Dear all fellow NestJS developer,

I am writing to seek for your advice regards experience in developing Micro Service for Notification, since I kinda want to know your idea base on your experience what functionality should be having, and how the DB schema in postgres should be structure, here is summary of business flow. Since we are start up business : we are having front end system which sale department will be submit the application, then the application will be sent to review department, when they accept the application they will push to operation team to issue documents, and in this process, all the related field should be notified in regards of status of that application, if you are building the Microservice for that what functionality should be developed, and how will you structure the DB Schema in Postgres, currently we are having application service to handle issuing application, and Review Service to handle submitted document, yet I am stuck at structuring best practice of Notification Service
