/**
* 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:
* @Basic(fetch=LAZY)
* protected String getName() { return name; }
* </pre>
*
* @see Basic
* @see ElementCollection
* @see ManyToMany
* @see OneToMany
* @see ManyToOne
* @see OneToOne
