# 🏦 Bank Management System (Python + MySQL)
## 📖 Project Overview
This project is a **Bank Management System** built with **Python (for logic)** and **MySQL (for data storage)**.
It simulates real-world banking operations, enabling users to perform **account management and transaction handling** through a command-line interface.
The system is designed with **data integrity, usability, and persistence** in mind, making it a great foundation for understanding **database-driven applications**.
---
## ✨ Key Features
- **Account Creation** → Auto-generates unique 8-digit account numbers.
- **Transaction Handling** → Deposit and withdraw funds securely with balance validation.
- **Balance Enquiry** → Retrieve real-time balance for any account.
- **Customer Information** → Display account holder details with one query.
- **Account Closure** → Securely delete accounts with confirmation.
- **Database Integration** → Persistent data storage in MySQL.
---
## 🗂️ Database Design
The project uses a **normalized database schema** to ensure clarity and data consistency:
1. **`account_table`** – Stores personal and static account details.
2. **`amount_table`** – Stores financial data and is updated after each transaction.
This separation ensures **data modularity**, making it easier to track customer details and balances independently.
---
## ⚙️ Tech Stack
- **Programming Language:** Python 3.x
- **Database:** MySQL
- **Connector:** `mysql-connector-python`
Install requirements:
```bash
pip install mysql-connector-python
```
---
## 📸 Preview
---
## ▶️ How to Run
1. Import the SQL schema into MySQL:
```sql
SOURCE bank_management.sql;
```
2. Update credentials inside the Python script:
```python
conn = mysql.connector.connect(
host="localhost",
user="root",
password="YOUR_PASSWORD",
database="BANK_MANAGEMENT"
)
```
3. Run the program:
```bash
python bank_management.py
```
---
## 🔎 Findings & Insights
- **Data Validation** – Implemented error handling for invalid accounts and insufficient balances.
- **Scalability** – Separated tables for accounts and balances, making the system extensible for features like transaction history.
- **Efficiency** – Used direct SQL queries for CRUD operations, ensuring fast execution.
- **Reliability** – Added confirmation before critical actions (like account closure).
---
## 🚀 Challenges & Solutions
- **Challenge:** Handling duplicate account numbers.
**Solution:** Used `MAX(AccNo) + 1` logic to always generate unique IDs.
- **Challenge:** Ensuring consistent balance updates across deposits/withdrawals.
**Solution:** Transactions are committed only after successful SQL execution.
- **Challenge:** Preventing accidental data loss.
**Solution:** Account closure requires explicit user confirmation.
---
## 📈 Outcomes & Impact
- Simplified banking operations in a **digital format**.
- Provided a **learning foundation** for database-driven applications.
- Enhanced understanding of **Python-MySQL integration**.
- Built a base that can be extended into **web apps or GUIs**.
---
## 🌟 Future Improvements
- Add **user authentication & roles (Admin/Customer)**.
- Maintain **transaction history logs** for transparency.
- Build a **GUI (Tkinter/Flask/Django)** for better usability.
- Deploy on **cloud with remote database access**.
