Hi,
I made a few changes in the design, added self join operation plz have a look http://ankitgupt.wordpress.com/2010/05/.
my Git repo's link is http://repo.or.cz/phpmyadmin/ankitg.git although i am having a few issues with the push command,
git push ankitg master gives error To ssh://repo.or.cz/srv/git/phpmyadmin/ankitg.git ! [rejected] master -> master (non-fast forward) error: failed to push some refs to 'ssh:// repo.or.cz/srv/git/phpmyadmin/ankitg.git'
I saw the code of designer and it uses linked table infrastructure, but this infrastructure doesn't exist by default. so for visual builder should this be developed in such a way that it without linked table. or should we follow designer.?
