| heal.abstract |
An extension to the relational model is defined for the management of spatial data. The model adopts a radically new methodology for the formalization of three spatial data types, point, line and surface, based on a definition for spatial quanta. A relational algebra is next defined whose operations are closed and their result is defined uniquely. Most important, the operations represent adaptations of others that had been used in previous research for the modeling of temporal data. Hence, the model applies uniformly to the management of conventional, spatial and temporal data. |
