“…The two elements (UML model and the Constraint Decision Table ) do not make a compact structure and the propagation of updates on one element to the other element needs to be handled explicitly and carefully. The model reader does not find easily the connection between the components of the UML model and the constraints in the Constraint Decision Table . Another approach that is sometimes used to express spatial relationships in UML models of spatial data is to use OCL (Object Constraint Language) constraints as presented in Belussi et al (2004) and Pinet et al (2007). OCL has a high expressive power (Warmer & Kleppe, 2003) but we argue that the textual description of OCL constraints makes the model less understandable by the model readers and writing OCL constraints requires the database designer to master OCL syntax.…”

Spatial databases form the foundation for a Spatial Data Infrastructure (SDI). For this, a spatial database should be methodically developed to accommodate its role in SDI. It is desirable to have an approach to spatial database development that considers maintenance from the early stage of database design and in a flexible way. Moreover, there is a lack of a mechanism to capture topological relations of spatial objects during the design process. This paper presents an approach that integrates maintenance of topological integrity constraints into the whole spatial database development cycle. The approach is based on the concept of Abstract Data Types. A number of topological classes have been identified and modelling primitives developed for them. Topological integrity constraints are embedded into maintenance functions associated with the topological classes. A semi-automatic transformation process has been developed following the principles of Model Driven Architecture to simplify the design process.

“…The GeoUML Methodology (Belussi et al, 2006) and the GeoUML Tools (Belussi et al, 2009) described in this paper have been developed in order to support the management of a geographical Conceptual Schema and to perform the automatic validation of the conformance of a Data Product to a given Conceptual Schema. The fundamental principles of this development have been:…”

ABSTRACT:A huge amount of geographical datasets are becoming available in distributed environments like Spatial Data Infrastructures (SDI). These datasets are very heterogeneous since they come from different independent sources and surveys and are structured in different formats. In the context of a national SDI that needs to assure an adequate quality level of the data it provides, it is necessary to face the problem of data validation in an uniform way independently from the chosen implementation technology. In this paper we present the tools and methodology for data validation which have been developed to support the construction of the Italian SDI. These tools are conformant to the relevant ISO 19100 and Open Geospatial Consortium (OGC) standards.

The ISO TC 211 standards have defined a set of formal models for\ud the conceptual modeling of spatial data using the Unified Modeling Language\ud (UML) and the geometry approach adopted by the ISO spatial data model and\ud by the Geographic Mark-up Language (GML). This approach aims to define a\ud conceptual model for the design of geographic databases and for the geospatial\ud interoperability of heterogeneous spatial databases. The ISO standards are however\ud complex and counterintuitive in dealing with spatial integrity constraints,\ud which are fundamental for the expressiveness of a conceptual model in the geographic\ud application domain. This paper improves the ISO approach by proposing\ud a framework which allows the definition of powerful, easy to use, and ISO\ud conformant modeling abstractions for topological spatial constraints. These\ud modeling abstractions have been incorporated in the definition of the GeoUML\ud conceptual model used in the Italian IntesaGIS project for the definition of the\ud “core” database of the Italian Spatial Data Infrastructure
