MDM working principles


About this task

From Talend Studio, you can define the rules that master data has to follow.

A typical sequence of setting governance rules in Talend Studio involves the following steps:


  1. Create a data model containing one or multiple business entities. A business entity can be a supplier, a country, a customer, etc.
  2. Define the corresponding data container for the data model in the MDM Hub where the master data is to be persist.
  3. Design one or more Processes that perform transformations, data validation and other tasks. Processes usually call a sequence of available plug-ins to project data from the source system to a defined data container (MDM Hub). During projection, the data is transformed, cross-referenced if needed and validated against the entity model.
  4. Design one or more Triggers, rules for transforming data, that enable the event-based Processes to be undertaken on specific data records.


After projection, the MDM Hub holds valid data (model compliant data) that a data steward or a business user can query and/or extract via Talend MDM Web UI.

Before a given business user is able to extract and query valid master data via the web-based User Interface, you need to create one or more Views in Talend Studio that specify:

  • which records of an entity a business user has the right to search,

  • which records of an entity a business user has the right to view,

  • optionally which conditions should the content meet to be delivered as the result of a search (content filters).
