> I propose the introduction of the following entities: AccommodationClass, AccommodationSpot,AccommodationMap. Their design is based on the book "The data model resource book". 
>  -  AccommodationClass could define classes for hotels, cars, planes etc. I have added one more field here parentAccClass, as I thought it could be valuable for building more complicated hierarchies.
>  -  AccommodationMap is used to say how many spaces a class has. I have extended it further with a field overbooked, which could store the overbooking data for each class. E.g if we have that field we might know how many rooms of class "deluxe" could be overbooked. The primary key of AccommodationMap in the book includes the "NrOfSpaces" field but I did not add it in the patch as I am not sure of its exact purpose.
>  - AccommodationSpot defines the specific seat,room etc of a given class. It is very powerful entity as it let us define the seat as a spot simply. This is very useful for planes and buses for example as we have the chance to define all the seats as spots and are not required to make them fas. I have modified the type of the field "accomNumber" to be of type short-varchar as plane seats for example are mixture of letters and numbers(The book models it of type numeric). The fk fields include the "nrOfSpaces" field in the book which I have not included in my patch.
