Project: Source Control

Source Control is a desktop application for CS1101S professors to manage the performance of their students. Users interact with it using a CLI, and it has a GUI created with JavaFX. It is written in Java, and has about 10 kLoC.

Given below are my contributions to the project.

  • New Feature: Added the ability to add groups.
    • What it does: allows the user to add groups within the module. Students can also be added to the new group within the same command.
    • Justification: This feature is necessary for the target user to know which groups a student belongs to. It also allows for detailed analysis of the performance of a particular group, relative to the cohort.
    • Highlights: This enhancement is the sole entrypoint for the creation of groups. The implementation was challenging as there were many edge cases to consider, such as if a student to be added was specified more than once.
  • New Feature: Added the ability to render charts for better visualisation of assessment performance.
    • What it does: allows the user to visualise how the cohort performed in an assessment using a histogram.
    • Justification: This feature is necessary for the target user to analyse assessment results easily, such as whether the score distribution follows a desired bell-curve shape.
    • Highlights: This enhancement is the first feature in Source Control that dealt with JavaFX Charts. The implementation was not trivial as JavaFX Charts were not easy to work with, and many style customisations had to be made for the chart to fit well with the application’s theme.
