SQLite is a fantastic piece of work, but I found that once your dataset starts getting large, it becomes quite slow at dumping the data in. Once your sqlite file is over a Gig or so, inserts start slowing to a crawl compared to when the DB is empty (and that is using transactions and dumping in 1000 or 10000 rows at a time). Queries were still surprisingly fast, but inserts really sucked.

It is of course possible that I was missing something, but I think using DBM files would be faster if you need to regenerate the databases often (ie new data files come in regularly)

It does sound like a fun project though...
