What exactly is simple inheritance? With what I have below, it doesn't
create any addiotional tables. How will I be able to query only votes
for Items?

Thanks!

Vote:
  tableName: votes
  actAs:
    Timestampable:
      created:
        name: created_at
        type: timestamp
        format:Y-m-d H:i:s
      updated:
        disabled: true
  columns:
    id:
      unsigned: 0
      primary: true
      notnull: true
      autoincrement: true
      type: integer
    user_id:
      unsigned: 0
      primary: false
      notnull: false
      autoincrement: false
      type: integer
