The query gateway is a web based application that provides the back end for executing queries.
The query gateway which exposes a query API, accepts queries, runs those queries against the patient data, and returns the results of the query back to the query composer.
hQuery will run properly on OSX and various distributions of Linux
hQuery will also run on Windows, however, there are some minor limitations to functionality and performance.
