Understanding how data is packaged in these systems hinges on what the message key actually includes. A message key defines which data elements travel with a record, and how complete those elements are in a given exchange.

That design makes its message key capable of carrying a comprehensive set of information about a person, vehicle, or incident whenever access is authorized.
