以下是一个CRM系统开发的技术架构概述和核心模块设计指南，供技术开发参考：
一、技术架构设计
1. 分层架构：
– 前端：React/Vue + TypeScript
– 网关层：Nginx反向代理
– 业务层：Spring Boot/Django REST Framework
– 数据层：MySQL/PostgreSQL + Redis
– 基础设施：Docker + Kubernetes
2. 微服务模块划分：
– 用户认证服务
– 客户管理服务
– 销售管道服务
– 数据分析服务
– 消息通知服务
二、核心数据库设计（MySQL示例）
“`sql
CREATE TABLE customers (
id INT AUTO_INCREMENT PRIMARY KEY,
name VARCHAR(100) NOT NULL,
email VARCHAR(100) UNIQUE,
phone VARCHAR(20),
company VARCHAR(100),
created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);
CREATE TABLE contacts (
id INT AUTO_INCREMENT PRIMARY KEY,
customer_id INT,
first_name VARCHAR(50),
last_name VARCHAR(50),
position VARCHAR(50),
FOREIGN KEY (customer_id) REFERENCES customers(id)
);
CREATE TABLE sales_opportunities (
id INT AUTO_INCREMENT PRIMARY KEY,
title VARCHAR(200),
value DECIMAL(12,2),
stage ENUM(‘prospect’, ‘qualification’, ‘proposal’, ‘negotiation’, ‘closed’),
probability TINYINT,
owner_id INT,
created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);
“`
三、核心功能模块示例（Python Django）
1. 客户模型扩展：
“`python
class Customer(models.Model):
TIER_CHOICES = [
(‘A’, ‘VIP’),
(‘B’, ‘Standard’),
(‘C’, ‘Basic’)
]
name = models.CharField(max_length=100)
email = models.EmailField(unique=True)
tier = models.CharField(max_length=1, choices=TIER_CHOICES)
created_by = models.ForeignKey(User, on_delete=models.CASCADE)
tags = TaggableManager()
class Interaction(models.Model):
customer = models.ForeignKey(Customer, on_delete=models.CASCADE)
type = models.CharField(max_length=20) call/email/meeting
notes = models.TextField()
timestamp = models.DateTimeField(auto_now_add=True)
“`
2. REST API示例（DRF）：
“`python
class CustomerViewSet(viewsets.ModelViewSet):
queryset = Customer.objects.all()
serializer_class = CustomerSerializer
permission_classes = [IsAuthenticated, CRMReadPermission]
@action(detail=True, methods=[‘post’])
def add_note(self, request, pk=None):
customer = self.get_object()
Note.objects.create(
customer=customer,
content=request.data[‘content’],
author=request.user
)
return Response({‘status’: ‘note added’})
“`
四、关键功能实现
1. 销售管道状态机：
“`javascript
class SalesPipeline {
constructor() {
this.states = {
prospect: [‘qualification’, ‘lost’],
qualification: [‘proposal’, ‘disqualified’],
proposal: [‘negotiation’, ‘rejected’],
negotiation: [‘closed_won’, ‘closed_lost’],
closed_won: [],
closed_lost: []
};
}
transition(currentState, newState) {
if (this.states[currentState].includes(newState)) {
return newState;
}
throw new Error(‘Invalid state transition’);
}
}
“`
五、安全设计
1. RBAC权限控制：
“`java
@PreAuthorize(“hasRole(‘SALES_MANAGER’) || hasAccessToCustomer(customerId)”)
public Customer updateCustomer(Long customerId, CustomerDTO dto) {
// 业务逻辑
}
“`
2. 审计日志实现：
“`python
class AuditLogMiddleware:
def process_response(self, request, response):
if request.user.is_authenticated:
AuditLog.objects.create(
user=request.user,
path=request.path,
method=request.method,
status_code=response.status_code,
timestamp=timezone.now()
)
return response
“`
六、扩展性设计
1. 插件架构：
“`typescript
interface CRMPlugin {
name: string;
initialize(config: PluginConfig): void;
registerRoutes(router: Router): void;
}
class EmailIntegrationPlugin implements CRMPlugin {
initialize(config) {
// 初始化邮件服务
}
}
“`
七、部署方案
1. Docker Compose示例：
“`yaml
services:
web:
image: crm-web:latest
ports:
– “8000:8000”
depends_on:
– db
db:
image: postgres:14
environment:
POSTGRES_PASSWORD: example
“`
建议结合具体业务需求选择技术栈，参考开源项目如Odoo、SuiteCRM进行二次开发。完整实现需要包括：RBAC权限系统、客户生命周期管理、销售自动化、数据分析仪表盘、第三方集成接口等模块。开发时应特别注意数据隐私保护和合规性要求（GDPR等）。
