用于代码点火器的通知系统的数据库表结构

Question

I have to create a notification system in Codeigniter .

In this notification two types of user, One is Buyer and Second is Seller.

Buyer Buy or Review any Seller's product/order then this notification should be sent to seller.

Same is seller review to any buyer then this notification should be sent to that Buyer.

All Rating/Review and order system is working. But I have to built a notification for this.

I am little confuse on notification table structure. Can any mysql, sql or sql-server expert help me on this?

NOTE:- I am using below table structure for this. But I don't think this is good.

notification_id
user_id
module
action_type
added_by
read
read_date

Module is where it was performed at, and action_type is what happened (comment, deletion, added, etc). Read is if it's already been viewed, and read_date is when it was viewed.

Answer 1

It should be like this:

column_name

notification_id
product_id -> for which product buyer has notified
action_type -> 'comment','like'
added_by -> who gave the notification
read -> 0 or 1
read_date -> datetime
