Data Vault is a data modeling methodology designed to provide long-term historical storage of data coming from multiple operational systems.
It focuses on capturing raw data from multiple operational systems while maintaining historical accuracy and adaptability. Unlike traditional approaches like Inmon or Kimball, Data Vault is a hybrid approach. It prioritizes flexibility by separating business keys, relationships and descriptive attributes into three core structures: Hubs, Links, and Satellites.
Hubs: Store unique business keys representing core business concepts to provide consistency across different systems.
Links: Capture associations between business keys, defining relationships and transactions.
Satellites: Store descriptive attributes and historical changes for data versioning and auditing.
