This model is a sometimes referred to as a Virtual Data Warehouse An enterprise data warehouse constructed of multiple data marts and a request broker computer application. The data warehouse does not physically exist except through out the formation of the integrated data marts. California State University While this solves the problem of creating two sources for managing the same data, it comes with another inherent challenge. In the ITSM community it is considered a best practice to not only create relationships between CI records but also relationships from CI records to process records. For example the following relationships are critical to support ITSM:
  • The ability to associate CI records to each other to model systems and services as consumed by the business.
  • The ability to associate Incident, Problem, Change and Release records to CIs throughout their lifecycle
  • The ability to associate specific SLAs and business rules to CI records
When the CI is not instantiated and is only a virtual view on distributed data sources these relationships become severely restricted if not impossible. Troy
