高效化客户退货管理系统搭建 6 步曲：需求调研到上线运营全流程

// 退货实体类示例
public class ReturnRequest
{
    public int Id { get; set; }
    public string OrderNumber { get; set; }
    public DateTime RequestDate { get; set; }
    public ReturnStatus Status { get; set; }
    public string Reason { get; set; }
    public decimal RefundAmount { get; set; }
    
    // 导航属性
    public virtual ICollection ReturnItems { get; set; }
}

// 使用Entity Framework Core Code First模式
public class ReturnManagementContext : DbContext
{
    public DbSet ReturnRequests { get; set; }
    public DbSet ReturnItems { get; set; }
    
    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        // 配置实体关系和约束
        modelBuilder.Entity()
            .HasMany(r => r.ReturnItems)
            .WithOne(i => i.ReturnRequest)
            .HasForeignKey(i => i.ReturnRequestId);
    }
}

// 退货数据分析示例
class ReturnAnalytics {
  constructor() {
    this.returnData = [];
    this.chartOptions = {
      responsive: true,
      maintainAspectRatio: false
    };
  }
  
  // 分析退货原因分布
  analyzeReturnReasons() {
    const reasonCounts = {};
    this.returnData.forEach(request => {
      const reason = request.reason;
      reasonCounts[reason] = (reasonCounts[reason] || 0) + 1;
    });
    
    return this.formatAnalyticsData(reasonCounts);
  }
  
  // 生成月度退货趋势
  generateMonthlyTrend() {
    // 实现趋势分析逻辑
    const monthlyData = this.groupByMonth(this.returnData);
    return this.formatTrendData(monthlyData);
  }
  
  // 其他分析方法...
}
