Citizen360 – Data Record Concepts
The same person may be in the system several times because they are from several source systems, e.g., DHS, DOR or DSS There is no conflict in this situation – but it is not what is
desired
We identify Citizens using any one of three mechanisms:1. The key used by the source system that provided the Citizen2. A Master Index (optional)3. An internal identifier
Identity Resolution processes exist to find possible people matches
When People are linked/merged: The detailed data elements are moved under a common
citizen “header record” Source systems are not forced to have the same values –
they are still decoupled

Data is kept uniquely by Source-System
The search found 5 different records from 5 different systems
3 of the 5 records are linked across the source-systems – they have the same Master Index value
The following Citizen Search screen illustrates the concepts

There are 3 citizen “header records” in our example…
The first “header record” has data from three different systems.
Note that the systems are decoupled and can have different values for the same data element.

Merging does not change the data – it is still held by Source System

Master Index HistoryValue: 10001340065
Master Index HistoryValue: 1000130073
We can continue to use any of the original/historic “master index” values to reference the citizen
Based on Identity Resolution processes we may decide to merge other records…
The data is still unique by source system - but we now know that it is for a common citizen
