Question:
Do we allow the user to change information about accounts, in case of an error? If we do allow the user to change account information, what attributes do we allow the user to change (account number, account name, balance forward, or opening date)?
Answer:
The account name can be changed. Since we're not going to want the system to have to go through all its information about transactions, and change account numbers for a large number of the transactions it knows about, we won't allow an account number to be changed.
For safety or sanity reasons (or both), it shouldn't be possible for the user to change either the balance forward, or the opening date.
