The Home page contains four main regions:

  • Sales Quota for this Month

  • Top Customers

  • Top Products

  • Top Orders by Date

Sales Quota for this Month demonstrates the use of a Flash Dial chart. This chart displays a value based on an underlying SQL statement. Although not demonstrated in this example, you can enable an asynchronous refresh by editing the attributes of a Flash chart.

Top Customers is a report based on a SQL query and displays a subset of the information that appears on the Customers page. Users can link to additional details by clicking the customer name or by clicking the View Customer icon (a right arrow) in the upper right corner of the region.

Top Products is also a report based on an SQL query. This report displays a subset of the information that displays on the Products page. Users can link to product details by clicking the product name or by clicking the View Products icon in the upper right corner of the region.

Top Orders by Date displays orders by date and order amount. Users can view the Orders page by clicking the right arrow in the upper right corner.

Sample Database Application is a simple HTML region that displays static text. You can create this type of region to display explanatory information to users.

Viewing Pages in Printer Friendly Mode

Clicking Print in the upper left corner of the page displays the current page in Printer Friendly mode. When in Printer Friendly mode, the Application Express engine displays all text within the HTML form fields as text.

To enable your application to display in Printer Friendly mode, you must create and then specify a Print Mode Page Template on the Edit Application page.

Modifying Product Portal

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.
