What is difference between services which are categorized as Business Service > Application Service vs Application Service ?

[Ishan4]

So there are attributes on [cmdb_ci_service] table. 

1.) Service Classification

2.) Class

and for example two services: 

a.) service classification = Business Service; class = Application Service

b.) service classification = Application Service

How is Service (a.) different from service (b.) ?

Thanks for your reply, but I have a question.

There is button given on [cmdb_ci_service] to convert a Business Service to Application Seervice then it changes Service classification value from Business Service to Application Service . Although in docs it is mentioned while conversion class should have been changed, could explain it please.
