ABN AMRO was formed from a series of mergers and acquisitions. Their origins date back more than three centuries.
ABN AMRO serves its customers in retail, private banking and corporate banking, mainly in the Northwest of Europe. In the Netherlands, customers are offered an extensive and complete package of products and services through various channels, such as the Mobile Banking app and Internet Banking.


Following the merger between ABN AMRO Bank N.V. and Fortis Bank Nederland N.V. mid-2010, ABN AMRO started the migration of Fortis administration to the target systems of ABN AMRO.

Data eXcellence, on behalf of ABN AMRO, developed a framework for this data migration with which the migration of the credit products can be automatically validated. The validation results serve as a basis for adjusting the migration approach.

In 1964, the Netherlands Trading Society (NHM) and Twentsche Bank announced that they would merge into Algemene Bank Nederland (ABN). In that same year, Rotterdamsche Bank and Amsterdamsche Bank too announced that they would merge (Amro).
Twenty-seven years later, these two largest general banks in the Netherlands merged and continued as ABN AMRO. The pooling of resources and international economies of scale were the main motives.
