Fields related to Reactions&term definitions in Forums table

[Sswaroop]

Hi All,

I'm trying to find metrics related to Reactions - How many reactions for each post/comment & Top 10 posts/comments with max number of reactions of a particular type.

I'm trying to understand how I can connect relations to posts/comments in the Mysql database. I could only find Core_Reactions which has the list of all the reactions. How can I tie this to posts/comments?

Also, in the Forums_Forums table what does the fields skin_id and parent_id represents?
