The business rule engine

Nuclos has a business rule engine to implement any company-specific behaviour – wherever the other low-code mechanisms are not enough. Typical cases: complex validations, generating data for downstream systems, calling web services or changing data automatically depending on events.

Menu: Configuration → Rule sets

Three kinds of rules

Server-side rules – event-driven business logic on the server (insert, update, status change, job, object generation …).
Client-side rules – immediate calculations/reactions in the form.
Generic implementation – reusable logic for generic business objects.

API & assignment

The available method calls are documented in the Nuclos API. Rules are assigned in the server rule manager or directly on a status transition.

Events

Server rules react to events such as create, update, delete, status change, print, job, object generation and more – each also in the final variant. All events (with examples) are documented in the German space for now.
