All Implemented Interfaces:

java.io.Serializable
```
@Entity
public class Book
extends java.lang.Object
implements java.io.Serializable
```
An immutable persistent entity represents a Book.
The mutable properties of the book such as number of items in stock etc. are factored out in a separate Inventory instance.
The state of inventory is mutable, but the relation to inventory is immutable.
Identity: Application-defined identity.
Mapping: One-to-One bi-directional, immutable mapping to Inventory. Many-to-Many bi-directional mapping to Author.
Version: No.
