HI!
I also think a database is a better approach than a file base system. But
you didn't address the first and biggest think to do. Before you can start
coding you should really plan your database.
To create a database it is a real big work. You need to plan in advance
even for feature are not at the horizon yet. If you plan it correctly you
can then include localization as well.
I was thinking to jump on KStar to help, so maybe this is my cue. I will
have to learn how the data are structured and I can help with the database
development. But I would like to see some diagram here in the Kde-Edu list.
So that all the KStar team can also have a look and give their opinion.
Cheers
Marco
