Bank Management System Python MySQL project for class 12 computer science students with source code and output to download. This is one of the core projects that almost all computer science students need to prepare. Bank Management System Python MySQL project helps them to understand the different techniques of Database but also helps them to understand the business rules, software needs to follow.

We tried our best to keep the Banking System Project as simple as we can. Only two Tables has been used throughout the project.

Database of Banking System is maintained in MySQL tables- Customer and Transaction.

The structure of the Customer Table is as follows

mysql> desc customer;
+-----------+--------------+------+-----+---------+----------------+
| Field     | Type         | Null | Key | Default | Extra          |
+-----------+--------------+------+-----+---------+----------------+
| acno      | int(11)      | NO   | PRI | NULL    | auto_increment |
| name      | char(30)     | YES  |     | NULL    |                |
| address   | varchar(100) | YES  |     | NULL    |                |
| phone     | varchar(15)  | YES  |     | NULL    |                |
| email     | varchar(80)  | YES  |     | NULL    |                |
| aadhar_no | varchar(20)  | YES  |     | NULL    |                |
| acc_type  | varchar(20)  | YES  |     | NULL    |                |
| status    | char(15)     | YES  |     | NULL    |                |
| balance   | float(15,2)  | YES  |     | NULL    |                |
+-----------+--------------+------+-----+---------+----------------+
9 rows in set (0.02 sec)

Note:

• Account number is defined as a primary key as well as this will auto_increment.
• Account number is also serving as a foreign key in Transaction Table

Structure of the Transaction Table

mysql> desc transaction;
+--------+----------+------+-----+---------+----------------+
| Field  | Type     | Null | Key | Default | Extra          |
+--------+----------+------+-----+---------+----------------+
| tid    | int(11)  | NO   | PRI | NULL    | auto_increment |
| dot    | date     | YES  |     | NULL    |                |
| amount | int(10)  | YES  |     | NULL    |                |
| type   | char(20) | YES  |     | NULL    |                |
| acno   | int(10)  | YES  |     | NULL    |                |
+--------+----------+------+-----+---------+----------------+
5 rows in set (0.01 sec)

Initial Data in these two tables are

mysql> select * from customer;

| acno | name           | address           | phone       | email                  | aadhar_no      | acc_type | status | balance  |

MySQL.connector is used to make a connection between Python and MySQL. Learn more about how to connect MySQL with Python. MySQL connector is avilable from Python.org site.

The whole code is divided into user-defined Python functions. These functions have been called from the main menu to generate the initial menu system. The source code of the Banking Management System project is as follows

Limitations of Bank Management Project

Though this project seems to be complete but there are some limitations of this project. Few of them are as follows

• The system is directly accessible by anyone. A login system can be maintained to reduce misuse.
• Reports can be made more user friendly
• More report options can be there.
• Searching options can be increased.
• GUI version is highly recommended.
• Dealing with only the core functionality of the bank.

Conclusion

Besides all the features and shortcomings, this is one of the best Bank Management System project designed for the student. Here students will learn modular programming, connectivity with Python, and how to implement business rules in any software.
