What is data vault?

Data Vault is a hybrid data modeling system that provides an efficient and comprehensive solution for businesses' data needs through advanced techniques. It overcomes the limitations of 3NF and offers consistent, scalable, flexible, and adaptable designs suitable for modern enterprises. The core elements of a data vault include Hubs, Links, and Satellites. A Data Vault-based data warehouse consists of four layers: Staging Layer, Raw Data Vault, Business Data Vault, and Information Layer. Traditional data modeling approaches have several issues, such as time and effort, requirement of skilled workforce, non-adaptive approach, complicated code, lack of new data relationships, history management, and challenging data trails. However, the Data Vault schema addresses these shortcomings by offering adaptability, flexibility, less complexity, raw data availability, accommodation of change, data lineage and audit, speed, ease of access & automate, and advantage in the cloud.
