Discovery is based on the hypothesis that; If health related data is brought together at the level of the individual in close to real time, and stored together at the level of a medium size residential population, and made available via a common data model as part of a common ontology, and then subsequently used for individual and population based decision support, great benefits to health can accrue.

Discovery consists of a set of technology components that link near real time data from millions of records from thousands of provider organisations, as well as an information model consisting of a set of ontologies and a common data model.

* Data on individuals are held in a single common data model with data values represented by a super ontology composed of the world's leading health ontologies.
* Data in Discovery is submitted by health providers who provide primary, secondary, and urgent care services to patients or clients.
* Data is kept up to date in close to real time - at worst within 24 hours; see [[Latency of extract data feeds]] for more details.

Discovery forms the basis of an NHS owned data service called the Discovery data service (we like nautical things) , operating across the city of London, covering 3 ICSs and a residential population of 7.5 million citizens. The service seeks to use data as close as possible to its original entry form as entered by health professionals or the citizen themselves, and to use that data as close to real time as the publishers of that data can make available.

These articles describe the various technologies underpinning the Endeavour and Discovery open source systems and related operational services which are currently live.

Discovery Data Service and information model

Discovery is based on the hypothesis that; If health related data is brought together at the level of the individual in close to real time, and stored together at the level of a medium size residential population, and made available via a common data model as part of a common ontology, and then subsequently used for individual and population based decision support, great benefits to health can accrue.

Discovery consists of a set of technology components that link near real time data from millions of records from thousands of provider organisations, as well as an information model consisting of a set of ontologies and a common data model. All the technologies that have been developed are open source and available for anyone to use.

Discovery forms the basis of an NHS owned data service called the Discovery data service (we like nautical things) , operating across the city of London, covering 3 ICSs and a residential population of 7.5 million citizens. The service seeks to use data as close as possible to its original entry form as entered by health professionals or the citizen themselves, and to use that data as close to real time as the publishers of that data can make available.
