In Domain-Driven Design (DDD), the concept of an Entity is used to represent the key concepts of the business domain. An Entity is an object that has a unique identity and an associated set of attributes and behaviors. This post explores what an Entity is, why it’s important, and how it can be used to improve the design of software systems. By modeling the key concepts of the business domain as Entities, we can ensure that the system is closely aligned with the business domain and that it meets the needs of the business. Entities are a powerful tool for modeling the key concepts of the business domain in Domain-Driven Design. They help to create a clear separation between the business domain and the implementation of the system and ensure that the system is closely aligned with the business domain.
