Project: HealthCare Xpress

HealthCare Xpress is a desktop application that is to be used by medical administrator for managing patients that require home-visits and nurses. It helps medical administrators manage nurses, patients, their next of kin and attending physicians.The user interacts with it using a CLI, and it has a GUI created with JavaFX. It is written in Java, and has 10042 lines of code.

Given below are my contributions to the project.

  • New Features:

    1. Uid
    • What it does:
      • Unique Id and the manager to manage operations associated with the uid.
    • Justification:
      • Uid solves the issue whereby the medical administrator may enter very similar persons into Healthcare Xpress.
      • Uid helps to differentiate between these individuals.
    • Highlights:
      • Implementing a unique set of uid was challenging.
    1. Delete Command
    • What it does:
      • Deletes the person based on their uid.
    • Justification:
      • The delete command is an essential command so that the medical administrator can remove persons who are no longer relevant.
    1. Check Similar Command
    • What it does:
      • Deletes the person based on their uid.
    • Justification:
      • The delete command is an essential command so that the medical administrator can remove persons who are no longer relevant.

    • Developer Guide:
      • Target user profile
      • Value proposition
      • User stories
      • Delete command implementation
      • Unique ID implementation

      • Deassign Command
      • Other miscellaneous parts and proofreading

  • Contributions to the Developer Guide ### Assign Feature

    #### Motivation:

    • The assign feature is necessary so that the medical administrator can visually see which nurse is attending which patient’s home visit.

    #### Implementation:

    AssignSequenceDiagram

    Step 1. The user executes assign id/3 id/2

    Step 2. HealthcareXpressParser creates an AssignCommandParser to parse the arguments.

    Step 3. AssignCommandParser checks validity of the given arguments and creates an AssignCommand.

    Step 4. The AssignCommand is executed, and a new InternalEditor is created.

    Step 5. AssignCommand calls the InternalEditor’s methods of editPatient and editNurse.

    Step 6. Model updates the database, and displays all the persons.

    The activity diagram below summarises exception handling of AssignCommand:

    #### Design considerations:

    • Aspect: How the parse interprets the order of uids
    • Alternative 1: Fix the order of the uid, so patient then nurse
      • Pros: There will be less checking needed to deduce the class of the persons involved.
      • Cons: The user experience will suffer as the medical administrator might not be able to accurately remember which uid corresponding to which person, the nurse or the patient.
    • Alternative 2: Have no fix order, as long as one nurse uid and one patient uid is inputted
      • Pros: The user experience will be better as there will be more leeway.
      • Cons: Harder to implement and more testing is required.
