Workflow Definition
- WorkflowID (Primary Key): Unique identifier for each workflow.
- Name, Description: Description of the workflow and its purpose.
- Start Node, End Node: Start and end nodes of the workflow.
Task
- TaskID (Primary Key): Unique identifier for each task.
- Name, Description: Description of the task and its requirements.
- WorkflowID (Foreign Key): Reference to the workflow associated with the task.
Transition
- TransitionID (Primary Key): Unique identifier for each transition.
- Name, Description: Description of the transition and its conditions.
- Source Node, Target Node: Source and target nodes of the transition.
User
- UserID (Primary Key): Unique identifier for each user.
- Name, Email: Contact information of the user.
- Role: Role or position of the user within the organization.
Workflow Instance
- InstanceID (Primary Key): Unique identifier for each workflow instance.
- WorkflowID (Foreign Key): Reference to the workflow associated with the instance.
