Class name is the target, then methods have target_high, target_low, represents the advanced target interface management and low-level management interface,
But at the same time and there's a class name targetBLL, corresponding method is target_delete, target_update, represents the target information to delete the business logic and target information update business logic,
I said in the following sequence diagrams show that right? Or delete, update should switch to high and low? See figure, thank you for your answer
