Database Entities
An entity is a thing or object of importance about which data must be captured. Not all “things” are entities, only those things about which you need to capture information.

If something is a candidate for being an entity and it has no attributes or relationships, it is not really an entity. A database entity appears in a data model as a box with a title that is the name of the entity.
