Bank Management Case Study

Problem Statement

XYZ Bank aims to automate the core functionalities of one of its branches. The project focuses on automating the following features:

1. Over the Counter Activities
2. Account Lifecycle Management
3. Interest Calculation
4. End-of-Day Reports for Daily Transactions

The bank supports multiple account types, each with specific requirements and functionalities:

• Savings Account: Requires an average minimum balance of ₹10,000.
• Salary Account: Similar to a savings account but requires at least one transaction within two months to remain active.
• Current Account: Offers overdraft facilities without specific balance requirements.
• Loan Account: Tracks loan repayment with an initial negative balance (loan amount) and interest calculated accordingly.

Requirements

1. Java JDK (Version SE-22)
2. Eclipse IDE (used as the development environment).
3. Basic understanding of OOP concepts in Java.

Approach

The project uses an object-oriented programming (OOP) approach to implement various account types and banking operations. It involves encapsulating different functionalities, such as account management, transactions, and reporting, in separate classes and modules.

Key functionalities include:

• Account creation, search, freezing, and unfreezing.
• Deposits, withdrawals, and balance checks.
• End-of-day (EOD) reporting for accounts created and transactions performed.
• Admin panel for managing all activities.

Technologies Used

• Java: Core language for implementing the system.
• Eclipse IDE: Development environment.
• Date and Time APIs: Used for handling account lifecycles and reporting.

Project Structure

The project follows a modular structure for better maintainability and scalability. Below is an overview:
