Executing a PDI transformation as part of a Pentaho process
Everything in the Pentaho platform is made of action sequences. An action sequence is, as its name suggests, a sequence of atomic actions that together accomplish small processes. Those atomic actions cover a broad spectrum of tasks, for example, getting data from a table in a database, running a piece of JavaScript code, launching a report, sending e-mails, or running a Kettle transformation. For this recipe, suppose that you want to run the sample transformation to get the current weather conditions for some cities. Instead of running this from the command line, you want to interact with this service from the PUC. You will do it with an action sequence.
