I have a site like SO, WordPress, etc, where you make a post and u can have (optional) tags against it.
What is a common database schema to handle this? I’m assuming it’s a many<->many structure, with three tables.
Anyone have any ideas?

A three table many to many structure should be fine.
Eg.
Posts, PostsToTags(post_id,tag_id), TagsThe key is indexing. Make sure you PostsToTags table is indexed both ways (
post_id,tag_idandtag_id,post_id) also if read performance is ultra critical you could introduce an indexed view (which could give you post_name, tag_name)You will of course need indexes on Posts and Tags as well.
