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.

A data warehouse is a central, integrated repository for historical, enterprise data from multiple business systems. An expanded definition for data warehousing includes business intelligence tools for analyzing the data and OLAP is part of the broader category of business intelligence tools.
