And yet, the question of how to create such a consistent, integrated information resource almost begs a simplistic answer. If that's what you want, you must stop creating duplicates of existing information that have to be managed to consistency in ever shorter time windows, and you must eliminate--or, at the very least, substantially reduce--existing data duplication.
The original data warehouse architecture from 1988 showed the way. It proposed a logically single data store--the Business Data Warehouse--modeled at the enterprise level as the consistent and integrated source of all information for decision making. This simplicity was ultimately lost with the emergence of the layered architecture (with multiple data marts fed from an enterprise data warehouse), due to a combination of database performance and enterprise modeling issues.
Nonetheless, the approach remains valid for the current much-expanded needs for integration. First, model all the information according an enterprise-level model and then implement as far as possible in alignment to that model. This is the approach proposed in a new architecture, Business Integrated Insight (BI2), which for the first time gathers all the information of the enterprise, hard and soft; operational, informational and collaborative into a single component called the Business Information Resource...
