It is solely used by the hotel staff. The application is to be developed as a Console-based application (non-Graphical UI). Data should be stored in flat file format, either in text or binary. No database application (eg MySQL, MS Access, etc) is to be used. Also need to design the UML class diagram and sequence diagram.
