We got in the night before things start and have met a few fellow attendees just hanging around the lobby. Gary kindly gave us a lift in to the Brisbane PHP/MySQL group meeting which was well attended.
The presentation and demo was about mongoDB which is a database that stores blobs of structured data expressed in JSON. This would not be impressive if it didn't also have the ability to query and even index the structured content of that data. The use case that comes to mind is where you're storing rich data but don't fully know what you might get.
After Indian dinner Gary drove us up to the top of a hill from where we viewed a panorama of Brisbane.
