The proposed model is defined by first-order logic. The answers to a query contain both sure answers and maybe answers. To guarantee that the manipulation power of the proposed model is as good as that of the classical relational model, we prove that the classical properties of the database, uniquely determined and well-defined relational algebra, are preserved in our proposed model.tku_id:000093355; 000081863en1016-2364國內否TWN<links><record><name>機構典藏連結</name><url>http://tkuir.lib.tku.edu
