When we save data, Active Record provides us a method serialize, which helps us to save object params in JSON or YAML format. If we do not work with raw data, it is OK, but if we try to query raw data (for analytics purposes, for example) it becomes a headache. For JSON format it is not so critical, because databases provide functionality for work with JSON data, but for YAML there is no such functionality, which causes troubles for raw data querying.
