I'm in the process of developing an app for the first time and I'm unsure of how to move data to a secure location, update it periodically and import it while the app is live so that the clients can receive it in real time. I'm thinking I would need to incorporate SQL, but I don't know how to create objects dynamically as the app is running for each respective row in a table. The app will involve posting, so naturally some might be removed by the admin or the user, so the post ID's will shift over time. Also, since the post count is constantly changing, I would need the amount of objects generated to be fluid. So I need to find a way to store the post data, and keep the data the same for both the database and whatever variables/objects are running in java. However, if I have to constantly query the database I feel like that would be very sloppy and slow. If anyone could link me to an article or a simple answer on how to accomplish this I would be very grateful. Thanks for your time.
