What are the benefits of using foreign keys?
An example of an AI chatbot conversation about the advantages of foreign keys in databases.
What are the benefits of using foreign keys in a database?
Foreign keys help maintain data integrity by ensuring that relationships between tables are valid.
Can you explain how they enforce referential integrity?
Sure! Foreign keys ensure that a value in one table must match a value in another, preventing orphaned records.
What happens if I try to delete a record that has a foreign key relationship?
If you try to delete a record that is referenced by a foreign key, the database will prevent the deletion unless you handle it with cascading options.
Are there any performance implications of using foreign keys?
Yes, while foreign keys can slow down write operations due to additional checks, they improve data consistency and reliability.
