Hibernate @ManyToMany Unidirectional

The Many-to-Many relationship can be best described by example.

The example we’re going to use is that of the relationship between an Author and a Book.

Authors publish Books, and Books have Authors. Any one Author can publish many Books, and any one Book can be published by many Authors, so this is why it is a many to many relationship.

Other examples of the many to many relationship are Students to Courses and Employees to Projects.

In this SQL tutorial episode/post we’re going to learn how to enforce our SQL relationships that we’ve already learned about. We’re going to be tackling the one-to-one and many-to-many relationships and we’re going to learn how to write the code to enforce these relationships in our database.

As outlined in the podcast, we are going to be focusing on the many-to-many relationship with the author and bookexample. Remember that one author can publish many books, and one book can be written by many authors. This indicates a many-to-many relationship and I’m going to show you how to enforce that relationship in your database...

In this post we will be expanding on the topic of database relationships and touch on two that are less common but just as useful.

Many-to-Many Relationship

The many-to-many database relationship is used when you are in the situation where the rows in the first table can map to multiple rows in the second table… and those rows in the second table can also map to multiple (different) rows in the first table.

One-to-One Relationship

A One-to-One relationship means that you have two tables that have a relationship, but that relationship only exists in such a way that any given row from Table A can have at most one matching row in Table B.
