博客的数据库设计

Question

I'm looking for the best way to design database for simple blog. My idea is:

• Posts table - contains id, content, etc.,
• Categories - contains category id, name, link-name (simple name used for example in routes),
• Tags - tag id, tag name, link-name,
• CategoriesMap - contains post id and category id, post may have a few categories,
• TagMap - as above.

Is it good solution? I use Symfony3 with Doctrine and MySQL.

Answer 1

In addition to the tables above, I recommend you add the following tables:

1. staff: a table for staff which may include fields like: id, name, role (Author, Editor, etc), email, password, photo etc. Then add the staff id on the Posts table.
2. visitor: a table of visitors is not a bad idea either. It have have fields like visitor id, name(null=YES), email(null=YES), subscription(YES/NO/NULL), ip_address(null=YES), favorite_category(null=YES) etc.
3. comment: In addition, you may want to have a comment table where you have fields like: id, message, visitor_id, post_id etc.

Answer 2

A user table should be there to track the post authors and to implement a login/registration system. The same table can be used to securely manage the blog posts.

Also, comment system is an integral part of a blogging system. You can either have a table to store comments or integrate an external commenting system.
