Sorry - maybe i didn't make that clear - Tie::DBI, ties your datastructure to a pre-existing database, i.e. you need to make that database first, then populate from your data. DBM::Deep you can just write and it will do all the creation for you. Once the *populated* database is created, I won't re-create it, for the reasons you pointed out!

As I said I am trying to learn more about databases, so if i am wrong, please correct me!
