![Overview:
A new bank wants to make a simple application to keep track of all accounts and transactions.
In this TMA, it is required to help the bank manager implement the required application.
Requirements:
After a quick meeting with the bank manager, you got the following information:
It is required to store all bank accounts in one collection and all the transactions happened
in another collection.
Each account has a unique account number, a holder and balance. There is a specific prefix
(common for all accounts) that should be added to the holder's civil id to create the unique
account number. In addition, it is not allowed for a holder to have more than one account.
Furthermore, only three transactions are allowed on any account: deposit, withdrawal and
transfer money to another account.
Each holder has a unique civil ID (national id), a name and other attributes (add at least 2
attributes from your choice).
For each transaction, it is required to store the account(s) affected, amount of money, date,
and if they are successful. There are 3 types of transactions: deposit, withdrawal and
transfer.
Moreover, you have been informed that the following operations happen frequently:
Creating a new account
Deposit money into a specified account
Withdrawal money from a specified account
Transfer money between two specified accounts
Printing details of the transaction where the maximum amount of money has been
transferred between 2 accounts
Saving all accounts and transactions into a text file.
For accounts, they should be sorted in ascending order (according to the civil id)
Analysis:
There are common attributes and methods between the three types of transactions. What
is the best choice for designing and writing their codes? Explain your answer.
Draw a simple class diagram showing only relationships between the classes.
Implementation:
After analysing the given requirements, implement the required application:
with Object Oriented Programming style
following the rules of good programming style (e.g. adding comments, etc.)
using only the material covered in M251 (and its prerequisites)](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F647ce735-784e-457f-b4b6-f60d09b8edfa%2F77cb83ad-1b62-4cd5-8b43-abc43fc9d3e1%2Fjxo1rxm_processed.jpeg&w=3840&q=75)
