Definition
“Spatial databases” consist of large groups of data structured in a way to represent the geographic features of interest to the users of a system. Spatial database models are schematic representations of these data. Database models are created to design and document the system, to facilitate communication and to support programming. They are created using CASE tools (computer‐assisted software engineering). CASE tools support schema drawing, dictionaries and code generation. Database schemas are typically represented with a graphical language such as UML (Unified Modeling Language; see http://www.uml.org and [11]).
“Database models” can represent (1) users' real-life views of the data of interest, (2) developers' views of the potential organization of these data for a family of technologies, or (3) their final implementation on a specific platform. For example, in...
