You can use the Entity types option in the left pane to manage entity types and their attributes.

An Entity Type is a class of entity, whereas an entity is a specific instance of an entity type. For example, Individual is a Reltio Data Cloud entity type, whereas Jim is an entity (or instance) of type Individual. To learn more about entity types, see What is an Entity Type?.

Attributes are defined as a collection in the entityTypes section of the configuration file.

To learn about an alternate way of configuring attributes, see Configuring Attributes.

Relationships are links between entities, such as HCOs affiliated with an HCP. To learn more about Relationships, see the What is a relationship? topic.
