I am doing the assignment of "Bodgitt and Scarper". I have some question about the information provided in the instruction.html file

According the requirement,for the owner field, " If this field is all blanks, the record is available for sale". Does that mean that if the record has been filled with some customer's id, other user could not book and overwrite it with new customer id? So even the user could book the record, but he still could not update it with new customer id since the field is already filt with some other customer id? If so, could the user release the record and remove the customer id? Or all records will be filt in short time.

Could anyone help me?

Thanks a lot. I am looking forward to hearing from you ASAP.

That's for you to decide.

I've decided that a customer ID can be overwritten by another or removed, but extra confirmation is required before the system does that.
