This recent session at OSDC 2011 Canberra is based on part of an Open Query training day, and (due to time constraints) without much of the usual interactivity, exercises and further MySQL specific detail. People liked it anyway, which is nice! The info as presented is not MySQL specific, it provides general insight in how [...]
Some guidelines to choosing between MySQL’s numeric types, using longitude and latitude as a modelling example.
The No-SQL tag really lumps together a lot of concepts that are in fact as distinct from eachother as they are from SQL/RDBMS.

So far we’ve seen most programming languages as well as CSS and SQL come by. I think it’s a nice example of how “the collective” [...]
