About displaying and validating data
When DataWindow Designer generates a basic DataWindow object, it
uses the extended attributes defined for the data and stored in the extended
attribute system tables.
For more information about the extended attribute system tables, see
Appendix B, “The Extended Attribute System Tables.”
In the Database painter, you can create the extended attribute definitions
that specify a column's display format, edit style, and validation rules.
In the DataWindow painter, you can override these extended attribute
definitions for a column in a DataWindow object. These overrides do not
change the information stored with the column definition in the extended
attribute system tables.
