Abstract
Over the last few years, NoSQL systems are gaining strong popularity and a number of decision makers are using it to implement their warehouses. In the recent years, many web applications are moving towards the use of data in the form of graphs. For example, social media and the emergence of Facebook, Linkedln and Twitter have accelerated the emergence of the No SQL database and in particular graph-oriented databases that represent the basic format with which data in these media is stored. Based on these findings and in addition to the absence of a clear approach which allows the creation of data warehouse under NoSQL model, we propose, in this paper, an approach to create a Graph-oriented Data warehouse. We propose the transformation of Dimensional Fact Model into Graph Dimensional Model. Then, we implement the Graph Dimensional Model using java routines in Talend Data Integration tool (TOS).
