Introduction to Data Vault Modeling
Abstract
This section covers the Data Vault 2.0 Model in brief. From a conceptual level, the Data Vault model is a hub and spoke based model, designed to focus its integration patterns around business keys. The concepts are derived from business context (or business ontologies), which are elements that make sense to the business from a master data perspective, such as customer, product, service, and so on. A Data Vault model is a detail-oriented, historical tracking, and uniquely linked set of normalized tables that support one or more functional areas of business. In Data Vault 2.0, the model entities are keyed by hashes, where in Data Vault 1.0 the model entities are keyed by sequences.
