Talend Studio enables you to centralize the details of one or more MDM connections under the Metadata folder in the Repository tree view. You can then use any of these established connections to connect to the MDM server.
For more information on working with Talend MDM, consult the MDM Part of this guide, which starts with Master Data Management: Concepts and Principles.
You can also set up an MDM connection the same way by clicking the icon in the Basic settings view of the tMDMInput and tMDMOutput components. For more information, see tMDMInput and tMDMOutput at https://help.talend.com.
According to the option you select, the wizard helps you create an input XML, an output XML or a receive XML schema. Later, in a Talend Job, the tMDMInput component uses the defined input schema to read master data stored in XML documents, tMDMOutput uses the defined output schema to either write master data in an XML document on the MDM server, or to update existing XML documents and finally the tMDMReceive component uses the defined XML schema to receive an MDM record in XML from MDM triggers and processes.
