Data Record Attribute

A Data Record Attribute is a 2-tuple composed of a data attribute value and a metadata record that represents a single item property of a data record.

• AKA: Record Attribute, Tuple Attribute, Data Characteristic.
• Context:
  • It can range from being, depending on whether it has a data attribute value, from being a Populated Data Record Attribute to being an Unpopulated Data Record Attribute.
  • It can be associated to a Data Record Set Attribute.
  • It can range, depending on the attribute type, from being binary, categorical, ordinal, to being numerical.
  • It can be:
    • an Interval Attribute.
    • a Ratio Attribute.
    • a Text Data Attribute.
    • a Reference Data Attribute, such as a Concept Reference Data Attribute.
  • It can be:
    • created by a Create Operation.
    • updated by an Update Operation, e.g. 1) the value of the weight attribute is updated to [math]\displaystyle{ x }[/math], 2) the name of the weight attribute is now y.
    • deleted by an Delete Operation, e.g. the weight attribute is deleted.
  • It can be implemented as a column in a Database Table.
  • It can contain information that describes an Item at a certain point in time (the Item's state). I.e. They are things we need to know about an entity.
  • It can be associated to a Data Quality Metric.
  • It can be a Learning Record Attribute, such as a Target Attribute.
  • …
• Example(s):
  • (Name.First, “Michael”), from a Person Record such as: [Name.First="Michael", Name.Last="Jackson"].
  • (Publication.Title, "The Oxford Handbook of Computational Linguistics), from a Citation Record.
  • (Synonym,"...”), from a WordNet Record.
  • …
• Counter-Example(s):
  • a Program Data Object, such as a Program Variable or a Data Structure.
  • a Data Record Attribute Value.
  • a Concept Property.

• 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.
• Quote: Characteristics or objects closely associated with or that belong to people or things.
