The logical structure of active directory include forest, domains, tree, OUs and global catalogs.
Domain : a group of computer and other resources that are part of a windows server2003 network and share a common directory database.
Global catalog : Global catalog used to catch information about all object in a forest , the global catalog enables users and applications to find object in an active directory domain tree if the user or application knows one or more attributes of the target object.
Tree : Tree as is collection of Active directory Domain, that means the trust relationship can be used by all other domain in the forest as a means to access the domain.
Organization Unit - Organization Unit is a Active directory container into which object can be grouped for per mission management.
Forest : Active directory forest as due to represents the external boundary of the directory service.
These are two types of active directory forest :-
I) Single Forest
2) Multiple forest
root directory
It's Root Directory
the schema can be termed either conceptual or logical or physical. But mostly speaking, the term schema is used to refer to a logical structure.

Logical definition, according to or agreeing with the principles of logic, a geometry ought to refrain from such a course, in order to give to its structure the largest possible logical unity.
A directory is a logical grouping of files. By maintaining several directories the file manager can permit the same file name to be used in separate directories to refer to independent copies of the same file or completely different files. The contents of a directory - a list of file names and their associated information - are stored in a special file called a directory file which is assigned a file name which distinguishes it from non-directory files. By allowing directory file names to appear alongside non-directory file names in a directory, the file manager is able to link separate directories hierarchically as shown in figure 1. The directory at the top of the structure is given the special name, ROOT because the hierarchical structure resembles an upside-down tree. The directories below the root directory are known as subdirectories. by earnie

The physical component of Active directory contain all the physical subnet present in your network like domain controllers and replication between domain controllers.The logical structure of active directory include forest, domains, tree, OUs and global catalogs.Domain : a group of computer and other resources that are part of a windows server2003 network and share a common directory database.Global catalog : Global catalog used to catch information about all object in a forest , the global catalog enables users and applications to find object in an active directory domain tree if the user or application knows one or more attributes of the target object.Tree : Tree as is collection of Active directory Domain, that means the trust relationship can be used by all other domain in the forest as a means to access the domain.Organization Unit - Organization Unit is a Active directory container into which object can be grouped for per mission management.Forest : Active directory forest as due to represents the external boundary of the directory service.These are two types of active directory forest :-I) Single Forest2) Multiple forest
A logical database is the structure of data. It is the different pieces of information and the relationships between them.
overall logical structure of data
well of course one is logical and the other is physical. but one involves the brain while the other has to do with your body or movement
