Creating a Trigger

Triggers are rules for transforming data. You can easily define Triggers on specific business entities/elements from Talend Studio.

Parameters to set when defining Triggers include:

• selecting the business entity you want to Trigger the Process on,

• setting conditions on its content,

• deciding the execution mode,

• selecting the service to Trigger,

• setting the service parameters.

Prerequisite(s): You have already connected to the MDM server from Talend Studio. You have the appropriate user authorization to create Triggers.

For this example, a data model called Product has been created in Talend Studio. This data model has two business entities: Product and ProductFamily. Several attributes have been created in the Product entity including Price and Family. For further information about how to create a data model, see Setting up a data model.

A Process has been created and named Call_Job. One service has been defined in this Process to launch a validation Job whenever a price of an item that belongs to a specific family has been changed through Talend MDM Web UI. For further information about how to create such a Process, see Creating a Process from scratch.

What is left to be done now is to create a Trigger and configure it to launch the Call a Job from MDM Process that will by turn launch the Talend price validation Job.

The sub-sections below explain in detail the procedures necessary to complete the creation of such a Trigger.
