✦ Synopsis

The term "data model' is used to describe the conceptual view of how data which purports to model reality is arranged in a computer system. A 'data structure' is the logical view, and a 'file structure' is the actual physical arrangement of the data. Spatial data, as used in geographic intormation systems, gives rise to particular problems in deriving suitable data models and structures because of the diverse sources and applications of the data. This paper discusses some of these problems and puts forward some pragmatic solutions.
