COMMUNICATION IN SPATIAL DATA MODELLING WORLD IS COMPLICATED BY UNSTANDARDIZED TERMINOLOGY
Data modelling is about abstracting a portion of the real world, as a basis for the design of databases and application. The existing data modelling approaches show important similarities but also emphasis different components thereby using identical or similar terms for some distinct components on the one hand or different terms for similar components on the other hand. In this paper, a number of key-terms, like data model. entity and object will be defined and an overview will be given on the spatial and non spatial modelling actions. Both results will be compared with the terminology used in the Flemish GRB-project and adjusted definitions for the GRB-project will be proposed. At last the difficulties in 2D and 3D spatial modelling due to the absence of standardized spatial data structures, will be highlighted.
