Hello,
I gave today a lecture named "database-free applications"[1]. The lecture explain an idea of how to design complex systems and break them apart etc...
The lecture is in English and so does my slide notes, and I think that people here can enjoy the idea as well.

I hope this will help, and feel free to ask me questions in the subject if you have any
Ido
