About the Training:
This course is focused towards the fundamentals of Data Vault Data Modeling and this course will help you to clear interviews, to understand Data Vault Data Modeling fundamentals to step into Data Lake Environment.
A data vault is a data modeling design pattern used to build a data warehouse for enterprise-scale analytics. The data vault has three types of entities: hubs, links, and satellites. Hubs represent core business concepts, links represent relationships between hubs, and satellites store information about hubs and relationships between them. The data vault is a data model that is well-suited to organizations that are adopting the lakehouse. Data Modeling and Data Engineering skills combination are FULL STACK now. Data Engineers are asked to get adapted to the Data Modeling Environment.
