-**Description:** This application maps a Java `enum` via `AttributeConverter`. In other words, it maps the `enum` values `HORROR`, `ANTHOLOGY` and `HISTORY` to the integers `1`, `2` and `3` and viceversa. This allows us to set the column type as `SMALLINT` which is less space-consuming then `VARCHAR`.
