Mark Correct if it solved your issue or hit Like and Helpful if you find my response worthy.

Let's say you are posting a question on community and community is your service now instance

First, I need to check that you not posting
any offensive materials. I can have a before rule to check that. According to
the rules setup by me, either allow or disallow the posting of the question
(Transaction).

Second, after you have passed the rules of
posting and posted the question successfully. Someone opens up your question
and likes your question. I need to award you points once the like is
successful. I can have a after business rule to set this up.

Third, you will need to get email trigger
when someone comments on your question. It does not need to be immediate. I can
have a async rule to trigger the email.

Finally, I need to update the number of views
of your question. I can have a display business rule to update the counter
related to your question ..

Another practical example is when showing record producer variables in record, and hiding the empty variables.

You can refer to article

Hide Empty Variables on a Standard Form - ServiceNow Guru

Quoting from article

the key to making this work is a 'display' business rule. The business rule runs before the display of any record in the table (tasks in this case) and queries the 'sc_item_option_mtom' and 'question_answer' tables to collect any variable names for empty variables. Then it passes this information in the 'g_scratchpad' object to the client to hide the variables on the form.
