original business system object, the rest of the business system objects are
mapped to a
real object. Therefore, we call these objects shadow objects.
3.3.4 ROOT, BUSC, and LOBC objects
The only ROOT object in IBM Tivoli Business Systems Manager is the initial
object from which all objects descend. The ROOT object has an ID of 0001. In
the database, the ROOT object has two objects under it: the Business System
Container (BUSC) object and the LOB Container (LOBC). There is only one
instance each for BUSC and LOBC classes.
The BUSC object precedes all the objects in the All resource view, which
sometimes is called the physical tree. The LOBC object precedes all the
business systems objects, sometimes called the logical tree.
3.3.5 Object hierarchy
IBM Tivoli Business Systems Manager has two types of object hierarchy:
containment and inheritance. The containment hierarchy enforces what object
can be a descendant of an object, while the inheritance hierarchy provides the
inheritance feature of the object-oriented programming.

Figure 3-2 on page 86 shows a sample of the containment hierarchy.
