4.1.4.Person Entity and Group Entity
Figure – Person Entity and Group Entity
The Person Entity and the Group Entity, both shown in Figure , define the attributes of a Person and a Group, and the relationship between them.
A Person or Group is identified in the NDR by their State (authority) and a state issued ID (state person id / state group id).
A Person may be registered as a Trainer or Owner, and these are maintained separately within Registrations. A Group may be a Syndicate or a Partnership. Each Group consists of number of Members, one of whom is given the role of Manager.
Note that both Person and Group have an identifier assigned by their local authority (shown in Figure as “state person id” and “state group id”). Such identifiers are not guaranteed to be globally unique, so a Person or Group must always be identified by a combination of authority and identifier.
When a Person moves state, they are obliged (within a short period) to register with the authority in their new state. The authority in their new state will update their details in the NDR. This scenario is described in more detail in Section 6.1.1.
When a Person moves interstate the authority of the state the person is moving to must move all the Groups that person is a Group Manager of – in order to allocate new IDs.
As Person and Group are separate Entities within the NDR, they may be updated separately, which could in certain cases lead to inconsistencies. In order to maintain internal consistency, the NDR will perform the following actions:
