Abstract: This article just introduces the universal- .etion model. it sketches the fundamental :ka$ behind the model and describes a few .gainpies. Other work offers deeper reatment. : Consider the assumptions that are freaently made when talking about niversal-relation systems. These assump- =arch 198 tions must be satisfied by an application for the universal-relation model to be adequate for that application. All data models have such underlying assumptions, although they are very rarely made explicit (Update)
