        public DataRelation(string relationName, DataColumn parentColumn, DataColumn childColumn, bool createConstraints)
        {
            DataCommonEventSource.Log.Trace("<ds.DataRelation.DataRelation|API> {0}, relationName='{1}', parentColumn={2}, childColumn={3}, createConstraints={4}",
                            ObjectID, relationName, (parentColumn != null) ? parentColumn.ObjectID : 0, (childColumn != null) ? childColumn.ObjectID : 0,

            DataColumn[] parentColumns = new DataColumn[1];
