I am working on a web api c# project using onion architecture and repository pattern and entity framework among other things. Doing some research I discovered a technique called side-loading
that basically helps client load additional information in a single rest api call.
Something like that is also mentioned in Json API http://jsonapi.org/examples/ as element "included"
Since this technique usually loads (but not necessarily) information store in different entities/repositories, I am not sure is this something that can or should be done in a single unit of work, or it has/should to be done through multiple database calls?
