 * Cayenne By Example - https://github.com/mrg/cbe
 *
 * This example builds upon BasicInserts3.
 *
 * It inserts many Person objects into the database within a single
 * commit/transaction.  A Role is added in order to illustrate mapping
 * Java enumerations to database values. Cayenne uses the RoleType
 * enumeration to handle the translation values (look at the Java Type
 * in Cayenne Modeler).
