Gorm provides a way to define relationships between database tables using the _______ function.

Gorm provides a way to define relationships between database tables using the Assoc function. This function establishes associations between models, allowing you to specify the type of relationship (such as one-to-one, one-to-many, or many-to-many) and the foreign key constraints. By using Assoc, you can define how different models are related to each other in the database schema, enabling you to efficiently query related data and perform operations across associated records. This feature simplifies the process of managing relationships in Gorm applications and ensures data integrity by automatically handling foreign key constraints based on the defined associations.
