A normal data web service (Content Service) delivers data when it is asked for it (for example by calling GetNextContentLevel). In contrast the '''Push Service''' is responsible for '''pushing''' data to every client.
The Push Service push service acts as a central data hub and has a set of methods to get the update information, containing the data that must be pushed to the client defined by its [[#Push Criteria|criteria]], by the sequence and by the last known status.
