Custom Entities

Custom entities are entities you define from scratch within Negroni. They allow you to model business concepts that are not covered by the standard CDM library.

Overview

Custom entities are defined within a manifest and can have any combination of attributes and relationships that fit your requirements. You can create a custom entity when starting a new manifest or add one to an existing manifest at any time.

Creating a Custom Entity

In a New Manifest

  1. Open the New Manifest wizard flow.
  2. Go to the Create Custom Entity tab.
  3. Enter the entity name.
  4. Click to add the entity.
  5. Click Finish when done.

In an Existing Manifest

  1. Right-click on the target manifest in the Navigator.
  2. Select Add Entity.
  3. Choose the Create Custom Entity tab and enter the entity name.
  4. Click Finish.

Customizing Core Entities

In addition to creating new entities from scratch, you can customize existing core entities by adding or removing attributes and relationship references. This lets you adapt standard business models to your specific use case without losing the standardized foundation.

To customize a core entity:

  1. Navigate to the core entity you want to modify.
  2. Add or remove attributes and relationships as needed.

For inheriting core entity attributes without modifying the original, use Extend Entity instead.
