How do you make an entity relationship diagram for a hotel?

Answer

The first step in making an entity relationship diagram (ERD) is to make a list of all the parties or 'entities' involved. Once you do this, write down the relationships that each entity has to the others: drawing the ERD will be easy once you have this information. Finally, draw the different entities with enough space between them and connect them with lines based on their relationships.
