The attribute PropertyName is used to specify the column name of the database table.

This attribute is NOT necessary to store a property in database, but it is necessary if you want to specify a column name that is independent from the name of the property. That’s maybe the case if you want to map your class to an already existing database table.

            [PropertyName("CULTURE")]

            public string CultureKey

            {

                  get { return _culture; }

                  set { _culture = value; }

            }

 The example above stores the property "CultureKey" in a column named "Culture".
