Answer / dfd

A DiffGram is an XML format. It is used to identify current
and original versions of data elements. A DataSet may use a
DiffGram format to load and persist the contents, and
further to serialize its contents for porting across a
network connection. Whenever a DataSet is written as a
DiffGram, the DataSet populates the DiffGram with all the
important information to accurately recreate the contents.
Note that schema of the DataSet is not recreated. This
includes column values from both the Current and the
Original row versions, row error information, and row order.
