Hi There,

I am seeking some advice regarding best practice on Appservices. Let say I have an Individual Entity and it has an Employment Entity. User can create an Individual entity and can later create an Employment entity for an existing Individual. So in my application layer, option one) i could create an IndividualAppservice to have a method for creating individual and a method for creating employment. or option two) i could create an IndividualAppservice for creating individual and create an employmentAppservice for creating employment for an existing individual. With option one, i will need to inject two repositories to the appservice, with** option two**, i will just inject one respective repository to each appservice.

My question is how best to construct appservice for parent and child relationship entity

  1. should i use one parent appserivce(option one) or split them into its own appservice(two)
  2. what is the optima number repository or domain manager to be injected

thanks

    Hi @lweng567

    If you want to call one app service from another in option two, we don't suggest using this approach becasue app services must be representing use cases of the end user applications.

    In your case, if these entities can be used separately, it is better to define two different app services. You can even define a domain service for these two entities and use it in both app services.
