Another solution (although not particularly platform-independent) is to
store a path name in the database, and have your app open the file
pointed to thusly, read it, and display/ manipulate it however you want.

This is perhaps even more ugly than Chris's solution :)

You could even store just a file offset, and then you might only need one
text file to store all your text. No forget that. You would have too many
problems updating file offsets to make it worthwhile.
