Welcome to Grant Castner's teaching website. I formerly taught a number of information systems courses (including eBusiness and eCommerce) in the Lundquist College of Business at the University of Oregon. I am currently president of Castner IT LLC, a company that provides technology consulting services. This website serves a dual purpose. Not only does it provide links to relevant course materials, it also illustrates concepts and technology used in those courses. Please e-mail me if you have any questions or suggestions about the site.
