yes, i think it will make sense to katgirl. katgirl has a 'site' and currently stores data in a flat-file. that implies at least a bit of knowledge about CGI, reading/writing files, and storage of persistant data. definately above the threshold for understanding that a magical 'tie' can link a HASH to a file automatically.
not only that, but there wasn't another response that actually answered the OP question as to what those DBM modules that are already installed actually do. database class this, read these books, plan requirements, ... made everything sound so hard.
though i will admit to answering the question because katgirl is of the feline persuasion.
