Useful applications for constant components could be (this is what you
can have in C++):

record  -- *not* Ada
  Name: constant String   := "James Bond";
  Id  : constant Positive := 007;  -- e.g employee number of a company
  other variable components
end record;

In Ada, you hide the components (private record), define a constructor
function providing the values for the constant items and provide only
read operations for them.
