Hi Friends, I am Anshul Tiwari and welcome to our youtube channel ITkFunde.

About this video
In this video, we will understand what is a Data Vault and difference between 3NF
VS
Dimensional Model
VS
Data Vault.

Data Vault 2.0 is a data modeling technique that takes a hybrid approach towards designing a data warehouse by integrating good things of a 3NF (3rd Normal Form) and a Dimensional model. Data Vault is highly flexible, scalable and auditable which is required to build an agile data warehouse.

The pace at which business processes are evolving today, companies need a data warehouse that can easily absorb these changes while maintaining the data consistency. Data Vault with the help its 3 main components HUBS, LINKS and SATELLITES
provide a data model that can easily absorb these changes into an enterprise data warehouse.

3 components of Data Vault

1) Hubs Business keys which can be uniquely identified
2) Links Relationship defined between 2 hubs
3) Satellite Descriptor attached to a Hub which provides the business context

Data Vault offers an exciting option to be explored while designing an agile data warehouse. While you will still need dimensional models and data marts for Business Intelligence reporting. Data Vault can easily act as a middleman between source systems (3NF) and Data marts (Dimensional) as an enterprise data store or enterprise data warehouse.
