Question

I’m in the design phase of a small project.I’ve an activity class and resource class.
Each activity can have multiple resources, So my question is should I create a collection of resources like IList<resource> and add it to Activity class or should I create some service class whose purpose is to assign resources to each activity

Regards,
Ravi

Answer 1

You should create both.

In your domain model, the Activity class should contain ICollection.

In your Service / Business Logic class, you should have ability to add.remove Resources from Activity

Assigning single responsibility to classes helps keeping your code clean and maintainable.

Hope it helps.
