the data model
The data model
  • An example of a very basic model is how we can tell what kind of object ('Class') a particular 'Thing' is
  • The boxes are entity data types defined in the data model
  • Next to an identifier they have (almost) no attributes.
  • 'classification' is a relationship with two attributes:
    • 'classified' that refers to the thing that is classified
    • 'classifier' that refers to the classifying class
