2. Quote of the Week
How many software programs are mathematically provable. And yet everybody still writes software and for the most part it works. Relational theory and SQL was very important for establishing a standard across vendors to a point. And yet switching relational database vendors is still very expensive proposition because the standards don't address the features that users need and use everyday that are not part of the standard. At the heart of the system the relational model can still be enforced. But a product lives and dies not on whether it is mathematically provable but it's features set, efficiency and cost to develop in.

3. To Laugh or Cry?
Please help with my data model design
If this was student homework, it is an excellent example of how database management should not be learned and a validation of the substitution of the "cookbook approach" for education. Ironically it's in the forum's section "Relational theory". Had theory been taught, such questions would have not been asked. 

4. Two online exchanges I participated in
Predictable--it was just a matter of time. My latest post at All Analytics is quite apropos: Real Data Science: General Theories of Data.
In this context, consider In Silicon Valley, age can be a curse.

5. And now for something completely different

Not entirely unrelated:
Facebook boosts connections, not happiness study
The Curse of Self-Service (h/t Davide Mauri)
