Non-trivial functional dependencies in databases are relationships between attributes in a table where the determination of one attribute uniquely determines another attribute, and this relationship cannot be inferred from any subset of the attributes. In other words, non-trivial functional dependencies are important constraints that help maintain data integrity and prevent anomalies in the database. These dependencies are essential for database normalization and are used to ensure that the data is organized efficiently and accurately. **
