Post relationships allow you to create connections between your custom post types. Using them means you can eliminate data duplication, meaning each element only needs to be edited once.
Once you have created your post relationships you, of course, will need to add content to your custom post types which will be useful for the user. One of the easiest ways to do this is by using repeatable field groups. Repeatable field groups let you add a set of fields to a custom post type as many times as you need without having to recreate them one by one.
