A configuration is an environment or workspace where you connect imported models to each other to build a global schema of the enterprise information system.

You have been assigned an object role with at least the Metadata Viewing capability.

A valid configuration consists of a collection of model versions, mapping versions, glossaries and stitchings. The model versions relate to data stores and data processes that have been imported into Talend Data Catalog.

A configuration may be understood as any of the following:
  • Repository workspace is a collection of repository objects to be analyzed together (search, browse, reports, etc.) as a technical scope, or business area under the same access permission scope.
  • Enterprise architecture is a collection of data store models (ODS, data staging areas, data warehouses, data marts, etc.) and data process models (ETL/DI, and BI) connected together through data flow stitching.
  • Design workflow is a collection of conceptual, logical and physical models connected (semantically stitched) together through semantic mappings modeling the design process.

A configuration may have one or more versions. Configuration versions may be understood each as a different collection of versions of repository objects. You can define several configuration versions, each containing various versions of the repository objects.

As a result, you can perform:
  • Historical analysis using configuration versions containing older versions of models which were deployed at some time in the past.
  • What-if analysis using configuration versions containing the versions of models which may be deployed in the future.
