ALM Octane is an entity-relationship application. Using the ALM Octane REST API, developers can retrieve and perform CRUD (create, read, update, delete) operations on the entities that are available in the ALM Octane graphical user interface. For details, see REST API.

ALM Octane provides a built-in client that lets you make API calls from within the ALM Octane UI. For details about how to use the interactive API client, see Interactive API client.

In the ALM Octane Help menu , click Entity Relations Explorer. This provides you with a graphical interface which shows you the relations between entities, helping you create API calls and OData reports.

For example, if you want to create an OData report on feature quality you can use this to see which entities are relevant, and what are the relations between them.

Note that you can use presets which provide preconfigured sets of related entities, or enter your own entities in the From and To fields. You can drag nodes to change the layout, and hover over an entity to see only that entity's relations.
