Databases Reference
In-Depth Information
Notice the set of tabs above the application list. This tab set provides a high-level filter of which applications you
see from all those in your workspace:
All Applications
shows all application types (database and websheet).
Database Applications
shows only those applications that are built on top of a database
schema. These are considered standard APEX applications.
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 applications.
The list of applications you see is actually a style of report called an
interactive report
(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 creating 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, Application 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 customize the way you see this data.
