The Data Vault Handbook - Concepts and Applications

“ The Raw Data Vault stores data in its original raw format [...] crucial for auditing, traceability, and compliance.”

Raw Data Vault stores data in its original raw format, ensuring that no data is lost over time. This approach is crucial for auditing, traceability, and compliance, as it allows organizations to maintain a complete record of their data, with every change and update preserved in its his- torical context. Moreover, the Raw Data Vault’s architec- ture is highly scalable and flexible. By de- coupling the business logic from the data storage, it allows for easier integration of

new data sources and the ability to adapt to changing business requirements without significant reengineering. This flexibility makes the Raw Data Vault an ideal choice for organizations dealing with complex data environments or changing data structures. 2.2.2. BUSINESS VAULT The Business Vault serves as an intermediary layer between the Raw Data Vault and the Information Delivery layer. Situated within the Enterprise Data Warehouse (EDW) layer, the Business Vault is designed to bridge the gap be- tween raw, unmodified data stored in the Raw Data Vault and the end-user structures required for reporting and analysis. Unlike the Raw Data Vault, where data is stored in its original, unaltered form, the Business Vault allows for the application of soft (business) rules (Section 1.3.1) that modify the data, including its granularity, to better align with business needs.
