Presenting Existing System Architecture
Existing application architecture can be represented by a diagram grouping the main applications and flows exchanged in the system under study.
An application architecture diagram is created from an application via command New > Diagram.
The following example presents the internal architecture application diagram l"ADD Purchasing (Flows)" of the "Purchasing Management System" application.
Equipment purchases for boat maintenance are made directly by the Representation Office, using the "Equipment Purchasing" application. This application calls a "Purchasing Management" application located centrally at Headquarters.
If the purchase involves a new type of equipment or a new supplier, a contract request is sent to the supplier using the application at Headquarters. The supplier returns a contract proposal.
In the other cases, a representative from the Representation Office sends a purchase order to the supplier using the "Equipment Purchasing" application.
Reception of purchases delivered from the supplier is handled by the "Boat Inventory Management" application at the Representation Office.
The invoice sent by the supplier is managed in the "Billing" application at Headquarters.
