A very important contribution in these years is from workflows. With a workflow, you can develop complex systems in very little time.
An air reservation application is a workflow, for example. There are steps such as the choice of a flight, booking, and confirming the flight that can be configured and then executed without developing much code. Java EE 7 gets a new role for the Java enterprise, giving the opportunity to work with XML files to configure steps to add in web applications.
Schedulers too are part of it and they are finally standard. Frontend technologies now include flows with a strategy very similar to the workflows. Schedulers and flows will be discussed in Chapter 12, Batches and Workflows.
