In this scenario, we need to introduce a new table to maintain the many-to-many relationship between movies and cast members. A movie can have multiple people involved (such as actors, directors, writers), and a person can be involved in multiple movies in different roles. To model this relationship effectively, we can use a junction table that connects movies, persons, and roles.

cast table :

This table defines the different roles a person can have in a movie (e.g., Director, Actor, Writer).

person table :

This table stores the people involved in movies.

movie table :

This table stores information about the movies.

now the relationship table comes into the picture , that contains the relation ship between the movie , person and roles in a single view.

movie_cast_relationship_table :

This junction table defines the relationship between movies, persons, and their roles (cast).

This design provides a clear and normalized way to represent the many-to-many relationship between movies and people, with specific roles defined for each connection.
