I am getting frustrated in my attempt to use default names since I don't know 
what they are and cannot find a reference.  Table and column names were changed 
from underscores to camel-case so no problem there: what you see is what you 
get. My relations, however, are another story. 

What is the default join column from a book to its category? I think it's 
CATEGORY_ID. Where can I see in black-and-white (or suitable color:) what the 
default naming rules are? Since I have control of the schema I want to leverage 
defaults as much as is practical. 


  | 
  | class Category 
  | {
  |    ...
  |    @Id @GeneratedValue(strategy = GenerationType.AUTO) public long 
getId()...
  | 
  |    @OneToMany(mappedBy = "category") public List<Books> getBooks()...
  |    ...
  | }
  | 
  | class Book
  | {
  |    ...
  |    @Id @GeneratedValue(strategy = GenerationType.AUTO) public long 
getId()...
  | 
  |    @ManyToOne public Category getCategory()...
  |    ...
  | }
  | 
  |
