In SilverStripe, application data will be represented by a [DataObject](api:SilverStripe\ORM\DataObject) class. A `DataObject` subclass defines the
data columns, relationships and properties of a particular data record. For example, [Member](api:SilverStripe\Security\Member) is a `DataObject` 
which stores information about a person, CMS user or mail subscriber.
