-## 功能模块
+## 2. 整体架构与技术栈
-1. **仪表板** - 数据概览和统计
-2. **项目管理** - 项目创建、查看、编辑
-3. **财务管理** - 预支申请、报销申请
-4. **报表中心** - 财务报表查看
 
-## 技术栈
+本系统采用前后端分离的现代化架构，通过 Docker 容器化部署以确保高可用性。
-- 前端：React + TypeScript + Ant Design + Vite
-- 后端：Node.js + Express
-- 数据库：PostgreSQL
 
-## 服务管理
+### 技术栈展示：
-```bash
+- **后端技术**：Node.js + Express
-# 查看服务状态
+- **前端技术**：React 18 + TypeScript + Ant Design 5 + Vite
-netstat -tlnp | grep -E ':3000|:3001'
+- **数据库**：PostgreSQL 15
+- **部署技术**：Docker / Docker Compose

+
+## 4. 核心业务功能
+
+- **项目管理**：支持项目的创建、进度跟踪、合同与里程碑管理。
+- **财务管理**：包括财务报销、预支款申请、付款申请与核销流程。
+- **采购与供应链**：商品管理、采购申请、订单管理与入库记录。
+- **伙伴管理**：集中管理供应商、分包商与客户信息。
+- **数据分析与仪表盘**：直观展示核心财务数据及项目状态。
+
+## 5. 实际应用场景示例
+
+- **跨国分公司财务管控**：海外分公司提交预支与报销申请，总部可在线审核，统一汇率转换及预算扣减。
+- **工程类项目核算**：将施工日志与项目付款节点绑定，确保按进度结算分包商款项。
+- **企业日常运营**：员工出差报销、办公采购，全流程数字化审批与记录。
+
+## 6. 帮助解决的核心问题
+
+- **财务数据孤岛**：项目信息与财务开销割裂，难以追踪真实成本。
+- **审批效率低下**：传统纸质或邮件审批慢、易遗漏。
+- **预算超支风险**：缺乏实时的数据监控及超支预警机制。
+
+## 7. 快速开始
+
+### 环境要求
+- Docker 及 Docker Compose
+- Node.js (如需本地独立运行)
+
+### 安装与运行步骤 (基于 Docker)
+
+本系统内置了 `docker-compose.full.yml` 文件及示例数据初始化脚本，可一键启动全套服务。
+
+1. **一键构建与启动**：
+   ```bash
+   docker-compose -f docker-compose.full.yml up -d --build
+   ```
+2. **检查服务状态**：
+   ```bash
+   docker-compose -f docker-compose.full.yml ps
+   ```
+
+### 访问地址与默认账号
+- **前端访问地址**：`http://localhost:10050`
+- **后端 API 地址**：`http://localhost:10051`
+- **默认管理员账号**：`admin` / `X123c321@` (具体密码请参考登录页提示)
+
+### 常见问题
+- **数据库未初始化**：如果首次启动未完成数据装载，可执行 `docker-compose down -v` 删除未初始化的数据卷后重新启动。
+- **端口冲突**：如果 `10050` 或 `10051` 端口已被占用，请修改 `docker-compose.full.yml` 中的端口映射。
