What are Entities and Relationships? |
|
Answer» ENTITY: An entity can be a real-world object, EITHER tangible or intangible, that can be easily identifiable. For example, in a college DATABASE, students, professors, WORKERS, departments, and PROJECTS can be referred to as entities. Each entity has some associated properties that provide it an identity. Relationships: Relations or links between entities that have something to do with each other. For example - The employee's table in a company's database can be associated with the salary table in the same database. |
