Database Applications from Scratch
When you create a database application from scratch, the wizard offers many interest-
ing options. You can create any number of pages and link pages to different tables of
data. Additional steps give advanced options that, when planned for, are very powerful.
Creating an application from scratch is the method used in the ticketing application ex-
ercise. Here is what to do to begin the creation process:
1. Navigate to the Application Builder, and click the
Create
button to
initiate the Create Application Wizard.
2. Select
Database
as the application type, and click
Next
.
The following subsections describe the remainder of the creation process in detail.
Each subsection contains one or more subsequent steps in the creation process. Read
the descriptions, and follow the steps as described.
Naming the Application
After selecting the Database application option, you're prompted for details of the ap-
plication, as shown in
Figure 5-10
. The application ID, although automatically created,
can be manually set here. Application IDs must be unique across the entire instance of
APEX, so it's best to leave the ID set to the number APEX has assigned.
