Data type combining other data types with tuple? Syntax needed - Haskell

just a quick question as I'm not sure how to symatically go about this:

I've made a test to show you what I mean; I have

type Teacher    = String
type Assitant   = String
data Student    = String Int

The data they will contain will be: Teacher's name
Assistant's name
Student's name, age

--

I want to make another data called 'Classroom' but I'm not sure how I can contain all these types within the 'Classroom' data? So far I have:

data Classroom = Classroom Teacher Assistant [Student]

i.e. "Mrs. Cloud" "Terrence" [("Amy, 19), ("Paul", 20), ("Scott", 20)]

Cany anyone help me to change my Classroom data to allow the entry above? Many thanks, Mike

Your Classroom datatype is correct. But you need Student datatype either to have a constructor (as Classroom): data Student = Student String Int or to be a tuple synonym: type Student = (String, Int). The latter one matches to your example (just don't forget constructor of Classroom).
