asp.net mvc entity framework 数据库 练习（一）

本文启发的思路来源于asp.net mvc 6 的entity framework，微软MSDN中的官方项目contoso university 虚构的数据库

针对项目中的实际需求，考虑使用的数据结构包括：生产线员工，生产线设备，产品型号，工艺数据等信息。

    public class UserInfo
    {
        public string UserID { get; set; }
        public string UserName { get; set; }
        public int UserAge { get; set; }
        public string UserSkill { get; set; }
        public string UserJob { get; set; }
        public string UserRole { get; set; }
        public string UserStatus { get; set; }
        public string UserFingerPrint { get; set; }
        public string UserTeamNum { get; set; }
        public DateTime UserTime { get; set; }
        public string UserPassword { get; set; }

        public virtual ICollection<DeviceInfo> DeviceInfoes { get; set; }
        public virtual ICollection<ProductInfo> ProductInfoes { get; set; }
    }

    //Device 
    public class DeviceInfo
    {
        public int DeviceID { get; set; }
        public string DeviceName { get; set; }
        public DateTime? DeviceTimeBought { get; set; }
        public DateTime? DeviceTimeUseAll { get; set; }
        public DateTime? DeviceTimeUserAfterMaintain { get; set; }
        public DateTime? DeviceTimeUseThisTime { get; set; }
        public DateTime? DeviceMaintainTime { get; set; }
        public string DevieceUser { get; set; }
        public string DeviceBelonging { get; set; }
        public string DeviceRunCycyle { get; set; }
        public string DevicepartNum { get; set; }
        public int? ProductID { get; set; }
        public string UserID { get; set; }

        public virtual UserInfo UserInfo { get; set; }
        public virtual ProductInfo ProductInfo { get; set; }

    }

    public class ProductInfo
    {
        public int ProductID { get; set; }
        public string DeviceID { get; set; }
        public string UserID { get; set; }
        public int ProductpipeLineNum { get; set; }
        public int ProductOrderNum { get; set; }
        public string ProductMark { get; set; }
        public float? ProductParameter { get; set; }
        public float? ProductDifference { get; set; }
        public float? ProductRunOut { get; set; }
        public string ProductRivetPart { get; set; }
        public string ProductRivet2Part { get; set; }
        public string ProductRubPart { get; set; }
        public string ProductHubPart { get; set; }
        public string ProductSuckPart { get; set; }
        public string ProductPadPart { get; set; }
        public string ProductTeamNum { get; set; }
        public string ProductStatus { get; set; }
        public DateTime? ProductStartTime { get; set; }
        public DateTime? ProductFinishedTime { get; set; }
        public bool ProductResult { get; set; }

        public virtual UserInfo UserInfo { get; set; }
        public virtual DeviceInfo DeviceInfo { get; set; }


    }

    //ParameterData
    public class ParameterDate
    {

        public DateTime? PDPickTime { get; set; }
        public string PDRunout { get; set; }
        public string PDDifference { get; set; }
        public string PDPressure { get; set; }
        public string PDStatus { get; set; }
        public string PDCountID { get; set; }
        public string ProductID { get; set; }

        public string DeviceID { get; set; }
        public string UserID { get; set; }

        public virtual UserInfo UserInfo { get; set; }
        public virtual ProductInfo ProductInfo { get; set; }
        public virtual DeviceInfo DeviceInfo { get; set; }
    }

通过设计数据库将数据关联起来，实现crud操作，下一节内容继续按照文章的思路继续。
