 * <b>Purpose</b>: Verify that declaring aggregate classes read-only has no effect if the source

 * <p>
 * <b>Responsibilities</b>:
 * <ul>
 * <li> Declare an aggregate class to be read-only.
 * <li> Make changes to the aggregate object.
 * <li> Write the source to the database and check that the changes were written to the database.
