Project: HealthVault

HealthVault is a hospital management system designed to help nurses manage their workflow. It is a desktop app capable of managing doctor, nurse, patient and inventory information, optimised for use through the command line interface. A user with fast typing skills will be able to navigate through the application with ease and greater efficiency as compared to a normal Graphical User Interface application. This program is written entirely in Java and has about 6 kLoC.

Given below are my contributions to the project.

• New Feature: Created the Schedules for Nurses menu and functionalities.
  • What it does: Provides the ability to add/delete/list schedules for different nurses. Schedules are sorted by date.
  • Justification: Being able to efficiently add/delete/list schedules allows nurses to quickly get into their workflow with minimal disruption, reducing downtime and wait-time of patients.
  • Highlights: The NurseSchedule Class implements the Comparable Interface allows the ordering of the Schedules to be sorted based on the compareTo() function. The sorting is so that the nurses will be able to view their next closest schedule on the application.
• New Feature: Added the ability to store and load data
  • What it does: Provides the ability for continuous usage, even after the program is terminated.
  • Justification: Nurses need to quickly get to work and it would not make sense for them to re-enter all their relevant schedules after terminating the program
  • Highlights: Due to the vulnerabilities of corrupted data files in this enhancement, extra data validation components had to be added to the reading of files. This ensures that the program does not deviate to far from normal operation should somebody tamper with the file.
• New Feature: Added Cross-Validation
  • What it does: Ensures that all schedules added are with valid Nurse ID’s and Patient ID’s (i.e present within the database)
  • Justification: If no checking is done across the different data files, schedules with non-existent Nurse ID’s or Patient ID’s will be added in to the system. This results in wasted resources and poor scheduling for nurses, something that this program aims to minimize.
  • Highlights: Due to the modular nature of our application, the loading of data files of other types was easy to implement. However, extra care had to be taken to ensure that these files were not corrupted as well.

• Code contributed: RepoSense Link.
