Un système de contraintes d'intégrité OCL pour les bases de données spatiales. Application à un système d'information pour l'épandage agricole

Abstract : It is important to ensure data quality in GIS applications. Also, from their conception, a constraint language can be combined with conventional modeling languages ​​to specify formally the alphanumeric and spatial constraints that language must comply. The purpose of this thesis was to propose a constraint language to specify the conditions that agricultural system must meet to be consistent. For this, we have expanded in spatial OCL, the language of duress with UML. Through the integration of spatial types and specification models of topological relations, the proposed extensions allow the description of spatial constraints from a UML class model of extended space. The expressiveness of each proposed extension of OCL has been studied. These languages ​​have been implemented through the extension of a code generator, and experienced OCL2SQL Cemagref as part SIGEMO
