I am working on a Message Board kind of Application where I have the Master table Comments and Detail/History Table called CommentsHistory.

I need advice on how to deal with Comment Text, Status, ModifiedBy and ModifiedOn, If I keep all of them in CommentsHistory then I will need a view with FirstCommentHistoryID and LastCommentHistoryID for each comment to find the Original Comment and it was by who and what is the latest Comment,Status, By Who and Date/Time.

My current table structue is like
CREATE TABLE [dbo].[Comments] (
      [CommentID] [int] IDENTITY (1, 1) NOT NULL ,
      [SurveyItemID] [int] NOT NULL ,
      [Status] [smallint] NULL ,
      [Priority] [smallint] NULL ,
      [AssignedTo] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
      [InternalDiscussion] [smallint] NULL
) ON [PRIMARY]
GO


CREATE TABLE [dbo].[CommentHistory] (
      [CommentHistoryID] [int] IDENTITY (1, 1) NOT NULL ,
      [CommentID] [int] NOT NULL ,
      [ByWho] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL ,
      [OnDateTime] [datetime] NULL ,
      [Status] [int] NOT NULL ,
      [Comment] [varchar] (4000) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
      [Instruction] [varchar] (2000) COLLATE SQL_Latin1_General_CP1_CI_AS NULL
) ON [PRIMARY]
GO

Is having a view and joining back to History table to get the Original and Latest info about the comments a good approach?
