The Data Vault Handbook - Concepts and Applications

The Raw Vault, being purely focused on capturing hard facts without apply- ing any business logic, is an ideal candidate to remain centralized. It serves as a clean, shared foundation of data, which all domains can access with- out having to manage redundant staging processes. By centralizing the Raw Data Vault, we can leverage high levels of automation, ensuring that all raw data is available for various domains to build upon while preventing unnec- essary duplication of effort or data.

Once we move to the Business Vault and the Information Mart, decentraliza- tion becomes more advantageous. These layers apply business rules, which are best understood by the specific domains. By decentralizing at these lay- ers, we allow domain teams to take full ownership of their data products, applying their expertise to transform raw data into meaningful business insights. This approach also empowers the domains to work independent- ly, reducing bottlenecks typically found in centralized IT departments and accelerating the delivery of new data products.
