In ATEbank I created the DW/BI system from scratch. It was placed at the center of the bank as the only reference point for information/analytics. Integrating several source systems, it had been used to serve all the levels of the bank (Branches - Central Divisions - Top Management - CEO) as well as external stakeholders such as European Central Bank, Central Bank of Greece etc. As the top achievement I consider the change of the mentality of the people of the bank and the comprehension of the importance of such a system.
