I think In need a lot of time to understand that ;-).

My mayor Problem is to build a living table-model.
It should contain the formated Data of a Database and the Data
should be updateable through the Table. Also you should can insert
new Data.
The Application schould manage a running competition
(www.windberglauf.de) and there ate some Tables for the
appointments, the results, etc. (Its my first bigger Project and my
first Java Project with a Database)
