Powerbuilder Datawindow Object

The Datawindow is an Object designed for working with relational databases. A Datawindow has two components –

the datawindow object and the
datawindow control.

The datawindow object is used to set up the structure of the reports we want. You specify the presentation style, the selection method, the database tables involved as well as the specific columns needed. You also handle the cosmetic effects of your report using the datawindow painter.

Once the datawindow object is created, it gets linked to a window using a datawindow control. The datawindow control is placed in a window object. A datawindow control acts as a placeholder for the datawindow. The datawindow control has a dataobject property. You specify the name of the datawindow object that you want to link to. You develop the script that will manipulate the data in the datawindow control.

We use the datawindow to:

Enter data
Retrieve data
Manipulate data
Validate data
Present data
Export Data

The data object provides powerful display formats and presentation styles.
