Description: Entity control is a design pattern that manages the lifecycle of an entity within a system. This pattern focuses on the creation, updating, and deletion of entities, ensuring data integrity and facilitating interaction with other parts of the system. By implementing entity control, the goal is to decouple business logic from data access logic, allowing for greater flexibility and scalability in application development. This pattern is particularly useful in systems where entities have a complex lifecycle and require detailed tracking of their states and transitions. Additionally, entity control can help simplify transaction management, ensuring that operations on entities are performed consistently and securely. In summary, entity control is essential for designing robust and maintainable systems, providing a clear structure for handling entities throughout their lifecycle.
