- The key objective of the Control Tower Report Migration CTRM initiative is to re-engineer the current Control Tower Reporting CTR environment to that of a dimensional design environment with an analytics platform specifically designed for Business Intelligence BI reporting and decision-support analytics. Re-engineering current CTR data structures into dimensional Data Marts will provide a robust and reliable reporting environment that delivers the information management needs to make business decisions. Additionally, the intent is to transform CTRM into a new process structure with the appropriate rigor and controls that would sustain data quality and alleviate any user confidence, as well as, policy compliance issues.
