My first Publication Agile-Data-Warehouse-Design-eBook | Page 18

Introduction The note takers are the members of the team who always read the full instructions before they use that new gadget or technique. They’re always here to tell you to “make a note of that” when there is extra information on the current topic. The agilists will let you know when we're being particularly agile. They wave their banner whenever a design technique supports a core value of the agile manifesto or principle of agile software development. These are listed in Appendix A. The modelstormers appear en masse when we describe collaborative modeling and team planning, particularly when we offer practical advice and tips on using white- boards and other inclusive tools for modelstorming. The scribe appears whenever we introduce new BEAM ✲ diagrams, notation con- ventions or short codes for rapidly documenting your designs. All the scribe’s short codes are listed in Appendix B. The agile modeler engages with stakeholders and facilitates modelstorming. She is here to ask example BEAM ✲ questions, using the 7Ws, to get stakeholders to tell their data stories. The stakeholders are the subject matter experts, operational IT staff, BI users and BI consumers, who know the data sources, or know the data they want—anyone who can help define the data warehouse who is not a member of the DW/BI develop- ment team. They are here to provide example answers to the agile modeler’s ques- tions, tell data stories and pose their own tricky BI questions. The bookworm points you to further reading on the current topic. All her reading recommendations are gathered in Appendix C. The agile developer appears when we have some practical advice about using soft- ware tools or there is something useful you can download. The head scratcher has interesting/vexing DW/BI problems or requirements that the data warehouse design is going to have to address. The pattern users have a solution to the head scratcher’s problems. They’re going to use tried and tested dimensional modeling design patterns, some new in print. XIX
