Identifying unknown .db file and extracting data?

dwm042 has asked for the wisdom of the Perl Monks concerning the following question:

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.

David.

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)` [download]	[reply] [d/l]

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....)
