Implementation Overview

Factory Command

Creates an instance of a root entity and persists it in the datastore.

Inside Factory Command, solution engineers can call Events

Inside a factory command implementations there is a function called available(). This is used to check the necessary pre-conditions of the command. If the function returns true then the command will be executed, otherwise, the command will not be executed at all.

Instance Command

Manipulates the values of one or more properties of an already existent instance of an entity.

Inside Instance Command, solution engineers trigger Events

Inside an instance command implementations there is a function called available(). This is used to check the necessary pre-conditions of the command. If the function returns true then the command will be executed, otherwise, the command will not be executed at all.

Domain Service

Can perform operations throughout different domain namespaces.

Inside Domain Service, solution engineers can call Factory Command, Instance Command, Domain Service, and Events

Events

They are published to indicate that some action

An event that is successfully published will automatically execute the script of the Agent that is related to this event.

Agents

When an event is triggered, then agents are automatically executed as consequence of the action that triggered the event.

Inside Agents, solution engineers can call Factory Command, Instance Command, Domain Service, and trigger Events

Operation

Can perform operations throughout different domain namespaces.

Inside Operation, solution engineers can call Factory Command, Instance Command, Domain Service
