[[File:IC Push Notification Service 01.png|thumb|220px|Push Service]]
A normal data web service ([[UBIK Content Web Service]]) delivers data when it is asked for it. In contrast the '''Push Service''' is responsible for '''pushing''' data to every client.
The 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.
