Create a database design ERD for a Hotel Business using Lucidchart or other software that confirms to crows foot notation.

The hotel software would need to support customers making reservations, checking in, checking out, billing and payment for the rooms they book. The model should include capability to track employees performing the front desk operations as well as staff cleaning rooms, performing bell hop services and valet parking including the billing for valet parking. Mock up your thoughts on business requirements for what these functions should be from your experience or research about the hotel industry.
