Hello, I’ve put together a (free, open source) SQL database schema / tables and ActiveRecord models for CryptoKitties. Still early and suggestions more than welcome on how to make it better, easier, faster, etc. The models incl. Kitty (of course), Gene, Trait and more. The idea is to make queries easy (thus, all 48 genes of a kitty in a “flat” genes tables along with all others). Find the source at the Copycats project page. Cheers. Prost. PS: You can read-in all 500000+ kitties using the Kitties on the Blockchain public dataset in comma-separated values (CSV) format in blocks of a thousand kitties each.
