ADO ing ADO data (XSD) Constraints to DataSet constraints: Describes the XML schema elements used to create unique and foreign key constraints in DataSet. Generate DataSet relationships from the XML schema (XSD): Describes the XML schema elements used to create relationships between columns in the DataSet.
Understanding the relationship between constraints and Relationships: describes how to implicitly create a relationship when using XML Schema elements to create constraints in DataSet. Inferred DataSet relational structure from XML: Describes the result relational structure (schema) of the DataSet created when the XML element is inferred ).
