Beginning Oracle® Application Express

1.5. What Are You Going to Do?

So far, so good. You've got a handle on Oracle Application Express, the tool you will be using to accomplish the task laid out in this book.

That primary task is to build an order entry system from scratch. You will be creating the data structures to hold the order information, loading data into those structures, creating maintenance tools for administrators to use to access and modify this data, and creating a browser-based user interface for your application.

The application itself will have all the features you would expect in a robust application:

• Ability to enter data, while ensuring that the data contains appropriate values

• Ability to search for data, according to user-specified conditions

• Ability to report on that data, both at the detail level and through higher-level approaches, such as graphs and charts

• An easy-to-use, attractive interface that will enhance user productivity
