Lesson 10

Display Data in Web Applications Conclusion

This lesson has shown you only some of the PHP features and capabilities to display data in a Web application. You have seen how DesignTime Controls and command objects can be used together to collect and display the data, as well as how you can add script to extend and customize DTC behavior.
Using the drag-and-drop ease of Design-Time Controls, you can construct many useful Web pages without writing a single line of code. However, you will also find this useful for rapid prototyping, and then later extend the application by adding custom code.


This module introduced you to the following terms:
  1. design time: The mode of operation when the application is being written.
  2. runtime: The mode of operation when the application is running.
  3. initialization script: Commonly used to set initial values of variables, properties, and so on. Initialization code can be executed as soon as the Web page is loaded to make global settings, or in a function or procedure to make local settings.
  4. data-bound DTC: A data-bound DTC is associated with a specific data item. DTCs are not data-bound until this is done. For example, you can drag a DTC onto a page, but it is not bound to anything until it's properties are set.
  5. stored procedures: Stored procedures are like little programs stored in the database and executed on command.
In the next module, you will learn how to work with ActiveX documents.
