- Quote: A data attribute describes the value found in each field in a table. Every field or column in a database table represents a single attribute of that table. (An attribute is what the data in that field represents, while the value is the actual data that a specific field contains.
- Quote: An attribute is a piece of information that needs to be known about the objects in a class. Each object might a have different value for an attribute. E.g. one dog is named Fido, the other is named Bowser.
- Quote: An attribute is an abstraction belonging to or characteristic of an entity.
- Quote: Attributes are part of a class declaration in UML. Objects are associated with attribute values describing properties of the object. An attribute has a name and a type specifying the domain of attribute values.
