Figure 1: (simple) Jetfire Data Model


It is important to understand the relationship of Jetfire objects to:
  • Design Workflows
  • Design Web Pages with Jetfire Workflows

Jetfire provides a flexible way of connecting data. The typical way of connecting data is explained on this page.

Figure 1 is a simple diagram that shows the relationship between Subscription, Workspace and Workflow.

The Subscription

The Subscription maps to the data storage of a set of workflows that a user can access.
  • We also refer to the subscription as the Server Nexus.
  • Jetfire provides the ability to create multiple subscriptions.
  • Each subscription is contained in its own dedicated data storage.

The Workspace

The Workspace can be viewed as a folder where workflows are stored. It is used to organize Workflows in the subscription.
  • Workspaces belong to a Subscription.

The Workflow

The Workflow is the basis of Jetfire. Our basic view is that "Everything is a workflow". Hence, all Jetfire objects inherit from Workflow.

Figure 2: Roles and Access Control Lists

Roles

Figure 2 shows a set of Users (who are logged in) and a set of Workflows. Roles provide logged-in users with permissions for accessing workflows.

All workflows have a Roles property that contains a list of Roles. Roles map to permissions for workflows.

Access Control Lists

All workflows have an ACL property. The Access Control List 'controls who has access to the workflow'.

Roles and Access Control Lists

Figure 3 shows how roles map to access control lists to provide access to workflows. e.g. a logged-in user with Role A can access Workflows with Role A in its Access Control List.
