Triggers
Triggers are used to link the MDM Hub and the Data Models you define in Talend Studio. You can use Triggers to call specific Processes under certain conditions.
The Triggers you define in Talend Studio enable different services to be undertaken on specific data records.
Then, whenever a business user creates or modifies a data record from Talend MDM Web UI, for example, a Trigger kicks in and the relevant event-based Process is undertaken by Talend Studio.
