This project is a concept project designed and developed to be submitted as the CA of the module Distributed Systems of a Higher Diploma Level 8 in Computer Science in Software Development.

The purpose of this project is to design and build a smart health application using gRPC and jmDNS to develop a client-server application in a local environment.

The Auth Service is responsible for registering and logging in users. Uses a CSV file to persist data as a DataBase. It has a proto file and its corresponding Server and Client files / classes.

The methods implemented in this service are:

  • RESPONSE (Newly created Appointment)
• get() => Simple RPC
  • REQUEST (ID)
  • RESPONSE (Appointment matching ID)
• update() => Simple RPC
  • REQUEST (Patient ID, Doctor ID, Dat-Time)
  • RESPONSE (Updated Appointment)
• cancel() => Simple RPC
  • REQUEST (ID)
  • RESPONSE (Deleted Appointment)
• shiftList() => Bidirectional streaming RPC
  • REQUEST (Stream of Doctor IDs)
  • RESPONSE (Stream of Appointments for each Doctor)

The Prescriptions Service is responsible for managing prescriptions. It performs actions for create and view all prescriptions. USes a CSV file as a DataBase in order to persist and store data. And it has a proto file and its corresponding Server files / classes.

  • RESPONSE (Newly created Prescription)
• addDrug() => Simple RPC
  • REQUEST (Drug Name, Doses, Comments)
  • RESPONSE (Newly created Drug)
• viewAll() => Server-side streaming RPC
  • REQUEST (Empty)
