The primary purpose of national data sets is to enable conformant health information to be generated across the country, independent of the organisation or system that maintains it. In achieving this, the Health and Social Care Information Centre will enable healthcare professionals to measure and compare the delivery and quality of care provided and to support them in sharing information with other health professionals and organisations.The primary purpose of national data sets is to enable conformant health information to be generated across the country, independent of the ORGANISATION or system that maintains it.

   CDS TYPES
   
   The Commissioning Data Set is the basic structure used for the submission of commissioning data to the Secondary Uses Service and is designed to be capable of individually conveying many different Commissioning Data Set structures encompassing Accident and Emergency Attendances, Out-Patient Attendances, Future Attendances, Admitted Patient Care and Elective Admission List data etc.

   Commissioning Data Set Messages have been defined in specific components known as a CDS TYPE. Each CDS Type as configured into the Commissioning Data Set Message carries only one specific Commissioning Data Set Type, an examples being the Finished Consultant Episode Commissioning Data Set Type etc. Each Commissioning Data Set Type as configured into the Commissioning Data Set Message carries only one specific Commissioning Data Set Type, an examples being the Finished Consultant Episode Commissioning Data Set Type etc.
