Service Types?

I'm looking for some common vocabulary to describe the various nomenclatures found in service operations. Here is what I've been using:

Pass-All Service – This is a service that passes the verb and noun into a generic service entry point. An example would be: “do( Add, Employee, EmployeeInfo)” , or do("insert into Employee ...")

Verb-Only Service – This is a service that states the kind of action that will be requested in the operation name, but passes in the nouns. An example is “Add(Employee, EmployeeInfo)”

Verb-Noun Service – This is a type of service that states both the action and the nouns (the target of the actions) in the operation name. An example would be AddEmployee( EmployeeInfo ).

Is there already terminology for these different interface styles? If so, please send me a note.
