I just downloaded the assignment document. The document only requires me to implement searching,showing and updating functionalities at the GUI side, means the user can only search the records, select one and update it (make a booking). However, in the interface that I have to implement, there are 3 methods: delete(), create() and lock(). How could a user use those methods through GUI? Do I have to provide those functionalities (which are not required in the document) on GUI? If not, how can the assessor run those methods?
Thanks for every reply. I appreciate your generous help.
