3.1.Business Context
The National Data Repository (NDR) is the master repository for greyhound data that is common between GA and the State Bodies.
The NDR also acts as a mechanism for GA and the State Bodies to publish data changes to other parties. Whenever GA or a State Body update locally held data, they may also choose to push any relevant changes to the NDR. The NDR, in turn, publishes any such changes as events, which can then be picked up by other interested parties.
