getaddressesbyaccount vs getaccountaddress

[philsong]

I found there are 2 functions: getaddressesbyaccount, getaccountaddress,
for me, I call getaccountaddress then get one account name's bitcoin address, and then call getaddressesbyaccount(account) to get the address in next time, but when I change the address book name of that address, then getaddressesbyaccount(original name) return empty, so why design these 2 function? what's their design purpose? If I need a account to map in my own system, which one should I use?

Accounts and labels use the same storage, so using both together is basically incompatible. Accounts will be removed in the future, so best to do this external to Bitcoin Core.

thanks luke, is there any timeline to remove Accounts? We are using account system as our own account system, please indict, thanks a lot.

btw, any suggestion for current good bitcoin open source account system?

The issue for tracking the removal of the account system would be #3816. Note that there doesn't seem to be any active work in this direction: there is no real replacement, the account system keeps on existing in a state of semi-unmaintained limbo.
