1. Introduction

Archangel is a desktop application for managing patient appointments designed for usage by private clinic doctors, optimized for use via a Command Line Interface (CLI) while still having the benefits of a Graphical User Interface (GUI).

Archangel integrates storing of patient data and scheduling patient appointments in a single application. It supports adding, editing, deleting of patients/appointments and facilitates search using filter commands to help improve your experience in handling patient data. For those familiar with command line interfaces, Archangel can get your patient management appointment done faster than traditional GUI apps.

1.1 Archangel User Interface

You will be using the interface displayed below when using Archangel. It consists of a “Main Dashboard” tab and a “Calendar” Tab.

Main dashboard tab:

  • Appointment List: Shows the list of appointments that are scheduled.
  • Patient List: Shows the list of patients that are stored within Archangel.
  • Status Box: Displays the response of Archangel for commands that are entered by the user.
  • Command Box: Input box for the user to enter their commands.

Calendar tab:

  • Calendar: Shows the list of appointments that are scheduled within the current week in an in-built Calendar.
  • Patient List: Shows the list of patients that are stored within Archangel.

(All-Patient list is the list under view!)
Figure 2.2.2.2: After `p-find alex`.

    as its implementation purpose is to assist the user in undo-ing his changes, filter commands do not make changes to the data.
    It also does not work with p-edit as the design requires patient details to be accurate as of time schedule, such that the records can accurately reflect the patient’s conditions at the time of the appointment.
  • A list of commands that can be undone can be found in the table under Command Summary.
  • This command can be succeeded by a redo command.
