Marcin Gorawski, Michał Piekarek


Theoretically data extraction process is a simple task, but practice shows that this process may take even up to 70% of the overall time destined for data warehouse (DW) realisation. Designers engaged in extraction process often use specialised software dedicated to specific warehouses. In this paper we present project and realisation of developmental environment that minimises time and efforts related with DW.
