Hi all, i'm just trying to figure out where to begin to create an Appointment Reminder System, off the top of my head i know I can use FireBase Push notifications, i can probably use B4J to create a web server that can take care of subscribing customers to certain topics etc.
I'm just looking for ideas on how to implement an appointment Reminder system, i really have never done anything like that and would like to start playing around with it, let's say i have an mobile app and I can book a client at a certain date at a certain time, if i'm able to send that information to a web server and store that data on a database, how can I set some sort of background service to continuously check the information in the database and send a push notification to all and any of the clients that have appointments coming up.
I'm not asking for code, i only need some sort of explanation on what direction to start and how to begin.
Thanks all,
Walter
