* This annotation is used to specify multiple secondary tables

*
* Example 1: Multiple secondary tables assuming primary key columns are named the same in all tables.

* @Entity
* @Table(name="EMPLOYEE")
* @SecondaryTables({

* @Entity
* @Table(name="EMPLOYEE")
* @SecondaryTables({
* @SecondaryTable(name="EMP_DETAIL",
