How do I notify a process of an SQLite database change done in a different process?

Question

Let\'s say I have two or more processes dealing with an SQLite database - a \"player\" process and many \"editor\" processes.

The \"player\" process reads the database

Answer 1

I think in that case, I would make a process to manage the database read/writes.

Each editor that want to make some modifications to the database makes a call to this proccess, be it through IPC or network, or whatever method.

This process can then notify the player of a change in the database. The player, when he wants to retrieve some data should make a request of the data it wants to the process managing the database. (Or the db process tells it what it needs, when it notifies of a change, so no request from the player needed)

Doing this will have the advantage of having only one process accessing the SQLite DB, so no locking or concurrency issues on the database.
