B4J Question Appointment Reminder System

[walterf25]

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

[server] Background Workers

jServer v2.70 adds support for background workers (https://www.b4x.com/android/forum/threads/updates-to-internal-libaries.48274/#post-465493). A background worker is a class instance that is initialized by a background thread. You can keep the class instance running for as long as the server is...

Thanks Erel, that's what I was looking for, I should be able to query the database and compare the saved date and times against the current date and time and send notifications for upcoming appointments.

Awesome.
