This article will delve into the core principles of Data Vault 2.0, the training process, its benefits, and how it can be applied in real-world scenarios.

Understanding Data Vault 2.0



Data Vault 2.0 is an evolution of the original Data Vault methodology, which was developed by Dan Linstedt in the late 1990s. The primary aim of Data Vault is to create a scalable, flexible, and auditable data warehouse architecture that can accommodate changes in business requirements and data sources over time.

Core Components of Data Vault 2.0



Data Vault 2.0 introduces several key concepts and components that are essential for creating a robust data warehouse:

1. Hubs: Hubs serve as the central points in a Data Vault model, representing unique business entities. They contain a list of unique keys and their associated metadata, such as load dates and source systems.

2. Links: Links are used to establish relationships between Hubs. They capture the associations between business entities and can accommodate many-to-many relationships.

3. Satellites: Satellites store descriptive attributes related to Hubs and Links. They allow for historical tracking of data changes over time, enabling organizations to maintain an accurate history of their data.

4. Business Vault: This layer contains additional business logic and derived data that might be needed for reporting and analytics. It enhances the core Data Vault structure with calculated fields and aggregated information.

5. Raw Data Vault: This layer is focused on capturing raw data from source systems without business transformations, ensuring that the original data is preserved for future analysis.
