Tutorials and talks on the same subjects are also good for another reason:
Tutorials focus on the actual techniques and how to use the features, while
talks can more easily focus on high-level strategy regarding solving a
problem. For me it is not an either-or proposition, but rather it is ideal
situation is to have both talks and tutorials on similar topics, but
coordinate with eachother.
My approach was to use two very different systems and show how various
problems can be solved using these approaches. HERMES assumes that all
information is live and also transactional, while the Open Reservation
Management System assumes that information needs to be archived and
reconstructed for specific dates for analytical operations (i.e. what was
the vacancy rate for January 12, 2003 for all rooms with double beds).
