Objects defined by a unique identity that persists over time, rather than their attributes. A User or an Order is an Entity. Even if a user changes their name or address, they are still the same user.
As they explored the project's domain model, John's eyes lit up. "Rachel, have you noticed how our current implementation doesn't align with the Ubiquitous Language principle?" Rachel nodded, and together they rethought their approach.

Pillar 1: Strategic Design (The Big Picture) A User or an Order is an Entity
Before exploring its digital life, it's crucial to understand the impact of the work itself. First published in 2003 by Addison-Wesley, Eric Evans' "Domain-Driven Design: Tackling Complexity in the Heart of Software" is the undisputed foundational text of DDD. Because of its distinctive blue cover, it is known throughout the industry as the "Blue Book."
