Database Reference
In-Depth Information
Database Applications
shows only those applications that are built on
top of a database schema. These are considered standard APEX applic-
ations.
Websheet Applications
shows only those applications that are websheet-
style applications. These are new to APEX 4, and we'll talk more about
them in
Chapters 11
and
12
.
Packaged Applications
provides a set of ready-to-use applications and
examples that can be installed in the current workspace.
Figure 2-9
shows one application in the workspace named Sample Master Detail.
However, there isn't much information about it other than its name, the Application ID
(107), and the fact that it's a packaged application. This is where you begin to see the
beauty of what APEX can do, not only in the developer UI, but also in your applica-
tions.
The list of applications you see is actually a style of report called an
interactive re-
port
(IR). IRs allow you to customize how reports and their contents are displayed. IRs
are used throughout the APEX development interface and can also be used when creat-
ing your own applications. They're extremely powerful tools, and you'll use them a lot.
On the right side of the page are four regions that show About information, Applica-
tion Builder-related tasks, recently edited applications, and a link to the Application
Migration Wizard. You deal more with these later; for now, you want to drill in to see
the details of an application.
The Application Home Page
Clicking any one of the applications listed drills into the Application home page, as
shown in
Figure 2-10
. This page is very similar to the Application Builder home page,
but it shows all the pages in a specific application. Again, it uses an IR, so you can cus-
tomize the way you see this data.
