            // Creates a new DataStore object.
            var course = new DataStore("d_course", _context);

            // Gets the DataWindow.Table.UpdateKeyInPlace property.
            bool updateKeyInPlace = course.DwMeta.DataWindow.Table.UpdateKeyInPlace;

            Console.WriteLine("UpdateKeyInPlace = {0}", updateKeyInPlace);

            /*This code produces the following output:
