Two tables here - one for cars, and one for stats on engines in cars. Engines are shared across cars, so there are multiple cars for every EngineStat.

I'd like to use hibernate to make a single query on EngineStat and receive all cars with that engine as a field of the EngineStat class.

I believe this is a one-to-many relationship, but do please correct me if that is wrong. I would like to use Java annotations only - no .hbm.xml file.

```java
@javax.persistence.Entity
@javax.persistence.Table(name = "CAR", schema = "ftm")
class Car {
  @Id
  @Column(name = "car_id")
  long carId;

  @Column(name = "engine_id")
  long engineId;

  @Column(name = "model")
  ...... more stuff
}

@javax.persistence.Entity
@javax.persistence.Table(name = "ENGINE_STAT", schema = "ftm")
class EngineStat {
  @Id
  @Column(name = "engine_id")
  long engineId;

  @Column(name = "horse_power")
  ..... more stuff

  // <---- Some annotations here 
  Set<Car> cars;
}

```
