维护视频文件的ViewCount数量

Question

我需要关于模式更改的帮助。我有一个存储视频的视频表，我想知道视频的实际ViewCount。

这里是我现在有视频表模式：

CREATE TABLE dbo.VideoFiles(
VideoId  int IDENTITY(1, 1) PRIMARY KEY, 
VideoTitle nvarchar(64) NOT NULL, 
VideoDescription nvarchar(2048), 
PublishDate date, 
Duration time, 
VideoUrl nvarchar(256), 
--ViewCount bigint, 
UpdateTime datetime default CURRENT_TIMESTAMP) 

我可以有一个ViewCount列，其将在每次启动的视频文件，它看起来像简单的方式增加了+1。但是，如何在视频视图中管理唯一性？

User1 view Video1 = Video1 Count =>1 
User2 view Video1 = Video1 Count =>2 
User1 view Video2 = Video2 Count =>1 
User1 view Video1 = Video1 Count =>2 (not increased as he already seen this video) 

感谢，

所需的结构可能看起来像这样

CREATE TABLE [dbo].[ViedeoViews](
    [VideoID] [int] NOT NULL, 
    [UserID] [int] NOT NULL, 
CONSTRAINT [PK_ViedeoViews] PRIMARY KEY CLUSTERED 
(
    [VideoID] ASC, 
    [UserID] ASC 
) ON [PRIMARY] 
) ON [PRIMARY] 

GO 

ALTER TABLE [dbo].[ViedeoViews] WITH CHECK ADD CONSTRAINT [FK_ViedeoViews_VideoFiles] FOREIGN KEY([VideoID]) 
REFERENCES [dbo].[VideoFiles] ([VideoId]) 
GO 

ALTER TABLE [dbo].[ViedeoViews] CHECK CONSTRAINT [FK_ViedeoViews_VideoFiles] 
GO 



Create View V_VideoFiles as 
Select dbo.VideoFiles.*,(Select COUNT(*) from ViedeoViews vv where vv.VideoID=VideoFiles.VideoID) as ViewCount 
from VideoFiles

创建一个表

UserId int/UniqueIdentifier 
VideoId Int 
TimeOfView Datetime 
SessionId int/UniqueIdentifier
