Data Graph Data Structures

In Data 360, a data graph is built within a data space and must have one primary data model object (DMO). You select a DMO in the data space to use as the foundation for the data graph. The foundation DMO is the primary DMO. You can also add data from DMOs that are related to the primary DMO, which are called related objects, and from related calculated insights. You can include calculated insights and streaming insights in a data graph if they’re based on a DMO that’s also included in the data graph.

A primary DMO can belong to any category except Engagement, with the Profile category being the most common. Related object DMOs can belong to the Profile, Other, or Engagement category. You select fields from the primary DMO and its related objects to include in the data graph.

When you create the data graph, the selected objects and fields are transformed from their original hierarchical relationships into a single, flattened, read-only data graph record. The data graph record contains metadata, such as the data space and data graph names. It also includes data from the primary DMO and the related objects as a queryable JSON blob.

Note New real-time data graphs don’t support N:1 relationships between DMOs. If you attempt to add a DMO that creates an N:1 relationship, the system prevents the selection. Existing real-time data graphs that already include N:1 relationships continue to run. However, changes made to the parent DMO in an N:1 relationship aren’t immediately reflected in the real-time data graph.

Example: How a Data Graph Is Constructed

This data graph has three DMOs. The primary DMO is Unified Individual. The Unified Link Individual DMO is a related object and a child of the Unified Individual DMO. The Individual DMO, which is a child of the Unified Link Individual DMO, is also selected as a related object. Each DMO has one or more fields selected. Taken together, the selected fields from these DMOs define the data graph’s JSON schema.
