Ohh, SQLite isn't "one" db. SQLite is file-based. I.e. a database in e.g. PostgreSQL (containing several tables, views, indexes, etc.) would translate to one SQLite file (e.g. mydatabase.db3 or myappdata.sqlite). And each app has its own file/database. If the file corrupts, then it's only affecting that specific app. (However, SQLite is pretty robust.) And since these are just files, you can backup them together with the application. No need to export data or shutdown the database first.
