NODE is a non-profit group of DBMS professionals who meet several times a year in the Portland area to discuss various aspects of IBM's DB2 family of data management software.

Welcome to NODE

For many years, NODE has provided and continues to provide a free forum for exchanging knowledge about DB2, both on the mainframe and on LUW platforms. Membership in NODE is open to the public and free of charge; the only requirement is a desire to learn or to share your knowledge with others. NODE meetings typically take place in the Portland metropolitan area (specific locations vary), last for three to four hours, and feature two or three technical presentations that are relevant to DB2 administrators, database application programmers, or data modelers.

NODE meetings are coordinated by Fred Sobotka of FRS Consulting, Cathy Taddei of PacifiCorp,and Catalin Comsia of IBM.
