The default data model

The default data model diagrams show the BMC Discovery default shipping model including the main sections of the model. The diagrams should be useful if you are building searches and using the model to understand it. The aim of the diagrams are to be a quick reference to complement the detail recorded in this Node Lifecycle information and the taxonomy.

It does not represent the entire BMC Discovery data model and therefore does not show all the nodes, attributes or relationships.

Further details of the data model can be found in the BMC Discovery taxonomy. To view the taxonomy on the BMC Discovery UI, from the main menu, click the Administration iconThe Administration page displays. From the Model section, click View Taxonomy. A link to the current, full-size version of the diagrams below is also available in the online documentation.

Taxonomy limitation

The relationships displayed in the taxonomy are not exhaustive. That is, all possible relationships are not displayed in the taxonomy.
For example, the following containment relationships are valid:

  • Group:Container:Containment:ContainedItem:SoftwareInstance
  • Group:Container:Containment:ContainedItem:Host

The following diagrams show the BMC Discovery Default Data Model with its different nodes, attributes and relationships between different parts of BMC Discovery. It is split across the following diagrams:

  • Main Diagram—contains all the core entities used in the modeling and discovery of hosts.
  • Network and Printer Diagram—contains entities used in the modeling and discovery of network devices and printers.
  • Mainframe Diagram—contains entities used in the modeling and discovery of mainframe computers.
  • Storage and Load Balancers—contains entities used in the modeling and discovery of storage entities and load balancers.

It is important to note that the model itself is not in separate sections, the separate diagrams exist in order to more clearly convey information.

    The DDD node kinds and the provenance are now missing from the data model compared to the previous versions.

    Is this intentional ? This is a very useful information when traversing from DDD to inferred nodes using the query language.

    Hi Arnaud. We removed that information in a previous release as we felt it more important to have a usable inferred model diagram. The DDD to inferred node traversals are still available to see in the system taxonomy Admin > Model > View Taxonomy.

    Thanks, Duncan.

    It would be great if you add colours to the graphs, now is not very easy to follow the flow.

    Is there a textual or CSV version of this model? I would like to add it to a modelling tool (archi) and be able to go through the relationships, specifically the cloud Class and attributes

      Hi Jacques.

      Thanks for your query. While it's not possible to extract a text or CSV version of the model, you have an option to download the base taxonomy in an XML format. When you are viewing Administration > Taxonomy, from the Files tab, click the 00taxonomy.xml link. For details, see the topic, Viewing the system taxonomy. (But note that the relationships displayed in the taxonomy are not exhaustive.)

      Let me know if this helps.
