The Commissioning Dataset (CDS) Bureau Service is a hosted facility that provides centralised processing of trusts' commissioning datasets through to the Secondary Uses Service (SUS).
Data for the CDS is sent on a quarterly basis via a file created in a predetermined format. The file is processed for the appropriate quarter and is translated into extensible markup language for transfer to SUS.
The CDS Bureau Service also provides a service for re-forming and transmitting data files for those sites whose direct SUS output does not match the expected output formats and prerequisites.
