I think, when the season is over, the table will be closed to change its contents, so the history data for this season will be written to the data tables of the clubs or users. You gave me a lot of input about databases and how to put them together. I removed the double time/data stuff from the seasons tables and it works fine I made a speed-test and it is a bit faster now. Now there are some features missing, I will put into, a checkbox 'only today' shows you only the games played today. In combination with a checkbox 'games without result' gives the visitor an easy way to find out if a result wasn't reported yet - interesting for coaches, league managers and players, too. > <snip> > Have you considered defining "views" and "triggers" -- based upon > the user privileges you run queries using views that only expose the > permitted data (and use triggers to permit properly updating the > underlying tables when edited). I will do the user managment based on the tables in the user/club/federation tables I am actually thinking about - views are an interesting feature. This is very complex, the user table will be the beginning to start from, where the personal data is stored. userID, name, gender, date of birth, club and e-mail as must haves. Based on this there is a role table, where the roles for all persons for an area in the system will be placed.

Hopefully my python code will handle that for me :-) I really like SQLite, very easy to use and to backup. The idea behind the user managment is, that the users manage themselves, I will only step in when something does not work as it should... -- http://mail.python.org/mailman/listinfo/python-list
