Ontology modeling

This lesson turns raw data into a semantic model by defining entities, relationships, and identity rules inside the ontology layer.

Review the ontology list

Open Modeling under the Ontology group in the left sidebar. Review the ontologies that already exist and check how they are mapped to collections.

Enter the Ontology Builder

Before opening a new ontology, select the target collection first. Then click Open builder to start designing the model inside the right workspace boundary.

Work in the Ontology Builder

The Ontology Builder opens as a visual graph canvas. You place entity and relationship nodes directly on the canvas and connect them into the structure you need.

Create entities and relationships

Use the left panel and the top controls to define the entities and relationships that make up the backbone of the ontology, then render them on the canvas.

Fill in entity metadata

For each entity, enter the name, display alias, description, and tags.

Define identity keys and properties

To preserve uniqueness and prevent duplicate loads, configure identity keys. You can also define a composite key when multiple fields together identify one business object. Then enter the property types and details for each entity field.

What you should be able to do after this lesson

• Explain why collection mapping must be chosen before entering the Ontology Builder
• Define entities, relationships, and identity keys, including composite keys
• Understand the difference between the integrity-focused storage path and the analytics-focused storage path

Next lesson

In the next lesson, you build a pipeline, load data, and connect the result to a dashboard.
