Windows 2008 and Windows Server 2003 Active Directory uses a database set of rules called "Schema".
The Schema is defines as the formal definition of all object classes, and the attributes that make up those
object classes, that can be stored in the directory. As mentioned earlier, the Active Directory database
includes a default Schema, which defines many object classes, such as users, groups, computers, domains,
organizational units, and so on. These objects are also known as "Classes". The Active Directory Schema
can be dynamically extensible, meaning that you can modify the schema by defining new object types and
their attributes and by defining new attributes for existing objects. You can do this either with the Schema
Manager snap-in tool included with Windows 2008/2003 Server.
