Copyright 2009 bSolv. All rights reserved 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 Citizen 2.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

Copyright 2009 bSolv. All rights reserved 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

Note that the systems are decoupled and can have different values for the same data element.
