[Zope] How/Where to store user specific data?

[Thomas Guettler]

How (Where) can I store user specific data?

I am developing a product in python (Multible Choice Test) and want to
store some data for every user (Results of the tests).

I see two ways: 
 Add data to the user object in acl_users 
  or
 Store data in a hash with the user-id as key

What do you think?
