Hi Long,

Check your instructions. You probably have a line with the comment: "
Note that for this application, you should assume that customers and CSRs know their customer ids.".
In other words, in your client application, you will build something that allows the CSRs to type in the customer ID. You will then save that in the relevant field, which will indicate to all other clients that the record is booked.
