I've become rediculously adept at creating text-based databases; that is, databases stored in plain text files delimited by a particular character. In some instances I use up to as many as three seperate text files to store all of the data and individual records are sometimes so long that Notepad can't even display it on one line and automatically wraps two or three times. But it all works great.
What drawbacks or problems might I run into by doing this? I know it's not at all efficient, but this is on an Intranet server serving a small number of people so that's not a concern. Anything else I should be wary of?
