System and method for creating validation rules used to confirm input data

摘要

A graphical user interface is provided for creating a set of validation rules. A form is represented in a tree structure with nodes representing fields to be filled out in the form. Rules are added to the fields using a dialog box and are represented as subnodes of fields. Expressions are added to the rules as subnodes of the rules through a menu. The completed tree structure is translated into a set of validation rules.
