Im sharing my learning from the Data Engineering Bootcamp, where we are learning about Data Engeering. Today we are learning about Dimensional modelling - Idempotency and SCDs.

I would like to extend my gratitude to Zach Wilson, the founder of DataExpert.io, for his invaluable guidance and the comprehensive Data Engineering Bootcamp. Connect with Zach Wilson on LinkedIn.

Thank you, Zach, for this amazing intense bootcamp on Data engineering!

Day-1: Dimensional Modelling (Theory)

What is a Dimension?​

Dimension are attributes of an entity ( example: user's name, age etc)

• Dimensions may be IDENTIFY an entity, which would be a unique identifier for the entity (example: user_id, device_id etc)
• Dimensions may be DESCRIPTIVE which would be the attributes of the entity (example: user's name,age etc) but wont be unique.
