim)

hello

sorry for the question i realy try (the last days and now) to read much as
possible, i just want to ask now if i understand it correctly.

Until now i worked with sendmail , which has too virtusertable like
me@??? localboxname

When i understand correctly the Exim Docs, its the same way under exim with
virtualdomains, but the file runs als "alias" file is that correct?

Eg. under sendmail
/etc/mail/aliases (alias file)
/etc/mail/virtusertable.db (DBM table file)

Is under exim, alias and virtusertable files for same use?
my config would be

virtuals:
driver = redirect
domains = dbm;/etc/domains.db
data = $(lookup{$local_part}dbm{/etc/$domain.aliases}}
no_more

in aliases then
me@??? localboxname

friendly regards
