DuckFeet’s guts are SQLicious, and built as DBIx::Class classes, sprinkled with wonderfully tooth-decaying DBIx::Class::Candy on top. In the repo, it’s all under the DuckFeet::Schema namespace. For the time being, there is only a handful of tables (hits, uris, referers, agents and hosts), but it should be easily extendable to add any type of information we might desire to throw in, but it should be easily extendable to add any type of information we might desire to throw in.
