ATM system development log [3] [00 original]

Today, the withdrawal is completed :-)
The progress is as follows:

Withdrawal:
After entering the withdrawal, select the Account type (current account, regular account, and credit card account). After selecting the Account type, the maximum amount that the ATM can withdraw at a time-2000 yuan done
A user's account (the user may have multiple accounts) can withdraw up to 5000 yuan a day. Done
After you select "withdraw money", select a fixed amount (,) on the system interface, or enter the amount to withdraw the money done
If the withdrawal amount is greater than the balance, the system prompts that the balance is insufficient done.
If the amount obtained is greater than 2000 of the maximum amount that the ATM can withdraw at a time, a prompt is displayed, re-enter the withdrawal amount or select done
If the cumulative amount obtained in a day is greater than the cumulative amount withdrawn in a day (5000) of the Account, a prompt is displayed, and the withdrawal amount is re-entered or the card is selected
Credit card accounts can be used for overdraft withdrawal, with a overdraft amount of 2000 Yuan. Other accounts are not allowed to overdraft withdrawal done
After the withdrawal, the system prompts you to return the card or continue the done service.
Withdrawal from a regular account. If the regular account does not expire, a 10 yuan fee will be charged for one withdrawal transaction, and done will be deducted from the balance.
Withdrawal from a current account. For example, if the number of withdrawal transactions in the current month is no more than 5 times (<= 5), no transaction handling fee is required. If the number of withdrawal transactions exceeds 5 times, a withdrawal transaction is charged with a processing fee of 2 RMB, deduct from balance

The last item is to create a table in the database. Well, the preliminary design is not complete. It is really difficult to design!

You need to query the progress of the balance module as follows:

After selecting an account, go to the account balance query page and display the following information:
Show account information done

Show the actual balance done

Display the amount of money that can be withdrawn (5000 minus the amount of money that has been acquired on the current day) done

After that, the user can choose to return the card or continue to select the service done

In the "show Account Information" section, I have displayed the account ID and Account type. It should be enough :-)

Now we have the "query history transactions" and "transfer funds" functions to achieve this. Please come on!
