Useful advice from Tom Armitage on the exploratory development approach required when starting to build a project against a large, complex dataset. Tips include making sure you have a REPL to hand and using tools like gRaphael to generate graphs against pretty much everything, since until you’ve seen their shape you won’t know if they are interesting or not.
