store = SimpleStore::Memory.new(:people)
store.put(person)

# some moments later...

store.get(1) # => { ... }

Disk Store

person = { :id => 1, :first_name => 'Kris', :last_name => 'Leech' }
store = SimpleStore::Disk.new(:people)
store.put(person)

# some days later...

store.get(1) # => { ... }

Example

require 'virtus'
require 'guid'

class Person
  include Virtus

  attribute :id, String, :default => Guid.new.to_s
  attribute :first_name
  attribute :last_name

  def ==(person)
    id == person.id
  end

class PeopleTable < SimpleStore::Disk
  def initialize
    super(:people)
