for frontend example see "Source"

frontend = 1 line of code :) ( if you don't count the "check for Koowa" and the templates)

For example with 3 tables checkout com_bib in "source"

The Joomla! example is taken from the hello world tutorial at http://docs.joomla.org/Developers

The Nooku Framework example is written for Nooku Framework v0.7, based on revision 1114.

It's not 100% the same, bit it gives an idea.
