On line Image Management Design Evaluation

By Aces Group

Following is the specification of various diagrams that were developed by the team for the application. All diagrams were assessed by Dr. Hankley

Use Case Diagram

The System has the following Actors and each Actor has the following Use Cases

Customer

            Use Cases:

                        Register

                        Place Order

                        Check Order Status

                        Browse Image

                        Download Ordered Image

Photographer

            Use Cases:

                        Upload Image

                        Edit Image Information

                        Give Permission to View Image

Manager:

            Use Cases:

                        Approve Order

                        Reject Order

                        Prepare Invoice

                        Add Photographer

Class Diagram

User:

            This Class represents a User Object.

            Specialization of User Class are the Customer, Photographer & Manager Classes

UserFacade

            This Class represents a session bean that performs user related functions like:

            authenticateUser(user name, password) etc

Order Header

            This Class represents an Order object that is created by Customer so as to get images

Order Detail

Each Order Header as Multiple Order Details. Thus if an Order has ten images there will be one order header and ten order details

Order Façade

            This Class represents a session bean that performs order related functions like:

            createOrderHeader(customer id)

            createOrderDetail(order no, image name)

Sequence Diagram

Theoretically, there should be a sequence diagram per Use Case. However, sequence diagrams were developed for the following use cases:

-          Authenticate User (User)

-          Place Order (Customer)

-          Upload Image (Photographer)

-          Approve Order (Manager)

Thus, at least one sequence diagram was developed per Actor.

Activity Diagram

An Activity Diagram was developed for Order Processing Function starting from Customer placing order, Manager approving/rejecting the order, Photographer fulfilling the order and lastly Manager invoicing the order.
