Once you understand the type of functionality available in a sample application, the next step is to learn more about the construction of each page. An efficient way to speed up the learning process is to analyze and deconstruct the pages in the demonstration applications. If you happen to break something, you can quickly delete the demonstration application and install it again. See "Updating a Previously Installed Sample Database Application".
You edit existing pages in an application, add pages to an application, or create entirely new applications using Application Builder.
