There are several _ that can be used in ERDs, such as:
Composite Pattern: This pattern allows entities to be grouped together into a single entity, forming a hierarchy. It is useful when dealing with complex relationships or when there is a need to represent parts of a whole.
Decorator Pattern: This pattern allows entities to be extended with additional attributes or behavior dynamically. It is useful when there is a need to add functionality to entities without modifying their existing structure.
_ Pattern: This pattern allows entities to be notified of changes in other entities. It is useful when there is a need to maintain consistent relationships between entities and update them accordingly.
By applying these design patterns, we can improve the flexibility, maintainability, and extensibility of our entity-relationship diagrams.
