Relationships

The NCIM topology database models relationships between entities.

Connectivity data
Connectivity data defines how entities are connected in the network. It includes connections between different devices, and VLAN-related connections within the same device. Connectivity information is stored in the topologyLinks, networkPipe, and pipeComposition tables.
Containment data
Containment data defines logical and physical containment within your network. A containment model is generated at the end of the discovery process when the network topology is created. This model reflects the real-world topology of the network that is being modelled, in a physical, logical or business-oriented sense.
Dependencies
When one entity in a system cannot meaningfully function without another entity it is said to be dependent. Dependencies can be defined by the containment model. A container can be dependent upon the objects it contains.
Collection data
Collection data defines logical collections. Collections are defined in the collects table. Examples of logical collections defined within NCIM include MPLS VPNs, global VLANs, and subnets.
Hosted services
A hosted service is a service or application running on a specific device. For example, a device can host BGP or OSPF services. NCIM can also model the fact that a software application, is running on a workstation.
