Greetings to all of my friends who work in the area of computerized decision support. This blog is a way for me to share stories from my encounters related to decision support, to comment on industry events, and to comment on other blogger's comments, especially those of my friends on the Business Intelligence Network. I'll try to state my opinions clearly and provide an old professor's perspective on how computers and information technology are changing the world. Decision making has always been my focus, and it will be in this blog as well. Your comments, feedback and questions are welcomed.

It is easy to forget that computers process data differently than we humans do.

Decision support data sources and databases have changed however and new technologies have created a need for new skills. A contemporary database management and theory course must deal with a broad set of topics. Web resources, primarily Wikipedia, meet a need for authoritative, low cost knowledge about databases and data management.
