## Introduction
**Developer Information**  
- Chinese Name: 耿明赫  
- ID: 2023902045  
- English Name: Daniel  

## Project Overview
A C++ based banking system that implements customer management, account handling, transaction processing, and report generation.

## Features

### Account Management
- Automatic account creation (Savings + Checking for each customer)
- Unique account ID format: `62[type]-[branch]-[part1]-[part2]`
- Account types:
  - **Savings Account**: Transfer to own Checking only
  - **Checking Account**: Full operations

### Transaction Processing
- ✔️ Deposits (Checking only)
- ✔️ Withdrawals (Checking only)
- ✔️ Transfers:
  - Savings → Own Checking
  - Checking → Any account
- Complete transaction records

## System Architecture

### Core Classes
```cpp
class Account {};          // Base account
class SavingsAccount {};   // Savings account
class CheckingAccount {};  // Checking account
class Customer {};         // Customer data
class Bank {};             // Main system
class Transaction {};      // Transaction records
```
### Main Components
1. **Account Management**
   - Savings and Checking accounts
   - Transaction processing (deposit/withdraw/transfer)
   - Real-time balance tracking

2. **Customer Management**
   - Each customer has exactly 1 savings and 1 checking account
   - Customer name serves as unique identifier

3. **Transaction System**
   - Complete audit trail
   - Multiple report generation options
   - Automatic unique ID generation


## System Recommendation
A modular banking system with customer account management and transaction processing capabilities. The system follows object-oriented principles with clear separation of concerns between accounts, customers, transactions, and bank operations.

## Core Components

### 1. Account Management
- **Account Types**: Savings and Checking accounts with distinct behaviors
- **Transaction Processing**: Deposit, withdrawal, and transfer operations
- **Balance Tracking**: Real-time balance updates with validation

### 2. Customer Management
- **Account Ownership**: Each customer owns exactly one savings and one checking account
- **Profile Management**: Customer name serves as unique identifier

### 3. Transaction System
- **Complete Audit Trail**: All financial operations are recorded
- **Reporting**: Multiple report generation options (account, customer, global)
- **ID Generation**: Automatic unique ID generation for all transactions
