A class from which one or more other classes inherit information.

The type of object that represents a directory entry or record.

The category to which the object classes are assigned:

Structural: Object classes that can have instances in the directory. Structural classes are used to create directory objects or entries.
Abstract: Template object classes that are used only to derive new structural classes. You cannot instantiate abstract classes in the directory.
Auxiliary: A list of attributes that you can append to the definition of a Structural or Abstract class. You cannot instantiate an Auxiliary class in the directory.
Deduced: The Informatica object class type resulting from the union of attributes of all the object classes of the selected DN.

A single-valued property of an instance of an object class that contains the distinguished name of either the class of which the object is an instance or one of its superclasses. When an object is created, the system sets its objectCategory property to the value specified by the defaultObjectCategory property of its object class.
