Identifying unknown .db file and extracting data?

[dwm042]

I have an unknown .db file and I've been asked to extract data from it. It's probably a Berkeley db file but I can't be certain of that. Any way to see if it is a Berkeley file, and if so, extract the data from it? A Perl based solution has some preference, though I'd hardly turn down a solution in a compiled language.

Treat it as if it were a Berkeley db file (see BerkeleyDB), and if it works, fine, otherwise try the next likely db format...

Also, the file utility often helps:

$ file mydata.dbm
mydata.dbm: Berkeley DB (Hash, version 9, native byte-order)

As would db_stat or db_verify

Speaking as someone who sells a software product that is designed to repair “.DB files,” I think there must be hundreds of different file formats out there (on Windows) that use that file extension.   Grrrr....   (Sigh....)
