The document describes Centennium's Centennium Datawarehouse Methodology (CDM) which provides a standardized approach for building data warehouses. The CDM includes structured templates for modeling, generating, and managing data warehouses. It utilizes best practices like Data Vault and reference architectures. The CDM process involves knowledge transfer from Centennium to customers through training and coaching so customers can independently maintain their data warehouses using the CDM.
