Entities are something you can create data about. In this entity relationship diagram, the entities are broken down into customer, product, and invoice. Attributes are what go into an entity that are used to record the data. Name is an example of an attribute under the customer entity. All three of these entities share the relationship of being information needed to record the data that is stored in the records for a cabin rental company. They are all related as the attributes are all recorded on an invoice but are then broken down into three entities.
