Virtual schemas
When you bind an array of data to a DataSet’s items or dataprovider property, the data set
only recognizes fields that are top-level items within each row of the array. It does not
recognize items nested within other objects. A virtual schema lets you change how the
underlying data structure is interpreted when bindings are executed. The new structure is
derived using XPath statements. For more information, see “Adding bindings using path
expressions” on page 446.
