[Haskell-cafe] Getting started

[aditya siram]

Firstly, do you mean "recordSale sales anArtist anAlbum" ?

First off consider a datatype to model albums - something like:
type Name = String
type Artist = String
type Sold = Int
data Album = Album Name Sold

And consider storing then in a hash [1] where the artist name is the
key and [Album] is the value.
