The Core Model provides classes and associations you can use to develop applications in which systems and their functions are represented as managed objects. These classes and associations embody the characteristics unique to all elements that comprise a system: physical and logical elements. Physical characteristics refer to the qualities of occupying space and conforming to the elementary laws of physics. Logical characteristics represent abstractions used to manage and coordinate aspects of the physical environment, such as system state or the capabilities of a system.
In the Core Model, logical elements can include the following.
Table A-1 Core Model Elements
Element Name |
Description |
Systems |
A grouping of other logical elements. Because systems are themselves logical elements, a system can be composed of other systems. |
Network Components |
Classes that provide a topological view of a network. |
Services and Access Points |
Provide a mechanism for organizing the structures that provide access to the capabilities of a system. |
Devices |
An abstraction or emulation of a hardware entity, that may or may not be realized in physical hardware. |
The following sections describe the classes and associations provided by the Core Model to emulate the qualities of systems.
