Draw an ERD for the following requirements

There are many air conditioners in EMU. Each air conditioner has a unique inventory number. We have to store the model and make of each air conditioner. Each air conditioner is located in a room. Each room is identified by a unique roomid. We also store the capacity and type of the room. Each air conditioner is serviced twice a year. For each service, we need to store the date of the service and the name of the person who performed the service.
