The tables in a dataset are implemented by the DataTable class. This class has Rows, Columns and Constraints properties which consist out of a collection with respectively DataRow, DataColumn and DataConstraint objects. The DataColumn can be seen and implemented as it was a normal database column. It supports all column specifics like AllowDBNull, AutoIncrement, Unique, ...
The DataRow has two special properties, the first one is called RowState. This property keeps the state since the last call of the AcceptChanges method. Possible states are Detached (created, but not in table), Added, Unchanged, Modified and Deleted. The second property is DataRowVersion which tracks different versions of each DataRow. The possible versions are Current, Default, Original and Proposed.
