How class diagram is important in UML?
Class diagrams are the most important kind of UML diagram and are vitally important in software development. Class diagrams are the best way to illustrate a system’s structure in a detailed way, showing its attributes, operations as well as its inter-relationships.
What UML diagram should I use?
There are a few UML diagrams that are used in most situations in software development or systems modeling, including IT infrastructure and business systems. The top three UML diagrams that you should get comfortable with include use case diagrams, class diagrams (if you are a programmer), and sequence diagrams.

Monthly reports are prepared by the system which may be viewed on request by the Hotel Manager. Produce a Use Case and Activity diagram for the hotel. You are mixing actors and systems.
