This paper has proposed a Graph – semantic based conceptual data model for XML based data Warehouse (DW) system called GXDW model, to conceptualize the different facets of multidimensionaldatabases which may contain semistructured data. The model is an extension of object oriented paradigm and defines a set of graph based formal constructs, variety of relationship types with participation constraints. It is accompanied with a rich set of graphical notations those are used to specify the conceptual level design of semi-structured data based DW system. The proposed approach facilitates modelingmultidimensionaldata with the existence of irregular, heterogeneous, partially organized and unordered data set. Moreover, a transformation mechanism also has been proposed for guiding the transformation of GXDW model schema into the related set of XML documents.
