This should start by explaining what a OneToMany mapping is, and how it is represented in the database. Ideally a picture of the object/model/database schema. It should explain the three different types (using a join table (default), bi-directional using a mappedBy/target foreign key, unidirectional using a JoinColumn (and issues with this)).
