Which operation does account maintenance involve?

Account maintenance primarily involves the ongoing management and updating of user account data, which includes making nondollar changes such as updating contact information, changing passwords, or modifying user preferences. This operation is essential to ensure that the account information remains accurate, secure, and reflective of the user's current situation.

While major changes to financial data, such as changing account limits or interest rates, can be important, these are usually categorized as adjustments rather than routine maintenance. Similarly, adding funds to accounts and retrieving account history are specific transactions or actions rather than maintenance. Account maintenance focuses specifically on administrative changes related to the user account itself, making nondollar changes the correct focus.
