history over 'long periods' of time- unlike Query/400
which only reports on the 'current' content, and only
the current content, of database records. |
| Query/400
also will not track what changes have taken place against
a given record - such as a travel booking, or an order
no or a bank account no unless the customer's application

can also report on who made the change, using what program
(and they can see whether this is standard or otherwise)
when and what the record contained before and after.
This is totally different to Query/400. |
