Attributes in DBMS
Attributes are properties or characteristics of an entity. Attributes are used to describe the entity. The attribute is nothing but a piece of data that gives more information about the entity. Attributes are used to distinguish one entity from the other entity. Attributes help to categorize the entity and the entity can be easily retrieved and manipulate the entity. Attributes can help the database to be more structural and hierarchical. An entity with no attribute is of no use in the database.
