I want to write an application for android, I don’t know what to use, which Oracle or Firebase server?

Question

Android

I will store clients and their tasks, I don’t know what to use so that the application does not freeze, and plus tell me which database to use. PS it is not necessary that it be Firebase or Oracle, you can offer your own version

Answer 1

According to the wording of the question - any base can be used.

Answer 2

Oracle or Firebase?

Isn't it too oily? The muscle is enough for the eyes

Answer 3

The choice of database depends on your task and experience with them.
If you need to save data locally, you can use Room .
If you receive data over the network, then you can use the same Firebase, but you should not forget about quotas / restrictions.
If you use MySQL or PostgreSQL, then you will need to raise the VPS server and it is desirable to transfer data through the API so as not to connect to the database on the client.
For a more detailed and accurate answer, there is too little input from you.
