IT architecture and set of tools

To support more automated and efficient exchanges of data and metadata, standard tools and an IT architecture are required. In practice, this means that SDMX promotes the use of standard SDMX-compliant formats (such as .xml); it provides the necessary tools to support the Model, to create SDMX-compliant files, to store SDMX-related artefacts, to map and transcode from existing databases, and to validate the structure (and in future the content) of data files; and it provides the necessary architecture to connect IT systems to the SDMX world, enabling data to be shared more easily.

The SDMX tools are described in detail in their own section of the InfoSpace.

The SDMX IT architecture generally follows one of three types of models:

  • the 'push' mode architecture, through which the sending organisations in Member States send their SDMX-compliant files to Eurostat (the receiving organisation) through eDAMIS (Eurostat's single entry point for statistical data and metadata files);


  • the 'pull' mode architecture, through which Eurostat (the receiving organisation) retrieves the SDMX-compliant data files that it needs from the databases of the sending organisations;


  • the 'data hub' architecture, through which users make queries to the databases in sending organisations and retrieve the data directly.
