    <summary>
      <para>
An implementation of <see cref="T:Gda.DataModel" /> based on a hash table.
</para>
    </summary>
    <remarks>
      <para>
Unlike <see cref="T:Gda.DataModelArray" />, this data model implementation stores the <see cref="T:Gda.Row" /> in a hash table.  So it only retrieves from the database backend exactly the requested rows (while in <see cref="T:Gda.DataModelArray" /> you have to retrieve all the rows until the one requested).
