The SOA Forum 2006 of Nikkei Business Publications Inc. took place at the end of October 2006 and was a great success. With more than 500 participants from around the world, the conference was completely sold out – more than 300 registrations could not be accepted. Dr. Dirk Krafzig provided information on the basics of SOA in a keynote speech. His remarks met with particular interest among Japanese system integrators.
