## 系统架构设计
### 三层架构：
1. **核心引擎层**：
- C++：高性能金融计算、复杂模型处理
- Python：数据分析、监管规则处理、可视化
2. **服务层**：
- RESTful API接口
- 消息队列系统
- 数据存储与管理
3. **应用层**：
- Web管理平台
- 移动端APP（iOS/Android）
- 桌面客户端（Windows/Mac）

## 核心模块实现
### 1. 企业估值引擎 (C++)
```cpp

// 计算终值
double terminalValue = freeCashFlows.back() * (1 + terminalGrowthRate) /

}
// 可比公司分析 (Comps)

}
};
int main() {
try {
// DCF 示例
std::vector
double dcfValue = ValuationModel::dcfValuation(cashFlows, 0.02, 0.1, 5);
std::cout << "DCF Valuation: $" << dcfValue << std::endl;
