Contact Details
Each Name can have multiple Contact Detail information such as:
Addresses
Telephone Numbers
Email Addresses
Skype Names
Each such contact detail can be Valid (if it is still used and applicable) or invalid if it is no longer used or applicable. So when someone changes address for instance you do not edit or over write their old address, you simply mark it invalid and add a new valid address. This way you are able to keep a history of old contact details for each Name.
