Which solution to choose for data storage?

Question

Java

In the process of working in the application, text is written to an ArrayList (5-6 sheets, each with several hundred lines. Each line is a separate word), there will be no work with these words separately, but when you open the list, you need to get the entire contents of each sheet.
Now I save each sheet to my .txt. Is it possible to leave it like this or is it better to write it to the database? If so, how can such a record be implemented?

Answer 1

I prefer to write large amounts of data to the database.
Connect room, ormlite or any other ORM and use SQlite.

Answer 2

The ideal solution is a remote server with a deployed database and Rest API to it.
You can use Firebase for free.
