Lifecycle Technology Track
On the Kimball Lifecycle roadmap in Figure 17-1, the business requirements definition is followed immediately by three concurrent tracks focused on technology, data, and BI applications, respectively. In the next several sections we’ll zero in on the technology track.
Technical Architecture Design
Much like a blueprint for a new home, the technical architecture is the blueprint for the DW/BI environment’s technical services and infrastructure. As the enterprise data warehouse bus architecture introduced in Chapter 4 supports data integration, the architecture plan is an organizing framework to support the integration of technologies and applications.
Like housing blueprints, the technical architecture consists of a series of models that unveil greater detail regarding each major component. In both situations, the architecture enables you to catch problems on paper (such as having the dishwasher too far from the sink) and minimize mid-project surprises...
