/**
 * Defines strategies for fetching data from the database.
 * The <code>EAGER</code> strategy is a requirement on the persistence 
 * provider runtime that data must be eagerly fetched. The 
 * <code>LAZY</code> strategy is a hint to the persistence provider 
 * runtime that data should be fetched lazily when it is 
 * first accessed. The implementation is permitted to eagerly 
 * fetch data for which the <code>LAZY</code> strategy hint has been 
 * specified. 
 *
 * <pre>
 *   Example:
 *   &#064;Basic(fetch=LAZY)
 *   protected String getName() { return name; }
 * </pre>

 * @see Basic
 * @see ElementCollection
 * @see ManyToMany
 * @see OneToMany
 * @see ManyToOne
 * @see OneToOne
