Data Warehouse for FER e-Invoice System

An e-invoice is the most widely used electronic document in the world. Although it covers only one segment of the entire supply chain, the e- invoice has a central role in the development of electronic business. An electronic invoicing system named an FER e-invoice is built at the University of Zagreb Faculty of Electrical Engineering and Computing (FER). The FER e- invoice system contains business processes that should be monitored and analyzed. Therefore, a data warehouse, containing data extracted from e- invoice XML documents, has been developed. Multidimensional model of the data warehouse consists of two fact tables, one for the invoice heading and one for the invoice items, and of 14 dimensional tables. In this paper the developed data warehouse is presented.
