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.
