Systems Design

Our team of systems analysts has delivered to you the analysis model of the SGAI system. See the sample solution of Assignment 1. You are requested to work on the design phase as follows:

Part I. Original Design

S1.  For the use case “Register”, transform the analysis use case documentation into design use case documentation.

S2.  For the design use case “Register”, model object interactions and behaviour using the standard steps:

(a)  Identify and categorize design classes.

(b) Identify (additional) attributes.

(c)  Create a communication diagram to model high-level interactions of the design objects.

S3.  Identify the behaviour and responsibilities.

S4.  Update the class diagram from the sample solution of Assignment 1 to reflect any necessary changes due to Steps S1 to S3 above.

Part II. Systems Redesign due to Requirements Change

The users are making a request for a change of requirements. In the original requirements on 3 October 2023, they wrote that

“(3) Once confirmed, an hange the requirements as follows:

“(3) Once confirmed, account will be setup.”

However, they would like to can activation link will be sent to the student’s email address. The student clicks the link, then an account will be setup.”

You are requested to redesign the system according to the new requirement.

Tasks and Deliverables

For PartI.  Submit all the design deliverables, including the design use case description for “Register”, the new use case diagram (if different), the list of categorized design classes,   the list of attributes, the list of behaviour and responsibilities, the communication diagram for “Register”, and the updated class diagram.
