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:
Procedure
- Create a data model containing one or multiple business entities. A business entity can be a supplier, a country, a customer, etc.
- Define the corresponding data container for the data model in the MDM Hub where the master data is to be persist.
- 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.
- Design one or more Triggers, rules for transforming data, that enable the event-based Processes to be undertaken on specific data records.
Results
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).
