Why Data Vault?

Not to be confused with Oracle Database Vault (a commercial db security product), Data Vault Modeling is a specific data modeling technique for designing highly flexible, scalable, and adaptable data structures for enterprise data warehouse repositories. It has been in use globally for over 10 years now but is not widely known. The purpose of this presentation is to provide an overview of the features of a Data Vault modeled EDW that distinguish it from the more traditional third normal form (3NF) or dimensional (i.e., star schema) modeling approaches used in most shops today. Topics will include dealing with evolving data requirements in an EDW (i.e., model agility), partitioning of data elements based on rate of change (and how that affects load speed and storage requirements), and where it fits in a typical Oracle EDW architecture.
