Have you used annotations to describe database modification requirements?

Yes, notations that help formalize and structure information are often used to describe database modification requirements. For example, ER diagram notation (Entity-Relationship) is widely used for modeling data structure and relationships between tables. UML class diagrams can also be used to describe objects and their attributes, which is useful in database design.

Example: An ER diagram showing the relationships between the "Users" and "Orders" tables helps clearly define the requirements for new fields or relationships during database modification.
