The textbooks talks about the relationships between user forms and reports and their underlying database structure.
There are well-known structures used in forms and reports that translate into well-known patterns that appear regularly in an ERD (entity relationship diagram) database model. Describe one of these data modeling patterns, along with an example of when it would be used. Do not use the examples given in the textbook. Have you seen any of these well-known patterns in forms or reports you have encountered at work or on the Internet? Give an example and explain what it lets you infer about the underlying structure of the database behind it.
