Please find my suggested db design below, tags: id, name types: id, name posts: id, name teachers: id, name books: id, name, type_id books_tags: id, book_id, tag_id All ids are auto increment & primary fields.
So if, the book with (id, name, type_id) = (6, 'Bookname', 2) has two tags with (id, name) = (11, 'Chemistry') & (23, 'Grade A'), then the entry in the books_tags(book_id, tag_id) table for this will be - (6, 11) & (6, 23) .
