2.4.Guiding Principles

The National Data Repository (NDR) is the master repository for greyhound data that is common between GA and the State Bodies.

The following principles are used to guide decisions concerning what data should be stored in the NDR, how it should be named, and how it should be accessed.

#	Principle	Business Impact	Approved By Date
1	The NDR will store the minimum of data that needs to be common between GA and the State Bodies.	GA and each State Body will have to maintain their own data repository for specific needs which are not met by the NDR.
2	The NDR will use naming conventions that are meaningful across jurisdiction boundaries.	Bodies will have to use NDR naming when communicating with the NDR, which may require converting from a local naming convention.
3	Every data item stored in the NDR has an Owning Authority.	Only the Owning Authority of a data item is able to modify the data item. (Note: There are some specific exceptions to this rule, which are specified later in the document.)
4	Regardless of Owning Authority, all data stored in the NDR is readable by GA and every State Body.
5	When data is updated in the NDR, the NDR will internally update other linked data to maintain internal consistency.
6	NDR maintains a single record for each Person, which is maintained when the Person moves from one state to another.
