Click the [...] button next to Edit schema to open the Schema dialog box and define the data structure of the
						database table to read data from.
            
            In this example, the database table structure is made of four columns,
							id (type Integer, 2 characters long),
							firstName (type String, 15 characters
						long), lastName (type String, 15
						characters long), and city (type String,
						15 characters long). When done, click OK to
						close the dialog box and propagate the schema settings to the next
						component.
