This scenario describes how to use URI query parameters in tRESTRequest to explore data of a database, and send the response via the tRESTResponse.
To do so, you can create two subJobs linked together by an OnSubjobOk connection; this way the two subJobs will be executed sequentially. For more information on Trigger connection, see the Talend Studio User Guide. The first subJob will create and populate the database and the second one will allow to explore the database through the REST service.
