B.1 Interaction model control styles

Before commencing to create the sequence diagrams for your project one should note that there are typically 3 control style patterns that can be applied to the interactions. These are i) centralized, ii) delegated, and iii) dispersed.

In centralized control there is one component that is the main controller and typically most messages will come from this component. Note, that this violates one of the interaction heuristics.

In delegated control, responsibility is delegated to other components but still coordinated by a central controller.

In the dispersed control components have very few operations that results in many interactions with the other components in the system.

B.2 Lab Deliverables

To do:

1-Design a high-level sequence diagram for TA matching system.

General System Operation

- The TA Matching System is a standalone software package that takes into account TA course and professor preferences and assigns courses to the TAs based on these preferences and constraints on the course and TA.

-The algorithm, should offer some prioritization of the selection criteria to the user based on the following:

TA course choice priority

Professor TA priority

A combination of TA and Professor priority

TA experience priority

For the user option 3 (a combination of TA and Professor priority) the output views should adopt a cell colouring scheme that reflects the selection priority on whether they are:

First TA and 1^st Professor choices

First Ta and 2^nd professor choices

Second TA and 1^st professor choices.

.

2-Modify the high-level sequence diagram to include those Classes that you have defined in your architecture. Choose one interaction model control style and comment on why you made this choice.
