I have to do a data warehousing project. What's the best way to start? What should I do first?


Sid Adelman's Answer: The first thing to do is find a strong sponsor, someone with a budget, a need for the information a data warehouse will provide and someone who has an important position in your organization. Next, start to set realistic expectations including a reasonable schedule.

Larissa Moss's Answer: I suggest the first two steps are: 1. Training in what data warehousing is and what it is not, and 2. assessing your current environment for its readiness in terms of technical as well as non-technical infrastructure, such as methodology, staffing, skills, data warehouse administration, standards, budget, prioritization of projects, current vs. desired technologies, tools, etc.
