Increasing market competitiveness has led entrepreneurs to require more and more information from Information Technology areas to allow for efficient decisionmaking. Two alternatives to solving this problem are allied in this work: use of Model Driven Architecture (MDA) and Data Warehousing (DW). This research developed and tested a MDA cartridge. It creates scripts for automatic generation and loads DW based databases on the Online Transaction Processing Model (OLTP) through a MDA tool. With the use of this approach any change in the model would be a corresponding change in the scripts without manual rework.
