The Artemis iOS application aims to replace the current Artemis web platform for iPhone users, providing a more user-friendly interface. The application includes features such as course details, the respective lecture and exercise overview, exercise participation, and instant messaging.
This section examines the subsystem decomposition of the App, as depicted in the referenced figure (app-subsystem).
The primary focus is identifying all App subsystems and their usage of the Core Module.
Subsystems part of the Core Module are highlighted in green, and arrows illustrate relationships between subsystems.
For the sake of simplicity, we do not show all Core Module subsystems.
Therefore the User Session Store, Common Utility, Artemis Profile Info, API Client, Shared Models, Design Library, Shared Services, and Artemis Markdown subsystems are not shown in the figure.
More information on the iOS core module (ios-core-module) can be found here.
The Course Overview subsystem serves as the app's home screen and thus encompasses all other subsystems. Consequently, it has a dependency on the Account, Course Registration, Notifications, and Course View subsystems.
The Course View includes all details about a specific course and therefore uses the Exercises, Lectures, and Messages subsystems. The Exercises subsystem is responsible for displaying all exercises as well as showing detailed information for a specific exercise. It should also make exercise participation possible. The Lectures subsystem lists all available lectures of the course, as well as all the respective lecture units and their attachments. The Messages subsystem handles the interaction with the conversations and their messages.
The Notification subsystem displays the in-app notification center where the user can see past and current notifications with detailed information.
All subsystems where network communication is necessary use the API Client, although we do not depict this relationship in the diagram.
The Login, and Account subsystems manage the user authentication handling. The Push Notification subsystem handles the registration, notification settings handling, decryption, and displaying of push notifications.
