Repository, Service and Unit of Work

1

Should my controllers or services commit changes to database?
I currently have:

Core:

  • Invoice
  • Ticket

Application

Repositories:

  • IInvoiceRepository
  • ITicketRepository

Services:

  • IInvoiceService (gets invoices including their ticket)

Infrastructure

  • UnitOfWork (using DbContext and repositories as properties)
  • Repository implementation
  • Service implementation

Option 1:

InvoiceController.Delete:
var item = InvoiceService.GetAll()
InvoiceService.DeleteFull(item);
UoW.Commit();

Option 2:

InvoiceController.Delete:
var item = InvoiceService.GetAll()
InvoiceService.DeleteFull(item); // inside calls UoW.Commit();
