This image displays the workflow process.The Start task begins the process when triggered by an event within an application. Based on that change, the system invokes a message task, which sends a message to a designated user (an approver) to review the change and either approve or reject it. The lines in the graphic are labeled Approved and Rejected. If the approver approves the change, a business function updates the database with new information. The system then sends a message back to the originator, acknowledging that the changes were made. If the approver rejects the change, the system sends a message to the originator informing him or her that the request was rejected. The database remains unchanged if the request is rejected. The operations are described in detail in the text preceding the image.
