Final answer:
Cascade option defines the behavior of the database in a one-to-many mapping when performing an operation on the parent entity. Inverse option determines the direction of the relationship between the parent and child entities.
Step-by-step explanation:
In one-to-many mapping, the cascade option refers to the behavior of a database when a operation is performed on a parent entity that has a relationship with multiple child entities. The cascade option allows the operation to be automatically applied to the child entities as well.
On the other hand, the inverse option is used to define the direction of the relationship between the parent and child entities. When the inverse option is set to true, it means that the child entity is responsible for managing and updating the relationship.
For example, in a database representing students and courses, if a student is deleted and the cascade option is enabled, all the courses associated with that student will also be deleted. The inverse option, on the other hand, determines whether updating the relationship from the student side or the course side is required to establish the association.
