You could use Active Record.

class Person < ActiveRecord::Base
end

>> some_person = Person.new
>> some_person.last_name = 'Kong'
>> some_person.save

etc

Though ActiveRecord is known for being a component of Rails, it can be used
entirely discreetly from Rails.

e.g.

  require 'active_record'
  
  ActiveRecord::Base.establish_connection(:adapter => 'sqlite', :database => ':memory:')

  class Person < Active::Record::Base
  end

All set.
