A value type is a type which doesn't have existence of its own, but belongs to an entity, like an user and his address. Value types are always completely owned by their containing entity.
We will embed an Address class inside a User class. The simplest way to embed a value type in an entity class is to treat the member variables of the embedded class (e.g. Address), the same way as we treat the member variables of the embedding class (e.g. User) by adding more columns to the entity table one column each for the value type class members
