In this course, you'll explore how nested collections within an outer entity can be mapped using JPA. You'll implement mappings for collections of primitive types, embeddable objects, and collections of entities. You'll examine how JPA and Hibernate handle list, set, and map collections. Next, you'll relate how specific operations such as entity persistence, update, and removal can be cascaded from parent entities to child entities and illustrate how inheritance relationships in your code can be mapped to database tables. Once you're done with this course, you'll be able to use nested collections within your entities and also map inheritance relationships in your code to meaningful representations using tables.
