the parcel and ownership tables is one-to-one, each desti parcel can be displayed with a unique symbol. 1f the cels relationship is many to one, one or more par- caust the desti the can be displayed with one symbol. But if relationship is one- to many, data display becomes a problem because it is not right to show a multi 83. owner parcel with an owner who happens to be the first on the list. (One solution to the problem is to use a separate symbol design for the category of table multi owner parcels.)
