Data Distribution

Understanding Data and Content in HL7 Messages

The Data Distribution feature tells you about the data values in a field.  For instance, it helps you to quickly figure out what codes are used in a specific field or how often a specific code is used.
Also, Data Distribution helps you analyze how one field can impact other fields in terms of data and content.  This way, you could get the list of lab result codes for each lab request codes within a set of sample messages.

All charts and tables can be copied and pasted to Word and Excel.
