1. What is active directory schema

 

All databases have a schema which is a formal definition (set of rules) which govern the database structure and types of objects and attributes which can be contained in the database. The schema contains a list of all classes and attributes in the forest.
The schema keeps track of:

• Classes
• Class attributes
• Class relationships such as subclasses (Child classes that inherit attributes from the super class) and super classes (Parent classes).
• Object relationships such as what objects are contained by other objects or what objects contain other objects.

Active Directory schema contains formal definitions of every object class that can be created in an Active Directory forest. The schema also contains formal definitions of every attribute that can exist in an Active Directory object. This section provides the reference for each schema object and provides a brief explanation of the attributes, classes, and other objects that comprise the Active Directory schema.
