Data Modelling: Navigating the Data Seas with a Data Vault Compass
summary
Claim: Data Vault yields scalability, auditability and flexibility for messy lakes. Example: a boutique shows a false 10x revenue spike caused by per‑meter carpet rows, exposing lack of keys and modeling. At scale one customer handles 1 billion rows a day across 500 tables and runs the pipeline with less than two people to maintain. Implementation uses automation: Data Vault Builder plus cloud warehouses like Snowflake to generate models, pipelines and versioned metadata that actually run.
