In a database schema testing scenario, you encounter a situation where a foreign key constraint is not enforced, allowing incorrect data relationships. What potential risks can this pose to the application, and how should you handle it?
- Data Duplication; Remove duplicate entries from the database
- Data Inconsistency; Enforce foreign key constraints to maintain data integrity
- Data Loss; Perform regular backups to mitigate risks of incorrect data relationships
- Data Redundancy; Implement unique constraints to ensure data uniqueness
The absence of enforced foreign key constraints can lead to data inconsistency, where incorrect relationships between tables exist. This poses risks such as invalid data references and integrity issues. Enforcing foreign key constraints is crucial to maintain data integrity and ensure accurate relationships between tables in the database.
