package org.hibernate.boot.model.naming;

Pluggable strategy for applying implicit naming rules when an
explicit name is not given.

NOTE: the method names here mostly favor the JPA naming (aka, secondary table rather than join)

Methods fall into 2 main categories:

    

        Table naming

            
 Entity primary table - determinePrimaryTableName. Used when the primary table for an entity is not explicitly named in the metadata. See Table for details. 
            
 Join table - determineJoinTableName. See JoinTable for details. Join table covers basically any entity association whether in the form of a collection of entities (one-to-many, many-to-many) or a singular entity association (many-to-one, and occasionally one-to-one). 
            
 Collection table - determineCollectionTableName - Collection table refers to any non-entity collection (basic, component/embeddable, any). See CollectionTable for details. 
            

                Notice that secondary tables are not mentioned, since they must always be explicitly named
            
        
    
    

        Column naming
