Method create is required in the data module interface. But I do not see anywhere I can call this method. Besides, if a client makes a reservation. Do we need to update the owner field or mark this item "deleted" as well as updating the owner field.
Hi Daniel - I think the forum's been around the block a few times about this debate. Search on 'create', 'delete', etc. to see what the suggestions are.
I'm not aware that many implement either function in the GUI. Some implement in the Data class to fulfill the "supplied" interface. Others implement both as no-op methods and document/justify in choices.txt. It's your call.
The instructions say this about booking a record"
"The id value (an 8 digit number) of the customer who has booked this. Note that for this application, you should assume that customers and CSRs know their customer ids. The system you are writing does not interact with these numbers, rather it simply records them. If this field is all blanks, the record is available for sale."
I wouldn't feel comfortable deleting this record. This might be a trivial example, but what if the hotels linked to this DB, or at least a replica of the DB? Searching for deleted records wouldn't be a very effective means of checking in a customer.
Moreover, there's no information in the schema that provides a context for the delete. For example, when was the record deleted? And by whom? Are you displaying deleted records to the CSRs? What about reserved rooms? That could also drive your choice of how to handle it.
