Workflow EngineWorkflow Engine

• Is embedded in the Oracle8i server

• Uses the process definition created with Oracle Workflow Builder to coordinate the routing of activities for the process

• Monitors the state of each activity in a workflow process

• Signals any changes in the workflow state to the engine using calls to PL/SQL or Java API’s

• Guarantees consistency between the application and the workflow state because of Oracle8i transactional integrity
