Process Driven Messaging Service

A process driven messaging service (PDMS) is a service that is process oriented and exchanges messages/data calls. A PDMS is a service where jobs and triggers can be put together to create a workflow for a message.

Messaging platforms are considered key Internet infrastructure elements. A concept that once mainly encompassed email and IM has evolved to embrace complex multi-media email, instant messaging, and related fixed and mobile messaging infrastructure. Arguably, everything transmitted on the Internet and wireless telecommunication links are messages.

PDMS exchanges messages for the purpose of all kind of messages/data calls between systems, applications and or human beings that is based upon event-driven process chains.

A process driven messaging service is a service where jobs and triggers can be put together to create a workflow for a message and the workflow can be seen as a process.

A workflow is executed when a trigger is prompted. The trigger causes the activation of one or more jobs which can, in turn, execute more jobs. The workflow will still be active even when all jobs have been executed, but nothing occurs until it is re-triggered.

A workflow in PDMS is used to wrap triggers and/or jobs together to accomplish a flow of actions and events that can be invoked over and over again without repeating the configuration. What also should be noted is that a workflow is a container. A workflow process is a container for a group of workflow statuses and actions, such as moving a record from one status to another. Other than triggers and jobs, it can contain groups or artifacts. The items that can be contained in the workflow are then available to all triggers and jobs within the workflow.

The concept of a workflow can be seen as a template for either part of, or a whole, business process. Workflows can be triggered for a number of different reasons, an example of which could be if something were to happen in the domain or there were to be an explicit call to invoke.

The workflow will be in a state awaiting execution when the workflow, its triggers, and its jobs are active.

When created, workflows require the last job to be added first, meaning jobs are to be listed in reverse order of execution. Jobs and triggers also require the reverse sequential listing of orders when created.

A job creates something such as a task (e. g., sending a message) or affects Standard Objects (e.g. way metadata in a unit). It is a task describing what the system should do and can be several things. A job, when activated, can lead to the execution of another job (for instance: message delivery). It represents what a system does with the data, an activity within the system domain.
