asp.net mvc - Best practises for a Web Api -

-

i have movies table basic information , reviews table revies movies.

in app want show list name , avg score of movie. best practise?

do store avg field in movies table , use api/movies?

do have api return movies including reviews reviews , calculating in app (i guess not).

or necessary calcs on server , return view model needed?

have calcs done on server/database. assuming have back-end db store sql server, write query, stored procedure, or view calc on demand. don't need calculate on client (this slow , cause need transfer data) , don't need store average anywhere.
