企业库房管理软件挑战与有效解决方案

// 库存实体类定义
public class InventoryItem
{
    public int Id { get; set; }
    public string SKU { get; set; }
    public string Name { get; set; }
    public int Quantity { get; set; }
    public string Location { get; set; }
    public DateTime LastUpdated { get; set; }

// 库存管理服务
