Modelling geospatial application databases using UML-based repositories aligned with international standards in geomatics

Abstract

This paper presents the result of recent work on the use of geospatial repositories to store the conceptual content of object oriented application database schemas and dictionaries aligned with international standards in geographic information (ISO/TC 211 and OGC). According to software engineering and database concepts, a geospatial repository can be defined as a collection of (meta) data structured in a manner to provide information about the semantics, geometry, temporality, and the integrity constraint of data stored in a geospatial database. For the last 6 years, ISO/TC211 and OGC have been developing standards about geographic information to enable access and interoperability of geographic information; parts of these standards impact directly on geospatial repositories. Our work demonstrates that it is possible to develop a geospatial repository aligned with these standards and to implement it in a UML-based visual modelling tool.

A framework for the trajectory data warehouse conceptual modeling support: a mobile hospital trajectory case study

“…Several works (Lujàn-Mora et al 2006;Wagner and Eindhoven 2002;Grassi et al 2004;Zubcoff and Trujillo 2007;Zubcoff et al 2009;Brodeur et al 2000;Spaccapietra et al 2008) adopted UML profiles to catch specificities of a universe of discourse. In fact, in (Zubcoff et al 2009) the proposed profile is used for the oriented agent modeling.…”

Extending UML for trajectory data warehouses conceptual modelling

“…Several works [10] [15] proceeded by UML profiles to represent their models. In fact, in [11] the proposed profile is used for the oriented agent modeling.…”

“…In [14] authors propose a profile to model data mining with the temporal series in the data warehouse. In [15], authors extended UML to introduce new stereotypes and icons to handle spatial and temporal properties at the conceptual level. This led to the visual modeling tool so called Perceptory.…”

Precise design of environmental data warehouses

“…In the environmental field, it will be vital to pay more notice to modeling and storing geographical data. To this end, the proposals of Malinowski and Zimanyi about multi-dimensional modeling (2008) may be considered, together and more generally with UML extensions for Geographical Information Systems (Brodeur et al 2000;Friis-Christensen et al 2001;Miralles and Libourel 2007;Pinet et al 2005). The automatic production of mechanisms for checking OCL integrity constraints in data warehouses will make it possible to compensate for the current lack of concrete ways to check the quality of integrated data.…”
