Single table inheritance
========================

There is no native inheritance support in most relational databases so it should be implemented manually if needed.
One of approaches to the problem is called [single table inheritance](http://martinfowler.com/eaaCatalog/singleTableInheritance.html),
described well by Martin Fowler.

According to the pattern in the entity table we add an additional column called `type` that determines which class will be instantiated from a row of data.

Let's implement simple car types inheritance with the following class structure:

```
Car
|- SportCar
|- HeavyCar
```

Get ready
