Data Vault 2.0 (DV2) is a system of business intelligence that includes: modeling, methodology, architecture, and implementation best practices. The benefits of Data Vault The components, also known as the pillars of DV2 are identified as follows: DV2 Modeling (changes to the model for performance and scalability) DV2 Methodology (following Scrum and agile best practices) DV2 Architecture (including NoSQL systems and Big Data systems) DV2 Implementation (pattern-based, automation, generation Capability Maturity Model Integration [CMMI] level 5) There are many special aspects of Data Vault , including the modeling style for the enterprise data warehouse. The methodology takes commonsense lessons from software development best practices such as CMMI, Six Sigma, total quality management (TQM), Lean initiatives, and cycle-time reduction and applies these notions for repeatability, consistency, automation, and error reduction. Each of these components plays a key role in th
