Abstract:
The federation of data sources and the definition of pivot models are strongly interrelated topics. This paper explores the difficulties of a mediation solution based on XML architecture and the concept of Master Data Management. In this solution, pivot models use the standard XML Schema allowing the definition of complex data structures. To date, the graphical modeling of XML Schema models is not standardized. The introduction of a models definition formalism is a mean to make modeling more accessible. UML is a modeling object language which is more and more used and recognized as a standard in the software engineering field, which makes it an ideal candidate for the modeling of XML Schema models. In this purpose we introduce features of the UML formalism, through a profile, to facilitate the collaborative definition and the exchange of these models, and to introduce the capacity to express semantic constraints in XML models. These constraints will be used to perform data factorisat
ion and to optimise data operations.
