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:
There is a class Schema object for each class in the Active Directory database. For each object attribute in the database, there is an attributeSchema object.
PartitionsActive Directory objects are stored in the Directory Information Tree (DIT) which is broken into the following partitions:
The DIT holds a subset of Active Directory information and stores enough information to start and run the Active Directory service

An active directory schema allows the user to perform a detailed search for an individual, place or other piece of information. A well designed schema represents software that gives the user access to information within an organization. The structure becomes more detailed as the schema becomes detailed.
