Deploying an Onyx Questionnaire

The Onyx Questionnaire and the PMI Lookup

Onyx uses a web service to access the Patient Master Index (the PMI). This web service is provided by the pmi-lookup. The Onyx questionnaire is currently installed alongside the pmi-lookup; ie: within the same instance of tomcat.

This seems sensible as we have only one questionnaire at the moment, and we don't know what it would entail to run more than one questionnaire at the same time. These ideas will have to be worked out in time. For the moment, we are sticking to using one tomcat instance.

The PMI Lookup uses an SqlServer table function invocation in JDBC to retrieve demographic data. For testing Onyx in a situation where SqlServer is not available, there is a development version of the PMI Lookup which uses a MySql database.
