Question

Software design

Actually, what set of fields do they have and what to apply when?

Answer 1

Usually they are all combined into one, making CommentFeedbackReviewDiscussion
For example, the steam game store, leaving a comment on the game is at the same time feedback, review and makes it possible to include sub comments, which makes the discussion entity.
feedback - freelance exchange, a review about a client, a product, contains a rating
review - a review of a product, which describes the pros and cons, etc., contains a
comment rating - it has nothing to do with the higher ones, a stupid set of characters, words, questions, etc., which goes into a disk

. After the book is published, critics will write reviews for newspapers and websites, and anyone can make comments about it to their friends (or they could send their comments to you).

I came to the conclusion that there are certain cases that when to use, for example:
BlogPost - Comment
Video (YouTube) - combination of Comment + Review + Discussion, you can comment on the comment
Product or Service - Review
Client - Feedback (freelance)
TVSeries / TVShow - - combination of Comment + Review, but
TV Company - feedback, if he buys a video, then we do a Review for the product as described above

Review - Formal assessment usually done by professional (it usually also have a structure). Long, deep description.
Feedback - Giving opinion or assessment by someone (friend, customer etc) of how something or someone is doing XYZ.
Comment - raw, draft personal opinion, opened for discussion.

It is important to note that, for example, reddit has a tree structure. You can comment on a comment, comment, comment, etc.
Quora

A simple comparison is that a comment is a few words or sentences with the writers observations on a document or an event. A review is a longer, more formal write-up concerning a position paper, a theatrical/ cinema performance or someones work over a set period of time.

Answer 2

These entities have less in common than anything else. And it really depends on the subject area.
