ABSTRACT
An enterprise architecture can be thought of as a map of the interactions of the individual systems that comprise it. One of the systems expressed in Figure 7.2 is the business intelligence and analytics system. Typically, these systems handle business proprietary and sensitive data about the performance, strengths, and weaknesses of business execution. Therefore, business intelligence systems are usually not exposed to untrusted networks and to untrusted parties. The Digital Diskus data analysis and business intelligence system exists only on the company’s internal network. No portion of the system is exposed on either of the external zones (Internet and Extranet).
