Question

Draw *Activity* diagram that includes 3 devices.

Please draw it on a paper for it to be clearer
User system:
1- user can choose items with the quantity.
2- then swipe his ID card
3- the request will be send to the admin system.
Admin system:
1-register the request with the user ID& items& quantity.
The Admin System receives the request from the User System and registers it in the Request Management Interface, keeping a record of all requests made by users. This system ensures that only authorized users can make purchases, and that the admin system has a record of all the requests made by the users

Answer 1

To draw the activity diagram, identify the initial node with user actions, draw subsequent action nodes for each user-system interaction, and include the admin system's response, ending with a final node to signify process completion.

Step-by-step explanation:

To draw an activity diagram for this scenario, you must first identify the system of interest, which is a user interface for selecting items, an ID verification system, and an admin system for registering requests. This system allows users to select items and quantities, swipe their ID card for identification, and send requests to the admin system for processing. The admin system receives these requests, verifies user ID, and logs the items and quantities requested. A sketch of the activity diagram would show the flow from item selection, through user verification, to request logging.

Here is how we can approach the drawing part of the activity diagram:

• Initialize with an initial node that represents the start of the process (User chooses items with the desired quantity).
• Draw an arrow leading to an action node representing the 'Choose Items' activity.
• Next, create a path to the 'Swipe ID Card' activity, verifying user input.
• An arrow should then lead to the 'Send Request to Admin' activity, indicating a data flow to the admin system.
• In the admin system, another action node titled 'Register Request' should be drawn to depict the admin's activity.
• Finally, draw an end node to indicate the completion of the process.

Remember to include decision points if there are conditions to be met at any point in the activity flow.
