Are you asking about HF freqs (below 30 mhz) or above this range? Not very specific here...
If you're asking about HF, go see the latest MT which has an intro article to the subject...there's no db for something that covers so large a range...
However, if you are talking about 30 mhz and up, then this is the wrong place for this question - however....
No such animal as a milair 'database' per se, although our database here has
some information (for example the milair freqs for the
ZBW ARTCC - and a note here, ignore the FAA listings - they're frequently out of date). Same kind of deal about company freqs - there's no one database I know of that lists all the company freqs (although you could search the FCC database, I think...that is, if you were a premium subscriber...) although we have at least some of the freqs that
Logan uses
Your best bet in both cases is the Scan New England wiki

[edit] I forgot to mention that SNE has a dedicated milair forum as well as one for civil aviation.
