Oracle Visual Builder: Applications That Outlive Their First Release · Module 2 · The workspace and your first app

ONE PAGE, ONE LIST, ONE SERVICE CALL, previewed and run. DELIBERATELY TRIVIAL, so nothing is buried in requirements. The triviality is the design: an application with real requirements teaches you the requirements, and this one teaches you the tool. THE FOUR STEPS ARE THE FOUR THINGS FROM LESSON 1, IN ORDER. Create the application and a flow with one page. Define a service connection to something that returns data. Add a variable to hold the result. Add a component bound to that variable, and an action chain on page load that calls the service and populates it. THAT SEQUENCE IS EVERY APPLICATION YOU WILL EVER BUILD, AND IT IS WORTH NOTICING WHILE IT IS THIS SMALL. Everything after this course adds pages, components and conditions — and the underlying chain of service, chain, variable, binding is unchanged in an application with a hundred pages.
