This section makes an exception to that rule by covering Application
Express (commonly known as ApEx), a development tool that comes with the
Oracle database and simplifies HTML application development. We discuss ApEx
here because the tool can be downloaded for free and installed on an Oracle database
installation without any other software, and because the tool creates applications by
generating PL/SQL packages that are stored in the Oracle database.

The Application Express product was previously known at HTML-DB, which itself
sprung from WebDB. All of these products had the same basic development methodology
??”browser-based wizards that helped youcreate application components that
also ran in a browser.
ApEx creates components as PL/SQL packages that produce the browser-based user
interface. ApEx components can include forms, reports, and charts. The ApEx
development environment gives youthe ability to create rich applications, and that
environment is too robust to fully describe in this brief section.
