Turntable

The hip-hop Ruby database

Christian Koch [e-mail]

Turntable is a pure Ruby implementation of a relational database, similar in spirit to SQLite. Unlike Sequel or any other object-relational mapper, Turntable is built with Ruby from the ground up, and implements Rubyisms whenever possible. It never goes anywhere near SQL.

Turntable databases include the Enumerable mixin, so all the methods available there are also available for you:

turntable. select { |film| film[:title] =~ /\AG/ }. sort_by { |film| film[:year] }. reverse. detect { |film| film[:director] == "Francis Ford Coppola" }

Turntable is released under a simplified BSD-style license.
