Comment Hierarchy Comments Section DataBase in SQL Server

Introduction

In this article, we will delve into the intricacies of creating a hierarchical comment section database for ASP.NET. The database design is an integral part of implementing an interactive and dynamic comment system, commonly found on social networking sites, forums, and blogs. The images below provide a visual representation of the proposed database structure.

In this article i'm going to explain about comment hierarchical comment section database designs as i shown in above images. So first we need to create database table's UserTable, ParentCommentTable and ChildCommentTable.

DataBase Table : UserTable

To kickstart our database design, we first create the UserTable to store user credentials. This table includes columns for Username and Password.

CREATE TABLE UserTable(
  Username varchar(25),
  Password varchar(25),
  Primary Key(Username))
 Go

 Insert into UserTable values('Paul','Paul1')
 Insert into UserTable values('Robert','Rober1')
 Insert into UserTable values('James','James1')
 Insert into UserTable values('Mary','Mary1')
 Insert into UserTable values('Albert','Albert1')

This table serves the purpose of user authentication, allowing users with valid credentials to post comments.

DataBase : ParentCommentTable

The ParentCommentTable is designed to store parent comments, each identified by a unique CommentID. It includes columns for Username, CommentMessage, and CommentDate.

CREATE TABLE ParentCommentTable(
 CommentID int identity(1,1),
 Username varchar(25),
 CommentMessage varchar(300),
 CommentDate date,
 Primary Key(CommentID),
 Foreign Key(Username) References UserTable(Username))

Parent comments are created when users directly post comments through the comment section on websites.

DataBase Table : ChildCommentTable

For replies to existing comments, we introduce the ChildCommentTable. Each reply is associated with a parent comment through the ParentCommentID.

CREATE TABLE ChildCommentTable(
 CommentID int identity(1,1),
 Username varchar(25),
 CommentMessage varchar(300),
 CommentDate date,
 ParentCommentID int,
 Primary Key(CommentID),
 Foreign Key(ParentCommentID) References ParentCommentTable(CommentID),
 Foreign Key(Username) References UserTable(Username)) 

Child comments represent replies to existing parent comments and are linked to them through the ParentCommentID.

Conclusion

This database design lays the foundation for a robust hierarchical comment section in ASP.NET. The UserTable ensures secure user authentication, while the ParentCommentTable and ChildCommentTable organize and store comments efficiently. This structured approach allows for the creation of dynamic and interactive comment sections on websites.
