I am stuck when it comes to plan my application.
The purpose is to importdata from a database and export it to a cvs file. During the transfer should some data be validated (email adress). How shuld one build such a thing in good OO-structure.
I have writen a main class wich have communciate with a dbConn class, importClass, exportClass. The data is sent all over by Hashtable and strings, this does't feel like good OO.
Plase give me a hint in the right direction.
